An intraocular lens insertion apparatus includes a distal end member which is inserted through an incision in an eyeball of a patient, an opening member provided for the distal end member through which an intraocular lens is ejected, and an indicator provided for the distal end member. The indicator is used for indicating that an entire part of the opening member is inside a cornea of the eyeball or inside a sclerocornea of the eyeball with respect to an external flap of the incision.
