Provided is an intraocular lens insertion instrument that can further stabilize the behavior of an intraocular lens. This intraocular lens insertion instrument has: a substantially cylindrical instrument main body having, at the distal end thereof, an insertion tube part for inserting into an eye, in a folded state, an intraocular lens having a lens main body and a support part； a storage unit for storing the intraocular lens； and an extrusion member for pushing and moving the intraocular lens within the insertion tube. The extrusion member has a distal end portion having a first protrusion section protruding in either the left or right direction and a second protrusion section protruding in the other (left or right) direction. When the intraocular lens is moved within the insertion tube part by the extrusion member, the first protrusion section comes into contact with a proximal portion of the support part from the front side in the optical axis direction of the intraocular lens, thereby regulating the forward movement of the proximal portion in the optical axis direction. The second protrusion section comes into contact with a distal portion of the support part from the front side in the optical axis direction, thereby regulating the forward movement of the distal portion in the optical axis direction.La présente invention concerne un instrument d'insertion de lentille intraoculaire qui peut en outre stabiliser le comportement d'une lentille intraoculaire. Cet instrument d'insertion de lentille intraoculaire présente : un corps principal d'instrument sensiblement cylindrique ayant, à son extrémité distale, une partie tube d'insertion pour l'insertion dans un œil, sous un état replié, une lentille intraoculaire ayant un corps principal de lentille et une partie support ； une unité de stockage pour stocker la lentille intraoculaire ； et un élément d'extrusion pour pousser et déplacer la lentille intraoculaire à l'intérieur du tube d'insertion.
