摘要： An intraocular lens insertion apparatus includes a distal end member which is inserted through an incision in an eyeball of a patient, an opening member provided for the distal end member through which an intraocular lens is ejected, and an indicator provided for the distal end member. The indicator is used for indicating that an entire part of the opening member is inside a cornea of the eyeball or inside a sclerocornea of the eyeball with respect to an external flap of the incision.

摘要： Provided is a configuration in which when a positioning member is removed from an intraocular lens insertion tool, restrictions on the position and posture of an intraocular lens can be lifted smoothly without exerting influence on the intraocular lens and the insertion tool itself. The present invention is provided with: an approximately cylindrical nozzle body (10); a stage part which is provided in the nozzle body (10) and houses an intraocular lens; a plunger which presses the intraocular lens housed in the stage part by the forward end thereof to discharge the intraocular lens into an eyeball; and a positioning member (60) which restricts the initial position and posture of the intraocular lens by being mounted to the stage part from the outside. Rib sections (12g) are formed so as to extend in the front-back direction of the nozzle body (10) at the outer periphery of the stage part, and side wall parts (51, 51) and rotation prevention wall parts (59, 59) are formed in the positioning member (60) so as to sandwich the rib sections (12g, 12g) from both sides, thereby restricting the rotation of the positioning member (60) with respect to the stage part.
