Abstract:
1. An insertion system for inserting an intraocular lens having an optic and at least one fixation member into a patient's eye, the system being of the type that has a handpiece in which is held an insertion cartridge having a proximal loading chamber sized to receive the intraocular lens in a folded configuration, the loading chamber having an open proximal end, the system comprising: a plunger rod arranged to travel through the handpiece such that a distal tip member of the plunger rod lines up with the open proximal end of the loading chamber and thus can be advanced there through and push the intraocular lens through the loading chamber, the plunger rod defining a longitudinal axis and the distal tip member having a longitudinally extending portion that is sized to project and become trapped within the folded intraocular lens and a pusher surface locate proximal to and sized larger than the longitudinally extending portion that contacts and pushes the folded intraocular lens optic, wherein the pusher surface of the plunger rod distal tip member is offset from the longitudinal axis, the plunger rod distal tip member being made of a first material; and a soft tip made of a second material softer than the first material covering the longitudinally extending portion and sized to project and become trapped within the folded intraocular lens.
