Anterior radial keratotomy experience in 600 cases of myopia.

Surgical results of anterior radial keratotomy in 1,200 eyes are presented. Of the eyes, 55% had an unaided visual acuity of 6/9 or better six months after surgery. An average of 1.90 D of myopia was corrected in these cases. It takes six weeks for the refraction to stabilize and to know the final success of surgery. There was no statistically significant influence of age or sex or preoperative refractive error on the amount of surgically induced change in refraction. The extent of myopia corrected is directly proportional to the change induced in the radius of curvature. The operative and postoperative complications were minimal and did not endanger vision.
