With the help of this tissue you see. It decides how far or close you can see. Surgery of eye takes very less time. Laser rays burn the tissue around your eye’s cornea .When this tissue is removed, the laser then reshapes the cornea. Excimer is high quality and high precision laser used in laser eye surgery. When the burned tissues is removed, then the light rays will be refracted properly and fall on the retina of the eyes. Then your vision will increase. Vision correction problem can be solved up to more extent.For every other person it is reshaped in different way. You couldn’t find any simpler way to correct eye vision than this eye surgery. It is available for every body of all age’s .But for children doctors will suggest as per eye vision of your child. This treatment is done everywhere in the world.

There may be experience of slight eye irritation in few cases. If you find more problems then consult your doctor Cataract is also a vision problem. You will have problem in seeing. In cataract, the light will not reach the convex lenses of eye or it will be partially blocked out. It’s a normal case of aging person. In most cases, both eyes are affected by cataract but one eye is more affected than other one. In starting time it is minimal; people don’t feel it or know they are sufferer of cataract. Those who have more cataract problem they have vision problem in daily lives. They may have problem of color vision and also double vision. Cataract people have also problem in driving at night. In most cases doctors gives glasses and lenses to their patients. If this is not enough then surgery is suggested. Laser surgery is one way to remove cataract. This surgery is carried out by the uses of laser light instead of ultrasound. Cataract surgery is not carried in normal doctor’s clinic. It needs more care with all instruments in opening eyes. It takes weeks to be in normal position of eye or in healing. It is suggested to patients first get the treatment of one eye then the other one.

Accuvision provides laser eye surgery, laser vision correction and laser … This includes eye mapping, vision testing and medications related to the laser surgery. LASIK laser eye surgery patients often have good vision by the day after surgery. LASIK, or laser in-situ keratomileusis, is the most widely performed laser eye surgery for treating a wide range of common vision errors. Most reputable centers for eye laser surgery note that 20/20 vision from laser-corrected surgery may not be like 20/20 vision with corrective lenses.

Great Information On Laser Eye Surgery
Laser eye surgery is a medical procedure consisting of the use of laser for reshaping the surface of the cornea. It is used to improve myopia (shortsightedness), hypermetropia (long sightedness) or astigmatism. The first information on laser eye surgery dates back from over twenty years ago.
During laser eye surgery, an excimer controlled by a computer is used to remove tiny amounts of corneal tissue. The aim of the procedure is to restore normal vision, relieving the patient from wearing glasses or contacts.
In one type of laser eye surgery, the outer layer of the cornea, also called epithelium, is removed and an excimer laser is used to reshape underneath tissue. This procedure is called photorefractive keratectomy (PRK).
In a newer procedure, a microkeratome is used to cut a flap in the corneal tissue, which is then lifted and an excimer laser is used to reshape underlying tissue. In the end, the flap is put back to its place. This type of laser eye surgery is called laser-assisted in situ keratomileusis (LASIK). Nowadays, it is more commonly used than PRK.
Information on Laser Eye Surgery Procedure
The excimer laser is a special type of laser that does not burn the corneal tissue, but vaporizes a small quantity of the cornea each time a beam is pulsed onto the eye surface. The number of pulses and diameter of the beam are carefully controlled by a computer to enhance accuracy.
Local anesthetic eye drops are used before the surgery. The procedure takes a few minutes per eye. The actual time when the laser is used for reshaping the corneal tissue is generally less than a minute.
Various eye conditions require different types of treatment:
l Myopia – the central peak of the cornea has to be flattened in order to reduce short-sightedness and improve vision.
l Hypermetropia – the central peak of the cornea has to be made steeper in order to improve vision. The laser is applied to the edges of the cornea.
l Astigmatism – this is a condition where the cornea is not evenly curved. The laser is applied more linear to improve vision.
Information on Laser Eye Surgery – Post Surgery
After laser eye surgery, you should expect some minor discomfort. However, you should be able to see, although not very clearly. You won’t be able to drive on your own, so you need to have someone drive you home or take a cab.
Information on Laser Eye Surgery Possible Side Effects
Just like any operation, laser eye surgery involves a few risks as well. You should have some information on laser eye surgery and its possible complications and side effects before deciding you want to have this type of surgery.
l Treatment not successful – this may be the result of either under treatment and over treatment. You may need another surgery to enhance vision.
l Dry eyes – you might have to use eye drops.
l Delayed healing – the flap or the outer layer of the cornea might not heal properly and require follow-up treatment.
l Infection – in case of an infection, you may need to follow an antibiotic treatment.
l Superficial scarring – a second procedure might be needed to repair scarred tissue.
l Excessive thinning of the cornea – vision problems may return and you might need to use contacts or have another surgery.
l Sensitive eyes – some patients experience excessive sensitivity to glare, which makes driving more difficult.
l Blurred vision – ‘halos’ might result from the surgical procedure, but usually they fade out over time.
Before deciding on a certain type of laser eye surgery, you should consult a doctor to examine your eye condition thoroughly, provide you with information on laser eye surgery risks and benefits and give you some advice on which procedure is best for your specific problems.
