  • Patent number: 8523941
    Abstract: An intraocular lens insertion instrument capable of smoothly pushing out a preset lens is provided. An intraocular lens insertion instrument comprises: a main body including a lens setting section on which a lens is set, a transition section that deforms the lens, and a nozzle piece that releases the lens; and a lens push-out mechanism that pushes out the lens set on the lens setting section. The instrument further includes a releasing means for releasing the lens pushed by the lens push-out mechanism from the lens setting section. The releasing means has a posture holding mount that holds the lens with a forward tilt relative to an axial line of lens movement. The posture holding mount has a passage through which the lens push-out mechanism passes.

  • Patent number: 8523877
    Abstract: An intraocular lens inserting instrument capable of folding a lens and pressing it by a plunger to discharge it into an eye and alternatively capable of taking out the folded lens by tweezers. The intraocular lens inserting instrument for inserting a foldable intraocular lens into an eye has a tubular body for allowing the intraocular lens to pass through it and introducing it into the eye, and a plunger for pressing the intraocular lens to discharge it into the eye, wherein the intraocular lens is folded by a folding member provided at a lens placing section. The lens placing section has an open/close lid so that the folded intraocular lens is accessible to be held by the tweezers.
