  • Patent number: 8968328
    Abstract: An intraocular lens insertion instrument capable of smoothly pushing out a preset lens is provided. An intraocular lens insertion instrument (1) comprises: a main body (3) including a lens setting section (8) on which a lens (2) is set, a transition section (22) that deforms the lens (2), and a nozzle piece (21) that releases the lens (2); and a lens push-out mechanism (4) that pushes out the lens (2) set on the lens setting section (8). The instrument (1) further includes a releasing means (11) for releasing the lens (2) pushed by the lens push-out mechanism (4) from the lens setting section (8). The releasing means (11) has a posture holding mount (12) that holds the lens (2) with a forward tilt relative to an axial line (A) of lens movement. The posture holding mount (12) has a passage (15) through which the lens push-out mechanism (4) passes.