Laser Eye Surgery Provides Freedom from Glasses and Contacts
There are many renowned as well as diverse laser eye surgery clinics that offer the best available treatments at the most affordable prices and also achieve high quality clinical excellence. Laser eye surgery could cost approximately $1000 and the quick and simple procedure offers freedom from blurred and incorrect vision and provides an alternative to wearing glasses as well as contact lenses.
Laser eye surgery is not like other operations in that it is only performed on people with healthy eyes in order to cure eye diseases. There are different laser eye surgeries such as lasik, epi-lasik, wavefront lasik/epi-lasik, and femtosecond lasik or the new state of the art all laser lasik.
Lasik, Epi-lasik, and Wavefront Surgeries
Lasik is used in correcting a broad spectrum of prescriptions and is most suited for the correction of mild to severe short sight, mild and long sight as well as astigmatism where the patient would generally recover in a day’s time. Epi-lasik is not as invasive as lasik and can be used to correct mild to moderate short sight as well as astigmatism.
Wavefront lasik/epi-lasik is a treatment that can be customized and is designed to correct unusually shaped eyes as well as cases of unsatisfactory results from using lasik or epi-lasik treatments and is greatly instrumental in improving night vision. When the patient is undergoing laser eye surgery the surgeon most often uses a device known as the Excimer Laser which helps to shape the patient’s cornea forever.
In PRK, the surgeon utilizes a laser beam that is guided with the help of a computer to vaporize small amounts of tissue that is present on the surface of the cornea. Using PRK helps in removing the right amount of tissue and reforms the cornea to enable corrected vision and the healing process may last a week or so.
Laser eye surgery is usually performed by very experienced as well as highly trained specialists and the results vary from satisfactory to excellent. In many cases the patient finds his or her life vastly improved as a result of such treatment since they may not have to use prescription glasses or contact lenses after the surgery. However, the patient should have realistic expectations before the eye surgery is performed and for those who are above 40, they should know that it may still be necessary for them to use reading glasses, even after the surgery.
Things You Must Know About Laser Eye Surgery
Nowadays, it is just not practicable to wear glasses every day. Many people do so, but many more decide to wear contact lenses every day, or part of every day. However, even contact lenses have their problems. One of the main problems is that you simply have to put them in every single day. Everyday, you have to wake up with your blurry eye and brush your teeth and put pieces of plastics in your eyes. If you are tired of doing this everyday, you are definitely not the only one.
Just imagine being able to wake up in the morning and not have to put on your glasses or your contacts in order to see well. This is something that many people have to cope with on a daily basis, particularly as we get older. Not only do you have to worry about using contacts or glasses each day, but you also have to worry about the recurring costs and about the risk of losing them. How about the trouble of having to get special equipment for things like underwater recreation? The good news is, laser eye surgery has changed all of this for you. It will actually let you to see the world without the use of glasses or contacts.
What Is Laser Eye Surgery?
Laser eye surgery is a procedure where lasers are used to fix the parts of your eyes that create bad eyesight. It is truly a way for you to realize how much you want to change about yourself. For a long time, the only types of surgeries that you could do were cosmetic surgery. Well, laser eye surgery lets you change not how you look to the rest of the world, but how you look at the rest of the world. This is a type of surgery that helps you actually correct a vision problem.
Keep in mind that this doesn’t work for everyone, but for those for which it works, laser eye surgery have been able to actually repair people’s eyesight.
How Does It Work?
Laser eye surgery employs the laser technology to correct the lenses in your eyes. As you get older, or for whatever reason, the lenses in your eyes have gone out of whack. It’s for this reason that you have to use eyeglasses or contacts to do even the simplest things, such as watching TV or reading. By using lasers to correct the position of these lenses, you’ll no longer need to use vision enhancers to see clearly again. You can just open your eyes and see with your own vision, as nature intended.
Is It For Me?
Check with your doctor or your eye doctor to make certain that your eyes are done changing, and also to make sure that getting this surgery will be useful to you. If it is something that is actually going to assist you in your life and alter your whole outlook as far as seeing goes, then it is something that you should think about. It could be away to help yourself get back on track health wise.
How Do I Find A Good Surgeon?
For your own safety, you will need to go through a checklist thoroughly and only when you are satisfied with the answers you may go ahead with the laser eye surgery.
The first thing you should look at is the experience of the surgeon. You will absolutely not want to have a new doctor performing your eye surgery. Ideally, he should have at least two years of experience. On the other hand, if the doctor has more than 10 years experience, it is not good news too. You should ensure that he is aware of the modern techniques. The laser technology is about a decade or so old, hence, you should make sure that your surgeon is abreast with the latest developments.
The next thing you should consider is the certification of the doctor. This is a very imperative factor about the surgeon you would select to carry out laser eye surgery. Take note that having an ABO or American Board of Ophthalmology certification does not mean that the doctor is also certified with laser eye surgery. This is why you should seek a surgeon who is rather certified by the ABYS or the American Board of Eye Surgeons since this is a certification that is peer-approved and hence, the best one can have for practicing laser eye.
Next, you will need to go through a few pre-surgery procedures and tests to make sure that you know what these are and for what reason they are carried out. Good planning, in terms of finances and mobility, would go a long way to minimize the inconvenience that such tests would be able to create.
