ABSTRACT:
A trephine for cutting a groove in the cornea of an eye comprising a fixation member and first and second shafts having blades mounted thereon. The fixation member includes a bearing, and the shafts are sequentially receivable within the bearing. The fixation member can be affixed to the eye, and the shafts, when received in the bearing, are rotatable in the bearing so that the blades carried by the shafts can make cuts in the cornea. By making cuts in the cornea which intersect, a segment of the cornea can be removed to provide the groove.
