Abstract
A trephine for cutting a groove in the cornea of an eye comprising a fixation member and a shaft having first and second blades mounted thereon. The fixation member includes a bearing, and the shaft is receivable within the bearing. The fixation member can be affixed to the eye, and the shaft, when received in the bearing, is rotatable in the bearing so that the blades 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.