Last but not least, you have to make sure that the surgical clinic has the right kind of equipment. You may also check to see the condition of this equipment and make sure that they are well maintained.
Laser Eye Surgery Side Effects
For people with myopic or short-sighted, the prospect of having a perfect vision is certainly a dream come true. People with short sightedness problems would have probably at some time or other wondered about the benefits of having a lasik laser eye surgery to correct their vision.
Since the advent of lasik laser eye surgery, this dream is now a reality for millions of people all over the developed world. This article raises some dangers and side effects of this surgical procedure.
In the original version of the laser eye surgical procedure, the PRK, which is an acronym for photorefractive keratectomy, involves the complete removal of the cornea’s outer layer to operate underneath it and later let it to grow back on its own.
However, with the lasik surgical procedure or laser in situ keratomileusis, eye surgeons can now peel back the cornea surface to operate underneath it and then return the cornea to its original position.
Now, the bad news about the surgery is that there can be some side effects and complications just like in any other surgeries. Some people who have had lasik eye surgery done have found that not only did their vision had not improved, but are seriously damaged by the eye surgery.
The surgery permanently changes the physiology and optics of the eyes. Therefore potential eye surgery patients should always be aware of the risk-benefit ratio and whether is it worth to risk the dangers and side effects to the eyes. The benefits are that you can do away with glasses or contact lenses, probably permanently. However, the risk of permanent damage to your vision can be palpable and alarming.
In a ‘Review of Optometry’ report, up to one in six patients who undergo lasik laser eye surgery end up with complications and side effects. This ratio is indeed alarming.
Complications and side effects arising from the lasik eye surgery include distortion of vision, such as irregular astigmatism, which cannot be corrected by eye glasses. Others experienced deterioration in the quality of their vision or very bad dry-eye side effects. Some very unfortunate patients have reported having double vision or even triple vision arising from a lasik laser eye surgery.
For patients who do not suffer any side effects, it is certainly an undoubted positive life changing experience. For example, Richard Branson of the Virgin fame or notoriety, is a huge fan of lasik laser eye surgery as the surgery has transformed him from being ‘blind as a bat’ to having an almost perfect vision. Till this day, he is still gushing praises on lasik laser eye surgery.
However, on the other hand, Margaret Dolan from Ireland is a victim of the surgical procedure went wrong. After her surgery, her eyes developed a complication known as Post-Lasik Dry Eye.
Margaret Dolan needs to add artificial tears to her eyes many times a day and throughout the night just to keep the eyes moist. Patients who suffer from this dry eye syndrome usually have the symptoms for about two to three months after their surgeries and then the symptoms will disappear.
However, for some very unfortunate people, their conditions do not improve with time and they need to drop artificial tears on their eyes for the rest of their lives. This can be very frustrating and distressing for the unfortunate victims.
So if you are considering a lasik laser eye surgery, do discuss the possible risks and complications that may arise from of the surgical procedure thoroughly with your eye surgeon and get as much information as you can before you reach a decision.

Throw Away Those Glasses: Go For Laser Eye Surgery
For Julie, my best friend, world meant black without her spectacles. The poor myopic girl became the butt of social ridicules because of these thick glasses of hers. At twenty five she used to look like forty years old because of her glasses. Yes, she tried contact lenses once, but she wasn’t comfortable with them and the glasses were the only bridge between her and the world, until the summer of 2000, when she underwent laser eye surgery. Since then everything has changed for her. In her own words surgery brought her freedom; freedom to see the world with her own eyes without any kind of dependence.
Julie is not alone in her experience. There are thousands all across the USA, who are taking to Laser Eye Surgery, the most exciting advancement in ophthalmology. The traditional corrective measures for problematic eye sight involve using spectacles or contact lenses. But in recent years laser surgery seems to replace these traditional devices of correcting eye sight problem.
But what is laser eye surgery?
Laser eye surgery is a surgical procedure intended to correct common vision disorders, referred to as refractive disorders in ophthalmology which include myopia or nearsightedness, hyperopia or farsightedness and also astigmatism or distorted vision.
In this surgery, the laser is aimed at the cornea, which is the outer and clear round structure covering the iris, the colored part of the eye and the pupil. The surgery intends to gently reshape the cornea by changing the thickness of the tissues of cornea. No matter whether you are far sighted or near sighted, the surgery will help your eyes bring the images into proper focus.
Can you opt for different types of laser surgery?
Yes of course you can. Currently there are mainly three types of laser eye surgeries, which you can choose from depending on the type of your eye problem and your budget.
So far LASIK is the most popular type of eye laser surgery that uses the most advanced technological equipment. This is a procedure, which involves carving out of a thin layer of cornea to create a flap. The objective of this procedure is to direct the laser to the tissues lying underneath. The flap which is replaced grows back naturally. And you get an improved vision almost instantly.
The next option is EPIFLAP or LASEK surgery. In this process, the outer layer of cells on the eye is partially removed to expose the cornea. Then laser is applied to flatten or reshape the cornea and the outer cells are pushed back. Just a matter of few days and you get impeccable vision.
The last and oldest option is PRK, which is performed on an outpatient basis with local anaesthesia. In this refractive surgery, laser is applied to remove microscopic amounts of tissue from the outer surface to reshape cornea.
