The Kavanagh Pre-Chopper features a broadened platform tip to effectively insert into the lens nucleus and securely split the lens into the desired segments. Micro-incision tubular instrument shaft configuration allows insertion through small wounds. The instrument incorporates a round squeeze action handle which allows for ease of hand placement and rotation of the instrument for passage through the cataract wound. The Kavanagh Pre-Chopper may also be used as a nucleus cracker.
