A stand for supporting a donor eye during the excision of a corneoscleral button or cornea disc comprises a base plate (1) presenting an upstanding spindle (7) upon which a main body (8) having an externally threaded cylindrical projection (15) is rotatably supported. A donor eye placed on an eye support block (17) lodged in the main body projection (15) is clamped by means of a clamping unit (30) comprising an internally threaded clamping cylinder (31) one end of which is screwed onto the main body extension (15) and a clamping ring which is screwed into the other end of the clamping cylinder (31). The main body can be locked to the spindle (7) by a locking pin (12) and the clamping cylinder (31) can be locked to the main body (8) by a thumbscrew (40). <IMAGE> |
