Patent ID: 7892283

Claim:
An apparatus for inserting an intraocular lens (IOL) into an eye, the apparatus comprising: a load chamber for receiving an IOL and including a hollow passage with an ejection port through which the IOL is passable and which is defined as having a longitudinal axis with a distal direction toward the ejector port and a proximal direction away from the ejector port; and a handpiece including: a body member including a boss; an injector rod that is receivable by the body member and that is longitudinally movable within the hollow passage, the injector rod having a distal portion adapted to contact the IOL when positioned within the hollow passage; and a drive mechanism that longitudinally oscillates the injector rod in the body member when a rotational force is applied about the longitudinal axis in a single direction, wherein a drive assembly moves the injector rod a plurality of times in a distal direction by a first longitudinal distance and then in a proximal direction by a second longitudinal distance that is less than the first longitudinal distance.
