The present invention relates to an intraocular lens inserting instrument with which it is possible to stabilize the behavior of an intraocular lens during ejection thereof. This intraocular lens inserting instrument includes a substantially tubular instrument body having at its distal end an insertion tube portion (100) which inserts an intraocular lens into an eye, and a plunger which moves the intraocular lens to the distal end of the insertion tube portion (100), wherein: the insertion tube portion (100) has an opening portion (100a) for ejecting the intraocular lens; the open end surface of the opening portion (100a) is an inclined surface which is inclined relative to a surface orthogonal to the central axis (O) of the insertion tube portion; a frictional force imparting portion is provided in at least part of a second region (100g) of the inner wall surface of the insertion tube portion (100); the second region (100g) faces, across the central axis (O), a first region (100h) which extends a prescribed distance toward the rear end of the insertion tube portion (100) from a base end (100f) positioned on the side of the open end surface toward the rear end of the insertion tube portion; and the frictional force imparting portion causes a frictional force that is larger than a frictional force that is caused to act on the intraocular lens by means of the first region (100h) to act on the intraocular lens. |
