A New Surgical Technique for the Correction of Hyperopia After Radial Keratotomy: An Experimental Model

Abstract

Cadaver eyes were used to develop a suture technique that permits controlled adjustable steepening of the central corneal curvature over a wide range. The technique consists of placement of a 10-0 Mersilene monofilament suture at a 30% to 50% depth of the cornea in a circumferential, purse-string fashion. Corneascope photographs document the effectiveness of the procedure as applied to radial keratotomized eyes. By utilizing this procedure in conjunction with a modified radial keratotomy technique, a method of steepening the cornea in a virgin eye is presented. The potentially broad applications of the procedure are discussed.
