• a push member for pushing the IOL toward the front end of the injection part, the push member being movable back and forth along an axis extending from the front end of the injection part to a rear end of the intraocular lens injection instrument;
• a restriction member attached to the cylinder body part to restrict movement of the IOL which is placed outside the axis;
• and
• a release member for releasing restriction of the movement of the IOL restricted by the restriction member and pushing the IOL onto the axis,
• wherein the release member includes a contact portion to be brought into contact with the IOL when the restriction by the restriction member is released, the contact portion having a setting surface to be brought into contact with the IOL placed on the axis.
