  • Automated intraocular lens injector device
    Patent number: 9421092
    Abstract: An intraocular lens injector cartridge assembly contains a pre-loaded lens and an integral lens-contacting plunger rod. Configured for removably mating with an injector handpiece, the cartridge assembly is suitable for use with either manual or automated injector systems. The injector cartridge assembly includes a tubular body having a longitudinal bore extending between a distal end and a proximal end, an IOL disposed within said longitudinal bore, and a lens-contacting plunger rod retained within said bore, between the IOL and the proximal end of the tubular body. The lens-contacting plunger rod is configured for translation along the longitudinal bore upon engagement by an injector rod introduced by the injector handpiece into the proximal end of the tubular body, so that the IOL is folded and ejected from the distal end of the tubular body by the translation of the lens-contacting plunger rod.