Is it safe?
The laser eye surgery is a surgical procedure, approved by The US Food and Drug Administration. So you can understand there can be no question regarding its safety. But of course there are certain differences of opinion relating to its result, because the procedure is relatively new and long term effects of this surgery are still unknown.
If you are still doubtful, let me share with you a piece of information: according to a certain estimate, more than one million Americans every year undergo laser eye surgery to get rid of their glasses and contact lenses and the number is still increasing. A more valid proof of its growing popularity is the diminishing cost of the procedure.

So if you are considering a lasik laser eye surgery, do discuss the possible risks and complications that may arise from of the surgical procedure thoroughly with your eye surgeon and get as much information as you can before you reach a decision.
Risks and Complications of Laser Eye Surgery
Most patients who undergo refractive surgery are delighted with the results. However, just like any other surgical procedure, there are also some risks that come with it. This is why it is very important to be aware of the possible complications, effects and laser eye surgery risks.
Here is a list of the most common laser eye surgery risks, and complications
In order to understand the complications, there has to be a simple understanding of the procedure of Lasik eye surgery. Lasik eye surgery involves the cutting of a small flap in the front covering of the eye or cornea. The flap is lifted so that the laser may reshape the eye and then the flap is replaced as a type of bandage.
The flap is cut using a type of bladed instrument called a “microkeratome” or else with a laser. The surgeon’s preference determines what technology is used. Using a laser to perform this portion of the procedure allows for more precision and, therefore, fewer complications are likely to arise.
Now, if the flap is not cut correctly it may fail to form properly to the surface of the eye. The flap might also be cut too small or thin, which would cause wrinkling upon the attempt to adhere the flap to the surface of the eye. These complications can lead to an irregularly shaped eye surface and in time may lead to astigmatism or blurry vision.
Vision Loss
After the procedure, a very small percentage of all patients experience a vision loss which cannot be corrected with glasses, contacts or a second surgery. This is a very rare, but very serious laser eye surgery risk.
Debilitating Visual Symptoms
Some patients experience halos, glare or double vision after surgery. This causes serious night vision problems. Even if they have a good vision on the vision chart, they may not see well at night, in fog or in other situations of low contrast. They may even see worse in these situations than they did before treatment.
Under Treatment or Over Treatment
This is a very frequent laser eye surgery risk. Only a small percentage of patients obtain 20/20 vision after surgery without glasses or contacts. You may need additional treatment to enhance vision, but this is not always possible. Even if you used to wear very weak prescription glasses before treatment, you may still need glasses or contact lenses afterwards. If you used to wear reading glasses before, you might still need them after surgery.
Severe Dry Eye Syndrome
Another laser eye surgery risk is to develop serious dry eye syndrome. After surgery, your eyes might not be able to produce enough tears for keeping moist. This not only produces discomfort, by can also reduce quality vision due to permanent blurring and other problems. This eye condition may be permanent. It is usually treated with intensive eye drop therapy, but other procedures can also be used.
Results Diminishing with Age
Another laser eye surgery risk is for results to decrease over time, especially in patients with farsighted vision. If your manifest refraction (an exam with lenses before using dilating drops) differs from your cyclopegic refraction (another exam with lenses after applying dilating drops), the chances of getting this side effect are higher.
For newer technologies, there is not enough research data available. As some of them have been developed only a few years ago, long-term effectiveness and safety cannot be determined yet. Even though they are more advanced, they might have some unknown long-term side effects.
As with any surgical procedure, there are a variety of complications. Care must be taken to select the right Lasik eye surgeon for your specific needs and also to decide of Lasik eye surgery is the right procedure for you. The most important factor in successful surgery is to find an experienced surgeon, who will monitor your follow up care, and be there with you if you find yourself having any of these complications.
How Safe Is Lasik Laser Eye Surgery ?
About the time that people hit middle age, they start noticing a number of changes in their bodies and one of the changes that will often motivate people to see a doctor is when their vision is compromised. Considering that the baby-boomer generation has hit middle age and beyond, it is no wonder why Lasik laser eye surgery has become increasingly popular in recent years, as a way to counter the effects of vision deterioration.
Lasik vision surgery is a specialized procedure that provides vision correction for certain types of vision problems and conditions. Lasik is the term that is used as a “shortcut” for the full name of the operation, which is otherwise known as “Laser In-Situ Keratomileusis.” Other commonly heard terms for corrective eye surgery that is accomplished through the use of lasers instead of scalpels are: PRK, LASEK, custom Lasik, and Epi-Lasik.
There are three main vision problems that are easily corrected through Lasik laser eye surgery. These are near-sightedness, farsightedness, and forms of mild to moderate astigmatisms. With Lasik vision surgery, people are able to toss their eyeglasses, and the chance of losing or breaking them, into the trash forever. It can also eliminate the need for contact lenses.
A qualified and professional Lasik eye doctor will always make sure that a patient has a full and complete understanding of the process, before it is done. This gives them an advantage of not only being a patient but of being an informed consumer who has made a decision regarding their eye health and care.
