ABSTRACT:
A device for cornea operations on the human eye is composed according to the invention of various instruments and auxiliary implements in such a way that the transplantation of a disk-shaped part of the cornea (perforating keratoplasty) can very largely be carried out automatically by machine, surgical manipulations carried out by hand being almost eliminated. On a three-dimensionally adjustable carrier, an axis adjustment instrument (17), a trephine (18) and a transplanter (19) are fitted in such a way that these instruments can selectively be brought into coincidence with the visual axis of the patient and moved to a pre-adjustable height. Preferably, the carrier comprises an auxiliary carrier (8) and a rotary plate (11) which is pivotable about a horizontal axis (12) on this auxiliary carrier. This rotary plate carries the instruments. An eyeball holder ring (14) adjustable in height and a manipulator (15) as well as a cartridge changer (16) are immovably fitted to the auxiliary carrier (8). The instruments and auxiliary implements are described in detail. The device as a whole can be operated by means of a control panel (20). The functions and program sequences are electrically controlled, can be stored and are visually displayed on a monitor (21). (FIG. 1 for reference).
