But what exactly is LASIK eye surgery?

What happens during LASIK laser surgery is that thelasers correct refractive errors in the cornea. Thelaser perfectly controls the tearing of the cornealtissue, thereby reshaping the cornea and changing itsfocus. LASIK surgery follows a simple two step process:

1. A slight, thin flap of tissue is created on theoutside layer of the eye or cornea. This flapencourages healing and provides comfort on the way tobetter vision.

2. The surgeon folds open the flap on the innercornea to correct the eyesight. Once this is done, theflap is closed to its original position and sealedwith stitches.

The word LASIK refers to Laser-Assisted In SutuKeratomieusis, a process which is characterized by thereshaping of the cornea to refract light in the lens.While LASIK eye surgery is by no means perfect, it isa very viable and increasingly safe surgery.