While the risks of laser eye surgery are minimal, especially when compared to older methods of corrective eye surgery, it is in the best interest of the person considering such surgery to fully understand the possible complications and potential risks, as well as the cost of Lasik surgery.
The greatest advantage of a laser eye surgery procedure is that it is minimally invasive and does not involve the cutting of the covering of the eye, or cornea, with any type of surgical instrument. Instead, a thin layer of the cornea is cut with a laser beam and then gently pulled back, giving the laser eye surgeon the ability to then “sculpt” the corneal tissue to improve the vision. The thin flap is then replaced and the procedure is over.
After the Lasik laser eye surgery, patients notice an almost instant improvement in their eyesight. They can very quickly get back to their normal, everyday routines in almost all cases. Also, with Lasik there are no stitches to be concerned about and the patient will not even have to wear bandages. With all of this, some recipients of Lasik eye surgery even claim that the whole procedure could even be characterized as a divine wonder.

Refraction refers to how the light is captured by the cornea of the eye. Successful laser eye surgery has been shown to be effective in the treatment of myopia, hyperopia and astigmatism. After effectively treating these possible vision impairments, the patient often reports less dependence upon the use of eyeglasses or contact lenses.
The Surgical Procedure
Knowing about the surgical procedure is an important part of gathering information on laser eye surgery. Through the use of a surgical instrument called a microkeratome, a slight flap, that is circular in shape, is created on the part of the eye known as the cornea. This flap is then pulled back which in turn reveals the cornea.
The qualified surgeon then uses a laser to eliminate a portion of the tissue. This procedure results in the shape of the cornea being changed. This structural change of the cornea then allows for the light entering the eye to be refocused onto the retina. This entire process then allows for the vision of the patient to be improved. The surgical procedure is then completed when the circular flap is restored.
Advantages of Laser Eye Surgery
Your gathered information on laser eye surgery will reveal many advantages to this procedure. One of those advantages is the minimal amount of pain experience. In addition, results are almost instantaneous as the majority of patients report that their vision is improved the following day.
Take Care When Finding Your Laser Eye Surgery Clinic
These days there seems to be a good deal of “buzz” and excitement around the Lasik corrective eye surgery that is not only being widely discussed but is increasingly popular in many different crowds. While one can get caught up in the excitement of the promise of improved vision, one should always invest the time to be sure that a highly qualified eye surgeon is selected and that the choice of a laser eye surgery clinic is the best quality facility available.
Since laser eye surgery is an operation that will be making permanent changes to the cornea of the patient’s eye, and therefore to their vision, it is very important that this procedure is carried out at a reputable center. It is always a good idea when “shopping around” for a lasik eye center to not only consider the cost of Lasik surgery but also the reputation and background of the Lasik eye surgery center.
There are many aspects to be considered before selecting a laser eye surgery clinic where you will have your work done. Some of the most important of these points are: the overall cleanliness of the premises; how long the clinic has been in business; the education, licensing, and years of experience of the laser eye surgeons associated with the facility; the aftercare program that is offered; and finally, the training and experience of the support staff.
It is also a great idea to check with the local and state agencies that oversee such clinics. If there have been any serious problems with the results of a Lasik vision procedure, then the laser eye clinic will most likely have received complaints. You can check with your state agencies and also with the Better Business Bureau for any type of adverse events that might have happened in connection with that business.
As well, check on the track record of the Lasik eye doctor who will perform the procedure. As an additional step in due diligence, the patient can also check on the reputation of the administrator of the clinic, who in most cases will also be a certified laser eye surgeon. This is important because the director of an eye surgery clinic will be overseeing all operations and should also have a sterling reputation.
There are many large and well-known hospitals which now have an eye surgery clinic on the premises. For some people, this association with a highly reputable hospital gives them an additional level of security and confidence in the quality of care that they will receive, both in preparing for their corrective optical surgery and in the after Lasik eye surgery recovery.
However, in most cases, a laser eye surgery clinic that is part of a major hospital will be more expensive than a smaller, independent Lasik clinic. In general, the cost of Lasik eye surgery may be covered by your optical insurance coverage, at least in part, depending on the condition that needs to be corrected. Check your policy or consult with your insurance carrier is to be sure.
Sceptical About Laser Eye Surgery? Learn The Basic Facts And Clear All Your Doubts
Sam was a famous boy in our school. No he was not great at any kind of sports, also it never occurred to any of our teachers that Sam was academically promising. Nor had anybody ever heard or saw him taking part in any kind of extra curricular activities. You might be wondering, then why on earth the boy was famous in the school! Well, he was famous, or should I say made famous by his oversized and thick glassed spectacles. We never met since we had left the school in mid- 1990′s until recently, and believe me it came as quite a shock! Where has gone that bespectacled boy, whose eyes seemed to get lost for ever in the numbers of his thick glasses? Before me stood a new man altogether, smart, handsome and most importantly full of confidence.
Yes, this is what a laser eye surgery can do for you. It can transform your personality, it can enhance your looks, and it helps you to get rid of dependence on sight corrective devices, it promises you freedom to view the world as you wish. Well, there are differences of opinions regarding the result of the surgery. But use your common sense and judge for yourself. Why is it that millions of people in the USA are bidding good bye to their spectacles and undergoing laser eye surgery? The prices of surgery also came down only to indicate their soaring popularity. So definitely people are getting benefits from the procedure. Let us examine, what are these benefits?
