Abstract

An intraocular lens (IOL) injector is configured for single hand operation and employs a compressed gas to provide a motive force to present an IOL to a surgical site. The IOL injector includes a mechanical brake coupled to a plunger to preclude translation of an IOL absent operator input. The mechanical brake provides for selectively varying the speed and translation of the plunger, and hence IOL during presentation of the IOL to a patient. The IOL injector can also include at least a first stop, which halts movement of the plunger at a predetermined position. The at least first stop is then moved to a passing position, thereby allowing further operator controlled translation of the plunger to present the IOL to the surgical site.
