Patent ID: 8702795

Claim:
An intraocular lens insertion device, comprising: a main body with a lens advancement axis extending therethough; a rod that defines a length and is movable along the lens advancement axis in a forward direction from an initial pre-use position to a fully extended position; a plunger that defines a length and is movable relative to the main body along the lens advancement axis with the rod in the forward direction from a return position, which defines a proximal-most position of the plunger, to a push-out position, which defines a distal-most position of the plunger, and is movable relative to the main body along the lens advancement axis away from at least a portion of the rod in a rearward direction from the push-out position to the return position; and a bias element that biases the plunger to the return position by applying a force in the rearward direction to the plunger that drives the plunger to the return position; wherein the pre-use position of the rod, the return position of the plunger and the respective lengths of the rod and the plunger are such that a first movement of the plunger from the return position to the push-out position will result in only partial movement of the rod from the pre-use position to the fully extended position.
