  • Patent number: 8961531
    Abstract: An intraocular lens (IOL) transfer case for transferring an IOL to an injection cartridge includes a lens holder for holding the IOL. The lens holder includes a bore. Folding members within the lens holder are configured to fold the IOL into a partially folded position when the IOL is slid through the bore across the folding members. The IOL transfer case also includes an interface configured to removably connect to an injection cartridge. The interface is positioned to deliver the IOL in the partially folded position within the injection cartridge when the interface is connected to the injection cartridge. The IOL transfer case also includes a plunger connected to the lens holder and configured to push the IOL in the partially folded position through the bore to deliver the IOL into the injection cartridge.

  • Patent number: 8894664
    Abstract: A cartridge for an IOL delivery system that has an injector tip geometry designed to reduce stresses at the incision wound edges generated during insertion of an IOL into an eye is disclosed. The injector tip geometry includes a tubular nozzle having a modified elliptical cross section. The injector tip geometry reduces stresses generated reduce the likelihood of tearing or overstretching the wound during cartridge tip insertion and residence time in the wound while the lens is being delivered into the eye.
