What is photorefractive keratectomy (PRK)? Photorefractive keratectomy (PRK) is a procedure used to reduce the need for corrective eyewear by reshaping the cornea of the eye with a laser, thereby changing the way the eye focuses light. An excimer laser is used to ablate (remove) a thin layer of the cornea, changing the cornea's refractive (focusing) power.
How PRK Differs from LASIK. Whereas LASIK involves the creation of an epithelial flap on the topmost part of the cornea, PRK involves the removal of the epthelium in order to reshape the cornea. This improves the way that light passing through the eyes focuses on the retina, the light-sensitive tissue located at the back of the eye.
