Abstract
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.
Claims20
An intraocular lens inserter comprising:
- an intraocular lens support portion configured to support an intraocular lens for insertion into an eye of an animal;
- an energy storage portion configured to receive a device with stored energy;
- an actuator portion configured to receive mechanical energy from the energy storage portion and to convert the receive mechanical energy into translational movement of a lens supported in the intraocular lens support portion.
An intraocular lens inserter comprising:
- an intraocular lens support portion;
- an energy storage portion containing a compressible energy storage medium;
- an actuator portion communicating with the energy storage portion and comprising a substantially incompressible fluid, the actuator portion configured to apply mechanical forces from the energy storage portion to the incompressible fluid for discharging an intraocular lens supported by the intraocular lens support portion.
A method for discharging an intraocular lens from an intraocular lens cartridge, the method comprising:
- releasing stored energy from a compressible energy storage medium;
- conducting the released energy from the compressible energy storage medium with a substantially incompressible fluid to a plunger;
- moving the plunger with the substantially incompressible fluid to push an intraocular lens out of an intraocular lens cartridge.
