An intraocular lens inserter can include an energy storage portion, an actuator portion, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid, such as liquids or other noncompressible fluids. The actuator can be configured to provide an operator with control over the release of energy from the energy storage portion so as to move a plunger for the discharge of a lens from an intraocular lens cartridge.
