Abstract

An intraocular lens insertion instrument includes: a tubular main body portion where an intraocular lens is placed; a rod-like pushing member inserted into the main body portion and configured to press the intraocular lens from a back toward a front of the main body portion in an axial direction, thereby push the intraocular lens in a folded state from a distal end of the main body portion to the outside, and then insert the intraocular lens into an eye; and a cylindrical insertion portion placed in the distal end of the main body portion to be inserted into the eye, in which the insertion portion includes a stress concentrated area where stress to be generated upon the folded intraocular lens passing through the insertion portion is concentrated, and the insertion portion includes a thick-walled structure in at least a part thereof, in which a thickness of the stress concentrated area of the insertion portion is set to be relatively greater than a thickness of an area of the insertion portion outside the stress concentrated area as the insertion portion is viewed in a direction of a central axis thereof.
