PRK Eye Surgery (Photorefractive Keratectomy) is an elective, outpatient laser vision correction procedure to improve vision and reduce or eliminate the need for eyeglasses or contact lenses. In the PRK laser vision correction procedure, the laser surgeon utilizes the excimer laser to reshape the curvature of the eye for patients with nearsightedness, farsightedness, and astigmatism.
Photorefractive Keratectomy has been performed since 1986. Prior to LASIK, PRK was the most commonly performed laser vision correction procedure. PRK differs from LASIK as no flap is created during the PRK procedure. PRK may be suitable for people with larger pupils, thin corneas, have other corneal issues or dry eyes.
