Correction of preexisting astigmatism at the time of small incision cataract surgery

Abstract

To reduce preexisting astigmatism in patients having cataract surgery, paired keratotomy incisions of graded lengths were performed at the time of cataract extraction. Small incisions, made possible by foldable silicone implants, were used to make the correction more accurate. The results obtained in 48 patients are analyzed. It appears that this technique is safe, quick, and helpful in reducing preexisting astigmatism.