The benefits from various types of laser eye surgery are obvious and extensive. These surgeries are aimed at correcting mild to moderate refractive errors of your eyes which are more commonly known as myopia or nearsightedness, hyperopia or farsightedness, and astigmatism or distorted vision. And the best thing about this surgery is that it is a permanent correction. Thus the cosmetic and utilitarian value of laser eye surgery is beyond imagination.
Currently, there are three options available if you choose to correct your vision through laser surgery. Among them is PRK or photorefractive keratectomy, being the oldest as well as simplest the reshaping of the cornea takes place with the help of computer-controlled beam of laser. LASIK, the acronym for laser in situ Keratomileusis is a complex procedure targeted at all degrees of nearsightedness. Here a surgical blade called microkeratome is used to curve out a flap from corneal tissue. After removing the tissue beneath it, the flap is replaced back. The third option is that of EPIFLAP or LASEK, where cornea is revealed by partial removal of epithelium and after the cornea has been gently reshaped, the epithelium is replaced back to its place.
So now you can understand how laser eye surgery works. If you are scared thinking the procedure might be painful, you are mistaken. You can also get back to your normal routine within three days time. And the most interesting thing is the time. It takes just about 15 to 40 seconds!
Thinking about the risk factors? Can you find any kind of surgery, where the surgeon does not warn you about the probable risk factors? In this case you can avoid risks by asking your doctor whether you are right candidate for laser eye surgery. Maybe some time you will get dry eyes or glare around lights at night, but the benefits you get from the surgery are much more valuable than these little inconveniences of life.

Amazing Laser Eye Surgery
Laser eye surgery is a modern miracle for many. Thanks to this advancement in vision correction there are so many people who now have perfect eyesight and have been able to throw away their glasses and contact lenses and live a more carefree life.
It’s amazing to think of how far laser eye surgery has come since it’s beginning over 4 decades ago. Lasers can now accurately change the shape of the cornea to correct the focus and help you see more clearly.
LASIK eye surgery results can be amazing, but it is still surgery and there are risks involved and potential complications so you should take the time to learn all you can about LASIK before opting for the procedure. Even so, laser eye surgery has become more important year after year and with technological advancements there are now several types of LASIK that can be utilized to correct your vision. Many people feel that the potential benefits of laser vision correction far outweigh any possible complications.
As a patient you’ll find that LASIK is not painful, but it can be uncomfortable and even frightening for some. This is because you are kept awake during the procedure and your eyes are held open artificially. You will need to continue to stare into the buzzing laser and this can frighten some patients.
In the past the initial flap in the cornea was created using a metal scapel, but that has changed as well with the introduction of IntraLase and now the entire eye surgery can be done just with lasers. This is a comfort to many who were really freaked out by the sight of the metal blade coming towards their eye. IntraLase is also much more precise that the older bladed cutting method, which helps to cut down on complications.
After creating a flap in the cornea the LASIK laser is used to reshape the cornea and improve the focus of the eye. It has been compared to adjusting the focus on your camera lens. Reshaping the cornea helps it to focus light properly and thus improves the vision, often dramatically.
It’s best to consult with an eye surgery clinic or physician to discuss the laser eye surgery procedure further and see what your options are. They will be able to advise you if you qualify for LASIK and will be able to give you costs and financing options. Trust me, it’s a great feeling on the day you no longer need to wear contacts or glasses.
Clarify Your Understanding On Laser Eye Surgery
It seems that just about everywhere you turn these days people are talking about laser eye surgery. And, even while it is being mentioned in different types of media and discussed between people, there are many left to wonder exactly what this high-tech procedure is and what kind of vision problems it can successfully correct. Following is some basic information about this corrective eye surgery, which can serve as an introduction to the topic.
The most common type of laser vision surgery is called Lasik eye surgery and it does have some aspects that set it apart from other types of surgery to correct vision problems. The main distinction is that the Lasik procedure does not require the doctor to actually cut the cornea surface. This means that there are generally few complications with this kind of eye surgery and the risks to the patient and their vision is also very low.
The term Lasik is an acronym that stands for “Laser In-Situ Keratomileusis.” By utilizing a laser light, the surgeon is able to carry out the corrective procedure while leaving the surface of the eye lens completely intact and unharmed. This type of laser eye surgery provides a huge advantage over the older, traditional methods which often caused damage to the lens surface through the use of surgical instruments.
Lasik laser eye surgery has become one of the most widely used and popular methods to correct vision problems. This corrective eye surgery is best suited for those who are near-sighted, who are far-sighted, and for those who have an astigmatism, which are all vision conditions that affect a significant portion of the aging, baby boomer population.
Lasik eye surgery is able to reshape the cornea of the eye, which is the outer layer, or covering. When this is done properly by the Lasik eye doctor, the light which passes through the cornea is better focused onto the retina at the back of the eye, which is essentially where the vision “signals” are interpreted.
