Choose the Right Eye Surgery Method
There are basically three eye surgery methods. They are all called almost the same. They are: LASIK, LASEK and LASAK. In addition there are two other methods to improve the result: Wavefront and Aspheric treatment.
Because it is fast, gentle and effective, LASIK is the most popular method. There are very few complications, so it will be a good eye surgery method for most people.
The LASIK surgery method is a painless operation, and in only a few hours, the sight will be improved. One of the few sight effects are dry eyes. The surgery method can be used for most eyes; from -12 to +3.
For people who are only a little long-sightedness or near-sightedness (from -2 to +2), the LASEK surgery is a great method.
If you have thin corneas the LASEK surgery is a great method, because the laser surgery is made on the surface of the corneas. It also more gentle, if you have very dry eyes.
LASAK is the newest type of eye surgery. Compared to a normal LASIK surgery, the flap, which is cut off, is thinner (saving the corneal tissue). That means it is a good method for people with thin corneas.
Other advantages of the LASAK surgery are a shorter time of healing and lesser risk of complications. There is also no pain after the operation, and the eyes will not be so dry. Finally the sight is steadier.
By using the Wavefront method in combination with LASIK, LASEK or LASAK, the result can be even better. With the help of a special instrument the irregularities on the corneal are measured, and a range of calculations are made on the computer. The result is a kind of topographic map, which is used for setting the laser exactly for the specific eye.
By using the Wavefront method, the result will be better because of the unique measurement of the eye. The method does also give a better night sight and astigmatism in the eyes will be treated with a better result.
Aspheric treatment is the newest step in eye surgery; and is used in combination with LASIK, LASEK and LASAK. The treatment takes into account that the cornea is not ball-shaped; but aspheric.
When using LASIK, LASEK or LASAK without Aspheric treatment, the eye will be more ball-shaped. That gives a reduced contrast ratio and a bad night sight. If the Aspheric treatment is used, the curve in the central part of the eye will be made larger (as it is in an untreated eye). This gives a much better result; sometimes even better than with contact lenses or glasses.
