The first edge is shaped to form a sharp cutting edge extending from the point (42) a predetermined distance shorter than the distance from the base of a surgical incision to Bowman's membrane, a portion of the first edge adjacent to the sharp cutting edge being dull relative to the cutting edge.</p> |