In addition to being overwhelmingly effective, another advantage of this remarkable procedure is that the patient who undergoes the treatment experiences very little discomfort. Also, after the Lasik corrective eye surgery, the vision is noticeably improved almost instantly and there is no need to have the eyes bandaged, nor is there any need for stitches.
These various factors all combine to provide the patient with a fast recovery and with an extremely low risk of any kind of complications or infection, which were actually quite commonplace before laser eye surgery became available. The cost of Lasik surgery can be at least partially covered by many vision insurance plans. However, even for those who do not enjoy such coverage, the cost of Lasik is quite minimal compared to the enormous benefits they receive from the procedure.

How Laser Eye Surgery Works ? Lasik and Photorefractive Eye Surgery
People with eye-related problems are becoming more and more interested in laser eye surgery and its benefits because this is known to be the most exciting ophthalmologic procedure.
To be more precise, this is a refractive eye surgery that can correct all types of refractive errors such as: astigmatism (distorted vision), myopia (nearsightedness) and hyperopia (farsightedness).
Even if the medicine offers various types of surgical techniques for correcting refractive errors, the laser eye surgery was labelled by the American Academy of Ophthalmology the most technically advanced and precise one.
The excimer laser was the first laser ever approved for eye surgery and it’s used to correct myopia. Now, this laser is used in two different procedures: Laser in situ Keratomileusis (LASIK) and Photorefractive Keratectomy (PRK).
Photorefractive Keratectomy (PRK)
The surgeon maps and measures the patient’s eye before the procedure in order to analyse the problem. Then, he uses a few local anesthetic eye drops and reshapes the cornea eliminating tiny amounts of tissue from the outer surface.
Next, the doctor uses an ultra violet beam of light and cuts notches the size of human hair. Each pulse of light can remove a 39 millionth of an inch of cornel tissue in only 12 billionths of a second.
According to same studies, only 5% of the patients still use permanent glasses after the surgery while 15% need visual aids only when driving.
Laser in situ Keratomileusis (LASIK)
The LASIK procedure is more complicated than PRK but it’s a solution for solving all types of myopia.
The surgeon uses the Microkeratome to cut a corneal tissue flap in order to replace it. Everything depends on the doctor because with LASIK he has to make a very precise incision.
The patient only feels a little discomfort and sometimes an irritation but those won’t last too long. In most cases, the patients returned to their normal life in only two or three days.
With LASIK there can be only one side effect and that is occasional glare at night.
Anyway, everyone should know that even if the results are said to be permanent, the age can influence the final results and in some cases the doctor may even suggested re-surgery.
Corrective Laser Eye Surgery is Affordable and Reasonable
Dry eye or dry eye syndrome is found to be very a common occurrence especially in the older generation that may affect millions of people though it seems that more women than men are afflicted by it. Dry eye is a condition in which the person does not have enough tears in the eyes that would cause the eye to stay moist and comfortable as well as clean. This is a defect in the eye that may be caused by laser surgery as the tear film which is composed of three layers with each component layer being dependent on the other for proper performance may get damaged.
Symptoms of dry eye condition are persistently gritty eyes, itchy eyes, burning sensation in the eyes and pain. The symptoms generally tend to get worse with each passing day and there may also be stringy mucus that may be seen in or around the eyes. The first line of treatment for dry eyes is to use lubricating eye drops or gels which can be bought over the counter. However, corrective laser eye surgery may be required to treat the aggravated dry eye and once the patient has been treated for the specific cause, corrective eye surgery may be necessary to correct faulty vision.
Advantages Include Affordability
The advantage of having corrective laser eye surgery is that it is quite affordable for everyone and its popularity among people is growing as it allows the patient to anticipate having good vision without recourse to using glasses or contact lenses as the incidence of people using laser eye surgery continues to grow. With positive feedback that emanates from those who have found corrective laser eye surgery to provide best results, more and more people are getting convinced that there are genuine benefits to this form of surgery. Some of the benefits of corrective eye surgery are that the procedure is affordable.
Corrective eye surgery owes its popularity, amongst other things, to its value for money and has been found to correct many of the problems that affect a person’s vision. It has also been used to treat cataracts, glaucoma, as well as macular degeneration and these are problems that often hinder vision in the elderly. Macular degeneration is one of the foremost reasons behind blindness in old people and corrective laser eye surgery would be able to treat macular degeneration though not cure it and symptoms may be controlled though the process, even though they may not be completely eliminated.
Who Can Have Laser Eye Surgery?
If you are dependent on glasses or contact lenses, you may wonder if laser eye surgery is an option for everyone. Many people today are rushing out and finding an eye surgery so they no longer have to wear corrective lenses, however, if you are not a good candidate for the procedure you may soon learn that the complications are not worth the risk.
Before you make that decision, you should look at everything that is involved including the number one thing to know. Is the eye doctor licensed to perform laser eye surgery? There are not as many licensed ophthalmologist as you might think. Ask to see the certificate to ensure they know what they are doing and learn how many times they have performed the procedure. It would also be in your best interest to find out how many times they have performed the procedure with blades and without blades.
Learn what risks are involved and if your own expectations will be met with laser eye surgery. Many people that have this procedure learn that they still have to wear glasses for night vision among a few other vision problems. Just because this procedure helps you to see clearer, does not mean that you will have 20/20 vision. Be prepared for less than perfect vision.
