Abstract
A new surgical technique to correct hyperopia by steepening the central corneal curvature was performed experimentally on the eyes of rabbits. After X-shaped incIsIOns at four quadrants of the mid-peripheral cornea, four circumferential interrupted sutures with nearly full depth reaching to Descemet's membrane were performed across the incIsions. The knots were tightened in order to shorten the cornea in the direction of the suture and eventually to shorten the circumference of the mid-peripheral cornea, which, in turn, induced a forward bulging of the central cornea. Twenty-three eyes of 12 albino rabbits were divided into group A (7 eyes) with 4mm of optical zone, group B (9 eyes) with 6mm of optical zone, and group C which, as the control group, consisted of 7 contralateral eyes of gorup A without any incision or suture. There were significant changes (p
