Abstract:
An insertion apparatus for inserting an intraocular lens having an optic and at least one fixation member in a patient's eye, comprising:an insertion cartridge having a proximal loading chamber sized to receive the intraocular lens in an unfolded configuration, and a distal injection tube having an open distal mouth sized to fit through an incision in the eye, the insertion cartridge further including a lumen connecting the loading chamber and the open distal mouth that reduces in size therebetween to cause the intraocular lens to fold into a smaller size than its unfolded configuration when pushed through the lumen; and a push rod having a distal tip for pushing the intraocular lens through the insertion cartridge from the loading chamber through the connecting lumen and out the open distal mouth, the push rod defining a longitudinal axis and wherein the distal tip in transverse cross-section has a longitudinally extending runner on its lower surface and on one side thereof that creates an adjacent relief channel on the other side.
