Probability of Lasik Resulting in 20/20 Vision

Lasik eye surgery is one of the major medical advancements of this century. Those who were once unable to see except for glasses with single vision or bifocals are now able to see perfectly after the procedure. People with astigmatism so severe that they could not wear contact lenses can also be helped by Lasik. The probability of Lasik resulting in 20/20 vision is not always what eye doctors advertise, however. Yes, it is possible to get 20/20 vision with the surgery, but it all depends on how well you see before the procedure.

There is no database that lists the results of this surgery, so the probability of Lasik resulting in 20/20 vision must be based on individual tests and claims made by eye doctors. According to a recent report published by the American Association of Professional Eyecare Specialists, the results of Lasik surgery are 55.3 per for 20/20 vision after the procedure. Around 92.6 percent of those who have Lasik will have improved vision of 20/40 or better, according to the report. This could mean that a person has much better than 20/40 vision, but not quite 20/20 sight. Patients with severe astigmatism or myopia do not usually get 20/20 vision results, but their uncorrected vision will improve.

Other estimates of the probability of Lasik resulting in 20/20 vision are a bit different. Some reports say that those with severe myopia and astigmatism will not get as favorable of a result, but it will be very close at around 94% getting 20/40 vision or better.

It is important to keep in mind that although many people think that 20/20 vision is perfect, there is no such thing as perfect vision. Having 20/20 vision means that a person can see letters on the commonly used letter chart from a certain point. Many people have better than 20/20 vision. For those who have poor eyesight and do not like to wear cumbersome eyeglasses, Lasik can certainly improve their vision greatly.

Lasik surgery, like all surgery, is not without risks and possible complications. The risks are minimal, and if there is a problem during surgery, it can usually be fixed. There are some complications, however. These include problems that can occur after the eye surgery, such as dry eye, hazy vision, night glare, blurry vision, or double vision. Another factor to consider is that some people may have better results on a vision test, but they may still have blurry vision or one of these complications. Even though their vision may be improved in reading a testing chart, it could be worse if they now have peripheral vision that is blurry or other problems.

A new type of Lasik surgery promises to deliver even better results to patients, but it does not lessen the chance of complications after surgery. It is Wavefront technology that has been used for around two years. Wavefront can provide better results than just Lasik surgery alone. An even better new method that eye doctors are beginning to use is Waverfront Lasik surgery with iris registration. Iris registration tracks the movement and rotation of the eye. It moves with the iris when the iris moves and matches the eye’s movement for even better laser results. Waverfront eye surgery alone produces results of 20/20 vision in around 95 percent of patients, while Lasik with iris tracking gives 99 percent of patients 20/20 vision. Eye surgeons have seen complications after Waverfront Lasik similar to those from traditional Lasik surgery, such as dry eye. Although there are not many published results from this procedure, some doctors are reporting less cases of night glare, blurry vision, double vision, and problems with night lights.
