Provided is a technology which, when inserting an intraocular lens into an eyeball, is capable of releasing the intraocular lens from a tip of an insertion device more smoothly while maintaining orientation of the intraocular lens. An intraocular lens insertion device comprises: a nozzle main body which has a nozzle part (15) which is inserted into an incision; a stage part which is capable of disposing an intraocular lens (2) inside the nozzle main body by setting the intraocular lens (2) thereon; and a plunger (60) which presses, with a tip thereof, the intraocular lens (2) that is pushed inside the nozzle main body and set on the stage part and releases the intraocular lens (2) into the eyeball from a tip part (10a) of the nozzle part (15). The tip part (10a) of the nozzle part (15) is obliquely cut so that the end face is positioned more to the front side from a rear side of an optical axis of the intraocular lens (2) toward a front side thereof and a tip (61d) of the plunger (60) is provided with a projection part (61e) which projects to the front side so that the face on the rear side of the optical axis of the intraocular lens (2) can be placed thereon. |
