ABSTRACT:
A surgical instrument for performing a peripheral iridectomy includes a housing having a needle portion and an internal hollow. Located within the housing are grasping means which can be moved by the surgeon to grasp the tissue of the iris and to be withdrawn so that the tissue is pulled through the aperture in the needle portion into the hollow of the housing. The tissue of the iris when pulled into the housing is directed through an aperture existing between a cutter mechanism. The cutter mechanism is then activated by the surgeon to cut a predetermined amount of tissue to thereby complete the iridectomy. The tissue cut remains in the housing.