Laser eye surgery is expensive; however, if you divide it out over the years it will amount to less than purchasing glasses or contacts each and every year. Talk with your insurance carrier, in some cases; they will cover part of the costs.
Individuals under the age of 18 cannot have laser eye surgery. The eyes are still developing and do not have refractive stability yet. Pregnant women, breastfeeding mothers, persons with diabetes, or those taking medications that cause variations in vision are not good candidates for this procedure.
The best way to learn if you are a good candidate is to discuss this with your health care provider before you visit your eye doctor or ophthalmologist. Individuals that have conditions such as shingles or herpes around the eyes should give this important information to the eye doctor as well as any other health problem associated with the eyes such as any eye disease, ocular hypertension, glaucoma, keratoconus, or other eye surgeries.
Just remember, laser eye surgery is surgery! With all surgeries, even elective surgeries there can be complications such as infection and other diverse reactions. The best thing to do is to discuss your expectations and your concerns with your doctor and your ophthalmologist.
Laser eye surgery
Patients undergoing LASIK (acronym for laser assisted in situ keratomileusis) will require little time to heal and benefit from reduced discomfort, which are two desirable postoperative conditions.
Recently, more and more people have started to seek out as an alternative to wearing glasses or even contact lenses, correcting their refractive disorders surgically. The procedure is often performed with the patient lying consciously on the table, the only anesthetic being administered locally in the form of eye drops. Once the doctor has made a small flap in the cornea, the next step is to apply the laser and correct the refractive disorder. The flap will then be put back in place and the procedure over. However, one has to understand that the most difficult part of is actually creating the flap.
Before creating the flap, the doctor will have to prevent the eye from moving. The moment this objective is achieved, the flap will be created using a special instrument generally known as microkeratome. The only discomfort the patient might feel will be during the lifting of the flap but this is not a case for all patients. The next step is to remodel the cornea using the laser, most patients experiencing a blurry vision and become disoriented. After this treatment is performed, the flap returns to its original position and the doctor will verify if everything is alright.
has a wide range of benefits but it is important to understand that there are certain complications associated, just like other medical interventions. LASIK surgery might cause one to have dry eyes, suffer from abnormal vision and even increased sensitivity to light. Other potential complications include debris under the flap made in the cornea (which is likely to cause infection), the appearance of astigmatism (in patients who did not suffer from that particular refractive disorder) and the dilatation of the cornea. The complications can be classified according to the moment they appear, meaning before, during or after the surgery.
Before undergoing such an invasive procedure, the doctor should perform a thorough medical investigation and obtain as much information as possible about the patient’s medical history. There are many factors that contribute to the outcome of the , starting with the condition the patient is suffering from and his/her age. Patients are recommended to stop wearing contact lenses a few weeks before the surgery, thus reducing the risk for the cornea to become vascular during the intervention.

Laser Eye Surgery Could Improve Your Sporting Life
If you wear glasses, the chances are that sporting interactions in your daily life can be troublesome. Whether you play football in your local league or you’re an avid rugby watcher, it’s possible that your less than perfect vision may impede your ability to appreciate the finer moments in sports games. Even if you wear contact lenses when playing sports, problems can persist: your eyes could get dry and itchy at the crucial stages of a match, costing you or your team a much needed victory. Or you might lose a lens during play and have to spend hours searching for it among the grass or mud. If you feel that these restrictions are a significant factor in lowering your quality of life, it might be time to think about laser eye surgery. In the past, people may have considered such surgery a dramatic option to take towards optical improvement. However, with millions of successful LASIK or LASEK procedures being performed around the world, many are coming to realise that laser eye surgery is within reach and could have an impressive effect on your eyesight – something that could be invaluable if you enjoy an active sporting lifestyle. For instance, if you’re planning a career in sports commentary or sports reporting, having great eyesight is likely to be crucial to the accuracy of your match reports. Whether you’re a recent graduate hoping to enter this field or you’re in your mid-40s and pondering a career change, considering having surgery on your eyes could have tremendously beneficial effects on your employability. What’s more, if you’re a keen golfer or tennis player with professional potential, but hampered vision means that you have to wear glasses or contact lenses, it’s possible that from having surgery you could help improve your game. And it’s not just mainstream sports players or enthusiasts that could benefit from laser eye treatments either. Competitive cyclists, for example, could perform much better if they’re better able to see that upcoming bend in the track from further ahead. Furthermore, if you’ve always been keen to try archery, shooting or any other sport that requires good aim – but you’ve been held back by poor sight – from having surgery on the eyes you could make those dreams a reality. While laser eye surgery offers clear benefits to sports players, reporters and general enthusiasts, it’s also important to be mindful of the potential drawbacks. Before making a decision to undergo the operation, make sure you seek professional advice from an optician; if you’re still unsure, a second opinion might be the best thing to set your mind at ease. Indeed, the experts will be able to offer you detailed advice on the best treatments, leading clinics in your area and, crucially, ascertain whether your eyes are compatible with the procedure. Once you’ve got all the information you need, you can go into your laser eye surgery operation with the peace of mind of knowing that, when you come out, your sporting life will be that much more enjoyable.
