Abstract: A method of repairing a cornea of an eye. A donor material of living tissue in the shape of a partial sphere having an exterior Bowman's membrane of living tissue, is first die cut to define an outline configuration including a central extent and a plurality of tabs extending outwardly therefrom. The tabs are then shaved to remove substantially all of the donor material therefrom leaving substantially only the Bowman's membrane. The eye to be repaired is then punched to form a central aperture in the cornea having a size and shape essentially that of the central extent of the donor material. A plurality of pockets are incised from the central aperture into the cornea, the pockets being positioned and sized and shaped to receive the respective shaven tabs when the central extent is positioned within the central aperture.

Abstract: A tool and a method for preparing a donor material used in sutureless corneal transplants uses a first cutting portion to prepare a donor blank having tabbed portions extending outwardly radially. A second cutting portion is used to cut the central portion of the blank. The tool is used as a guide member for the second cutting portion. In one embodiment the tool has slits laterally defined therethrough which allow the tabbed portions of the donor material to be thinned to a desired thickness using a scalpel. In an another embodiment the second cutting portion is a round trephine which is used to simultaneously trim each of the tabbed portions.
