Astigmatic Keratotomy

AK is an incisional procedure used to correct mild to moderate amounts of regular astigmatism. Astigmatism occurs when the cornea is shaped more like a football than a basketball. The cornea with astigmatism typically has a steep curve in one quadrant and a flatter curve in the opposite quadrant. Incisions are made with a diamond scalpel, preset to a precise measurement, in the periphery of the cornea in the quadrant where the steepest curvature occurs. These incisions allow the cornea to relax and thus take on the shape of the flatter quadrant. AK is often used in conjunction with both PRK and LASIK when an individual has a high amount of astigmatism. The AK can be performed either prior to or after a laser procedure.
