Provided is an intraocular lens insertion apparatus capable of stably inserting an intraocular lens while reducing stress imposed on ocular tissues. The intraocular lens insertion apparatus includes a substantially tubular insertion member configured to be inserted into an eye, an opening part provided at a tip end of the insertion member to eject an intraocular lens into the eye, and an intraocular lens push member which pushes the intraocular lens to move the intraocular lens through the insertion member and ejects the intraocular lens from the opening part into the eye, an opening direction of the opening part is tilted with respect to a direction in which the insertion member extends, a recess having a predetermined depth and extending in the extending direction is provided at an outer peripheral surface of the insertion member on an insertion member rear end side of the opening part, and the recess enlarges/contracts the opening part by elastic deformation when the insertion member is inserted into the eye and when the intraocular lens moves through the insertion member.
