<p>It consists of a surgical cutting device for cutting and marking of the cornea or its layer for unique positioning of the obverse and reverse sides during a consequent transplantation procedure, namely during the procedure of a sc. lamellar endothelial transplantation. The working part of the cutting device (1) is formed by a cutting edge (2) at its end. The cutting edge (2) of the tubular body (la) with the cutting device (1) is equipped with asymetrically shaped and/or asymetrically arranged notches (2a) for marking the donor membrane for its proper positioning during the consequent transplantation when the upper and lower sides of the graft are uniquely distinguishable by the edge relief on its periphery.</p> |
