ABSTRACT:
This invention is for a surgical method for modifying the curvature of the cornea. The method involves making a semicircular lamellar cut on the cornea to form a superficial layer which remains connected to the cornea in a superior zone so as to form a flap. The superficial is raised to expose the underlying surfaces which are subjected to the desired ablation. The superficial layer is then replaced over the underlying surface so as to adhere. By forming a flap with the connecting hinge region in a superior zone, the flap which is raised during the operation and then replaced will be smoothed over the remaining part of the cornea under the effects of the blinking movement of the eyelid and by gravity. This encourages the distension and centering of the superficial layer and enhances the effects of the ablative treatment. The method of the invention also provides greater ease and convenience to the surgeon performing the method.
