Photorefractive Keratectomy (PRK) is the forerunner of Lasik and is still used as an alternative today. If a potential patient has thin or damaged corneas or too large pupils, this procedure may be the only way to proceed.
During this procedure, the eye surgeon actually removes layers of the cornea’s surface cells (called epithelium cells) to help reshape the eye. Additionally, this procedure uses a laser to gain access to the stoma via the cornea. Unlike traditional Lasik, this procedure does not create a flap in the cornea.
As a result, PRK normally has a longer recovery time when compared to Lasik.
