Claim Text:
1. An intraocular lens delivery system, comprising: a) a cartridge comprising a slot; b) a tubular handpiece having an interior wall; c) a plunger having an attached distally extending plunger rod, the plunger being sized and shaped to reciprocate within the tubular handpiece; and d) a sliding block having a groove, the groove sized and shaped to fit over the plunger rod; wherein forward movement of the sliding block within the slot of the cartridge also causes movement of the plunger rod and plunger, wherein the sliding block is frictionally engaged with the plunger rod so that movement of the sliding block causes movement of the plunger rod; wherein the sliding block is configured to be pushed forward until a button on the sliding block reaches a distal end of the slot configured to limit travel of the sliding block; wherein further forward movement of the plunger rod after the sliding block reaches the distal end of the slot is accomplished by pressing on an end cap of the plunger; wherein during the further movement of the plunger rod, the sliding block acts as a stiffener to reduce bending and buckling of the plunger rod.
