Abstract
An intraocular lens (10) is configured so that it can be incorporated into the capsule of an eye and its refractive power can be modified by the application of electrical voltages.
Claims19
Intraocular lens (10) having electrodes (22a, 22b, 22c, 22d, 22e, 22f) for applying electrical voltages to the lens in order to modify the mechanical surface tension of the lens and its shape.
Intraocular lens according to one of the preceding claims, characterised in that the electrical voltage causes a sphero-symmetrical deformation of the lens.
(canceled)
An intraocular lens assembly with a refractive power that is altered by application of an electrical energy, the intraocular lens assembly comprising:
- a liquid lens body having an unaccommodated state in the absence of electrical energy with a first refractive power;
- and
- a plurality of electrodes couplable to said lens body, said electrodes configured to deliver energy 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 electrical energy, said accommodated shape having a second refractive power different from said first refractive power.
A method of implanting an adjustable intraocular lens into a human eye, comprising:
- inserting a liquid lens into an optical beam path of the human eye;
- implanting one or more electrodes adjacent to the liquid lens;
- and
- applying a voltage to the one or more electrodes to adjust the curvature of the liquid lens.
