PRK, or photorefractive keratectomy, uses a specialized awesome laser beam, called an excimer laser, to get rid of excess corneal cells. The removal of this tissue remedies the form of the eye to ensure that light going into the eye could be effectively focused on the retina. The outer surface layer called the epithelium, is gotten rid of to reveal the underlying corneal cells. When this tissue is exposed, the excimer laser is made use of to improve the cornea.

This permits the specialist to gently tease the epithelium flap out of the way to subject the underlying cells. An excimer layer reshapes the eye under the flap to fix any type of refractive mistakes, after which the flap is changed over the treated cornea. As with LASIK, the substitute of the flap in LASEK accelerate the natural healing procedure as well as offers to reduce discomfort resulting from the treatment.
