  • Intraocular lens injection system
    Patent number: 5976150
    Abstract: A hinged, relatively rigid substrate on which a foldable IOL is held by a thin, relatively non-elastic film of esterified hyaluronate. When the substrate is folded along the hinge, the film covering the IOL causes the IOL to also fold along the hinge. The folded lens can then be placed in a conventional IOL injector handpiece that has been modified to include a cutter or the like to separate the film-encased IOL from the substrate prior to injection into the eye.
