An injector having a hollow cylindrical body having a first, discharge end and a second, plunger end, and a plunger which is axially slidable within the body. A first end of the plunger is adapted to contact either an IOL or a cartridge containing an IOL and to force the IOL out of the injector or cartridge into the eye. A second end of the plunger has a knob or stop proximate the pushing end, used to grip the plunger and move it into the housing. Located on the housing proximate the second end is a micrometer barrel rotatably and threadedly mounted to the injector housing. When the plunger is fully pushed into the injector housing, the knob contacts the micrometer collar thus halting the inward movement of the plunger. The micrometer collar is rotatably adjustable with respect to the housing thereby altering the position at which the plunger knob contacts the micrometer dial and, thereby, adjusting the distance to which the the plunger extends toward or past the discharge end of the injector.
