PROBLEM TO BE SOLVED: To provide an intraocular lens injector which suppresses changes in an operation pressure during normal operation while the push-out operation of an intraocular lens is carried out and facilitates the determination of whether the push-out operation is normal or not. SOLUTION: The intraocular lens injector includes an interference part which is provided in a passage of a push-out rod and makes contact with the push-out rod to generate frictional force between the interference part and the push-out rod to apply a prescribed operation pressure to the push-out rod while the intraocular lens is pushed out by the push-out rod toward an insertion part for inserting the intraocular lens in an eye. The push-out rod is characterized in that a region in the axial direction of the push-out rod relative to the interference part in a range where a diameter of the intraocular lens is reduced by an internal shape of the insertion part with the frictional force generated by the contact between the insertion part and the intraocular lens increased is treated or formed to reduce the frictional force with the interference part or is configured to have a shape to prevent the contact between the push-out rod and the interference part in the region.
