laser eye surgery, a laser device is used to make changes in the formContour of the cornea. An excimer laser is often used for this process, this creates an ultra violet light, which vaporizes the tissue is undesirable. This procedure would change the contour and shape of the cornea to correct most mild to moderate refractive errors.

The most common laser eye procedures are keratectomy, PRK (Photo Refractive), LASIK (laser assisted situ keratectomy), recently developed LASEK (laser epithelial keratomileusis) andthe Epi-LASIK.

Then a laser is used to evaporate within the corneal tissue, this vision is to improve its shape, which lead to good. Once the tissue enough to be removed, the flaps return to its original position. cure in this case faster than PRK.
