A new corneal trephine.
A new corneal trephine, using suction and disposable razor blades, comprised two cones, one revolving inside the other. A slide mechanism was attached to the inner cone that inclined a disposable razor blade either vertically or at 20 degrees, assuring clear view of either side of the incision and more accurate centering. The effective diameter of the cut was varied continuously from 8.5 to 2.0 mm.
