Photorefractive keratectomy (PRK) is a common laser vision correction procedure which is used by many ophthalmologists across the country. This procedure also utilizes the excimer laser to reshape the cornea (just like in LASIK procedures), but instead of lifting a flap to reach the sub-layer of the cornea, the outer layer is removed completely. This skin layer regrows in about 3 to 5 days. Our doctors will generally have you wear a contact lens (like a bandage for your eye) for a few days postoperatively to shield the newly treated surface from irritants, even your own blinking eyelid! The bandage lens helps keep you more comfortable as the removed layer regrows.

Because the epithelial layer of the cornea is removed in PRK, good vision takes longer to return than with LASIK. However, sometimes PRK is recommended by our surgeons because ultimately it can lead to better long term results.

Other than the flap which is not done for PRK, the other elements of the surgery and recovery are the same. Please read the sections on this website about LASIK for other information about the actual procedure.
