PRK – Photorefractive Keratectomy

PRK modifies the cornea to the correct vision. The process is completely different from lasik.  Here an excimer laser sculpts an area on the eye surface (epithelium) unlike Lasik, where the surgeon cuts a flap from the cornea. The excimer laser is more accurate than the blade used in Lasik and it removes a microscopic corneal cell layer without damaging the adjacent cells, resulting in better results and avoiding the risk of complications.

After the PRK surgery, the patient will have a bandage contact lens placed on his eye. This helps in the healing process. In addition, the surgeon will prescribe pain relief medication for a couple of days after the surgery. Like the Lasik, you should know everything about it before deciding to do it. Sit with your surgeon and try to have all the information about the surgery.

There is no pain felt during the surgical procedure, neither in PRK nor in Lasik. A faster recovery is obtained with Lasik than PRK. Like any other surgery, PRK has side effects and complications. However, serious complications are very rare and depend on the chance to develop the complications, and this can be expected pre operatively through the examination and screening done before the surgery. Infection is the most common complication, but it is a relative one, as the patient eliminates it by using antibiotics.  However, there may be some risk of delayed healing of the corneal tissue which with medication is usually treatable.
