Abstract
Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a plunger and an injector body that includes an insertion depth guard and a nozzle extending therefrom. The insertion depth guard is disposed at a distal end of the injector body to limit a distance that the nozzle penetrates the eye. The intraocular lens injector may also include a biasing element configured to generate a counterforce to distal movement of the plunger through the injector rod. An example intraocular lens injector may include a biasing element to produce a counterforce that opposes advancement of the plunger through the injector body. The counterforce provides for a more continuous advancement of the plunger while reducing or substantially eliminating abrupt changes in the rate at which the plunger is advanced through the injector body.
