Photorefractive keratectomy (PRK) is a type of refractive surgery intended to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Unlike LASIK, PRK does not involve creating a flap in the cornea. Instead, the epithelium (the outermost layer of the cornea) is removed to allow the excimer laser to access and remodel the corneal surface.
