Abstract
A hand supported instrument for assisting in the formation of ophthalmological incisions includes a plate member which has a bottom surface adapted to rest upon the surface of the human eye. The bottom surface is curved so as to conform to the normally curved surface of the human eye. A longitudinally-oriented slot extends through the plate so as to serve as a guide for a knife blade intended to be positioned in the slot. The plate member also has a top surface which is spaced from the bottom surface by the thickness of the plate. In this manner, the top surface serves to limit the penetration of the knife blade through the slot. The thickness of the plate will vary from a minimum at one end of the slot to a maximum at the other end of the slot. In this fashion, the plate will serve as a template to control the depth of incision formed by the knife blade extending through the slot. A handle is connected to the plate at the thicker end of the plate so that it can be held in position for use.
