A foldable intraocular lens is stored in its normal unfolded configuration within a lens storage chamber in a lens insertion instrument (10) containing a ram (36) which is movable inwardly through the chamber to move the lens into and fold the lens to a compact folded configuration within a bore (30) extending through a tubular portion (24) of the instrument terminating in a slender tip (26) for insertion into a patient's eye through a corneal incision in the eye and through which the folded lens is ejected into the eye by a plunger (40) movable through the bore. <??>The plunger (4) is operated by an insertion actuator with a finger wheel (64). The insertion actuator comprises a pinion (66) rotable by the instrument user to cooperate with a rack teeth (72) on the plunger (40). <IMAGE>
