PROBLEM TO BE SOLVED: To provide an intraocular lens insertion device capable of appropriately inserting an intraocular lens into an eye. An intraocular lens insertion device includes a nozzle and an extrusion member 310. The nozzle has a passage area narrower toward the front and an insertion port at the front end. The extrusion member 310 pushes the intraocular lens forward by moving forward in the passage along the axis of the nozzle passage. The extrusion member 310 pushes the intraocular lens forward in the passage of the nozzle, so that the support portion of the intraocular lens is bent onto the optical portion, and the optical portion is folded into a roll shape to form the folded optical portion. Position the support inside. The intraocular lens insertion device includes a pressing portion 327. The pressing portion 327 presses the rear supporting portion toward the optical portion in a state where the rear supporting portion is bent onto the optical portion.
