Before the PRK procedure begins, the eyes are numbed with anesthetic eye drops. The surgeon then uses an excimer laser, with targeted laser energy, to reshape the cornea. The surgeon has complete control over the laser throughout the procedure, for a highly precise and customized result, designed to give each patient the best vision possible. The entire procedure takes only a few minutes to perform. Because of the potential for blurred vision for a time after PRK, the surgery is often performed on only one eye at a time, with the surgeon waiting to schedule the second eye until the vision in the first has adequately cleared.
After the procedure, the eyes are bandaged with a soft contact lens to protect the cornea. New cells will grow back over the next few days to replace the cells that were removed. The contact lens will be removed by the surgeon in a follow-up examination.
