ABSTRACT:
An ophthalmic surgical instrument (10) for cutting the lens (76) of an eye (70) includes first (12) and second (14) handle members which are interconnected for movement between an open position and a closed position. A wire loop (20) extends from the first end (12a) of the first handle member (12). A plate member (22) is interconnected to the first end (14a) of the second handle member (14) and is disposed adjacent the wire loop (20). In the open position of the handle members (12, 14), the wire loop (20) is spaced apart from the plate member (22) to receive the lens (76) therebetween. In the closed position of the handle members (12, 14), the wire loop (20) contacts the plate member (22) to cut the lens (76) disposed therebetween as the wire loop (20) presses the lens (76) against the plate member (22) to thereby cut the lens (76 ).
