Improved stand for the donor eye for corneal grafting.

A STAND, developed at this hospital, for holding the donor eye while a corneal graft is trephined and dissected is particularly useful for lamellar, annular, or segmental grafts, especially where direct sutures are used (Fig. 1). Essentially this is a modified Tudor-Thomas stand, so designed as to rotate on a plinth carrying a spring-loaded metal ball (Fig. 2A), which engages consecutively into four notches placed at 900 intervals at the bottom of the stand (Fig. 2B). By this means the stand can be engaged at four positions 900 apart during one complete revolution. Disengagement from a "stop" requires no effort so that the entire mechanism works smoothly and efficiently. The plinth also has a pair of handles (Fig. 2c, c) with separate "lifters" for lifting it out of the sterilizer. B
