Abstract
An apparatus and method for forming a circularly or substantially circularly shaped pocket between layers of a live cornea, and then, expanding the pocket to form a flap-like layer at the front of the live cornea which is pivotally attached to the remainder of the cornea by a flap connecting section. The cutting tool of the apparatus preferably has a circular or substantially circular cutting portion which is inserted into the cornea and reciprocated to form the pocket. Suction is applied to the front surface of the cornea to stabilize the cornea during the pocket forming process.
