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.
