LASIK, LASEK and LASAK revealed

The most popular surgery method is LASIK. The reason is that it is effective, gentle and fast. Complications when using LASIK are very rare. So LASIK will be a good 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.

Because the operation is made on the surface of the corneas, the LASEK surgery is especially good, if you have thin corneas. It is also better, if you suffer of dry eyes.

LASAK is the most modern method of eye surgery. The flap, which is cut off, is thinner than when using the LASIK method. Because of the saved corneal tissue, it is a great method if you have 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.

The surgery result can be improved even more, if the methods are used in combination with the Wavefront method. The irregularities on the corneal are measured with a special instrument, and a kind of topographic map is constructed. Finally a computer calculates the correct settings for the laser surgery based on the specific eye.

The Wavefront method gives a more unique measurement of the eye. That gives an improved result and a better night sight. Astigmatism in the eyes will also be corrected in a better way.

The cornea is aspheric and not ball-shaped. The newest method called Aspheric treatment considers that when operating. The method is used in combination with one of the three surgery methods.

Using the normal surgery methods the eye will be more ball-shaped, which might give a bad night sight and reduced contrast ratio. Using the Aspheric treatment the surgery will create a larger curve in the central part of the eye. The result is better sight; which in some cases can be even better than when using glasses or contact lenses.
