Patent ID: 8460376

Claim:
An accommodating intraocular lens assembly with a refractive power that is altered by application of an electrical voltage, the intraocular lens assembly comprising: a liquid lens body sized and shaped for implantation within the eye, the liquid lens body having an unaccommodated state in the absence of electrical voltage with a first refractive power, the liquid lens body enclosed by an insulating liquid and configured to be fitted into the capsule of an eye; and a plurality of electrodes sized and shaped for implantation within the eye, the plurality of electrodes couplable to said lens body, said electrodes configured to deliver an electrical voltage to said liquid lens body, said liquid lens body having an accommodated state when one or more of said plurality of electrodes is energized with the electrical voltage for changing the surface tension of a liquid or liquid-like material in the liquid lens, said accommodated shape having a second refractive power different from said first refractive power wherein the changed surface tension produces a deformation of the intraocular lens to compensate for an astigmatism or to compensate for higher-order aberrations; and a microchip sized and shaped for implantation within the eye, the microchip electrically coupled to said plurality of electrodes, the microchip configured to derive a triboelectrical voltage from a force generated by natural accommodation of the eye, amplify said derived voltage, and apply said amplified voltage to said plurality of electrodes to deform said liquid lens body between said unaccommodated state and said accommodated state such that the intraocular lens assembly provides accommodation as a function of natural movement of a ciliary muscle of the eye associated with the natural accommodation of the eye, wherein the surface tension of the liquid or liquid-like material in the liquid lens body is changed by electro-wetting.
