An intraocular lens injector comprising: an injector body comprising: a main body; a nozzle coupled to a distal end of the main body; a bore extending through the nozzle; and a pinion pivotably coupled to the injector body and comprising a plurality of teeth; and a plunger at least partially disposed in the injector body and moveable therein, the plunger comprising: a plunger body; a rack disposed on the plunger body and comprising a plurality of teeth, the pinion and the rack interoperable to advance the plunger in a first axial direction towards a distal end of the nozzle in response to a rotation of the pinion; a plunger rod coupled to a distal end of the plunger body; and a plunger tip formed at a distal end of the plunger rod, the plunger tip adapted to contact an IOL. the plunger movable a first distance within the injector body in response to an axial force applied to the plunger free from engagement between the rack and the pinion, and, the plunger moveable in response to rotation of the pinion over a second distance within the injector body when the pinion is rotatably coupled with the rack and the plunger; characterised in that the main body further comprises a slot, wherein the plunger further comprises a flange extending through the slot, and wherein the flange is displaceable in the slot to move the plunger from a first position to a second position; wherein movement of the flange from the first position to the second position is operable to displace an IOL from a storage position in the nozzle to a dwell position in the nozzle; and the intraocular lens injector further comprising a barrier adapted to engage the flange to define the second position; and wherein the barrier is a removable barrier insertable into the slot. an injector body comprising: a main body; a nozzle coupled to a distal end of the main body; a main body; a nozzle coupled to a distal end of the main body; a bore extending through the nozzle; and a pinion pivotably coupled to the injector body and comprising a plurality of teeth; and a plunger at least partially disposed in the injector body and moveable therein, the plunger comprising: a plunger body; a rack disposed on the plunger body and comprising a plurality of teeth, the pinion and the rack interoperable to advance the plunger in a first axial direction towards a distal end of the nozzle in response to a rotation of the pinion; a plunger rod coupled to a distal end of the plunger body; and a plunger tip formed at a distal end of the plunger rod, the plunger tip adapted to contact an IOL. a plunger body; a rack disposed on the plunger body and comprising a plurality of teeth, the pinion and the rack interoperable to advance the plunger in a first axial direction towards a distal end of the nozzle in response to a rotation of the pinion; a plunger rod coupled to a distal end of the plunger body; and a plunger tip formed at a distal end of the plunger rod, the plunger tip adapted to contact an IOL. the plunger movable a first distance within the injector body in response to an axial force applied to the plunger free from engagement between the rack and the pinion, and, the plunger moveable in response to rotation of the pinion over a second distance within the injector body when the pinion is rotatably coupled with the rack and the plunger; characterised in that the main body further comprises a slot, wherein the plunger further comprises a flange extending through the slot, and wherein the flange is displaceable in the slot to move the plunger from a first position to a second position; wherein movement of the flange from the first position to the second position is operable to displace an IOL from a storage position in the nozzle to a dwell position in the nozzle; and the intraocular lens injector further comprising a barrier adapted to engage the flange to define the second position; and wherein the barrier is a removable barrier insertable into the slot.
