ABSTRACT:
An intraocular lens (IOL) insertion system for implanting IOLs into the eye. The insertion system includes an insertion cartridge that receives the IOL and cooperates with a handpiece. The cartridge includes a longitudinal lumen from a loading chamber to an open distal mouth that gradually narrows in dimension so as to fold the IOL into a tube for insertion through an incision in the eye. A distal tip member of a plunger rod in the handpiece enters the loading chamber of the cartridge and urges the IOL therethrough. The distal tip member has a portion that enters the folded IOL and is trapped therein for maximum control of IOL advancement. A soft tip, such as silicone, may cover a longitudinally extending portion of the distal tip to effect the IOL trapping. The distal tip member further has a portion that engages and pushes the IOL optic. The pusher portion not only ensures positive advancement of the IOL, but also limits the extent to which the distal tip member becomes trapped inside the folded IOL, thus preventing potential damage thereto.
