Abstract: An intraocular lens inserter can include a drive device with controllable advance motion. The drive device may include an actuator device and an energy device. The actuator device may include a piston rod that uses the advance motion to push an intraocular lens from a cartridge for insertion into an eye of an animal. The energy device may act upon the actuator device to generate the advance motion. The actuator device may include a dampening medium to control the advance motion, such as by controllably dampening the advance motion.

Abstract: Intraocular lens inserters and methods of use are disclosed. An example intraocular lens inserter may include an interior assembly having a movable member disposed therein. The movable member is movable in response to a pressure of a compressed gas. In response to the pressure of the compressed gas, the moveable member pressurizes a substantially incompressible fluid. The pressurized substantially incompressible fluid is used to advance a plunger. The plunger advances an intraocular lens through a lumen for insertion into an eye.
