First claim

What is claimed is:

1. An implantable intraocular lens system comprising an optical zone and an electrical zone adjacent thereto, wherein:
the optical zone comprises:
a single continuous front curve lens comprising a front curve lens exterior surface and a front curve lens interior surface;
a single continuous back curve lens comprising a back curve lens interior surface and a back curve lens exterior surface, said back curve lens is secured to said front curve lens such that said front curve lens interior surface and said back curve lens interior surface form a cavity therebetween, said front curve lens and said back curve lens of size and shape to replace an intraocular lens in a human eye;
a volume of oil and a volume of saline solution contained within the cavity with a meniscus formed between said volume of oil and said volume of saline solution, wherein said meniscus comprises an optical characteristic; and
a conductive coating consisting of a first conductive material directly on at least a perimeter area of one or both of said front curve lens interior surface and said back curve lens interior surface; and

the electrical zone comprises a power source for applying an electrical charge to the conductive coating, wherein the application of the electrical charge causes a change of the optical characteristic of said meniscus.

2. The implantable intraocular lens system of claim 1 additionally comprising a microprocessor positioned in the electrical zone proximate to the front curve lens and the back curve lens, said microprocessor in electrical communication with the power source to control the application of the electrical charge to the conductive coating.

3. The implantable intraocular lens system of claim 1 additionally comprising an adhesive securing said front curve lens to the back curve lens, wherein at least one of said front curve lens exterior surface and said back curve lens exterior surface comprises an arcuate shape.

4. The implantable intraocular lens system of claim 3 wherein both of said front curve lens exterior surface and said back curve lens exterior surface comprise arcuate shapes.

5. The implantable intraocular lens system of claim 3 wherein the front curve lens exterior surface comprises an optical power other than 0 diopters.

6. The implantable intraocular lens system of claim 3 wherein the front curve lens interior surface comprises an optical power other than 0 diopters.

7. The implantable intraocular lens system of claim 3 wherein the back curve lens interior surface comprises an optical power other than 0 diopters.

8. The implantable intraocular lens system of claim 1 wherein the power source comprises a battery.

9. The implantable intraocular lens of claim 1 additionally comprising a wireless transmitter for communicating logic to and from a microprocessor.

10. The implantable intraocular lens system of claim 9 wherein the communicated logic modifies a focus of the optical characteristic formed by the meniscus.

11. The implantable intraocular lens system of claim 10 wherein the volume of oil is less than the volume of saline solution contained within the cavity.

12. The implantable intraocular lens system of claim 11 wherein the volume of oil is 66% or more of the volume of saline solution.

13. The implantable intraocular lens system of claim 12 wherein the electrical charge comprises a direct current.

14. The implantable intraocular lens system of claim 13 wherein the electrical charge is 20.0 volts.

15. The implantable intraocular lens system of claim 13 wherein the electrical charge is between 18.0 volts to 22.0 volts.

16. The implantable intraocular lens system of claim 13 wherein the electrical charge is 5.0 volts.

17. The implantable intraocular lens system of claim 13 wherein the electrical charge is between 3.5 volts to 7.5 volts.

18. The implantable intraocular lens system of claim 11 wherein the volume of oil is 90% or less of the volume of saline solution.

19. The implantable intraocular lens system of claim 18 wherein the conductive coating extends from an area internal to the cavity to an area external to the cavity.

20. The implantable intraocular lens system of claim 19 wherein the conductive coating which extends to the area external to the cavity forms an electrical terminal for providing the electrical charge to the conductive coating based upon a signal from the microprocessor.

21. The implantable intraocular lens system of claim 19 additionally comprising a channel through one or both of the front curve lens and the back curve lens and a second conductive material filling the channel.

22. The implantable intraocular lens system of claim 21 additionally comprising a terminal in electrical communication with the second conductive material filling the channel.

23. The implantable intraocular lens system of claim 22 wherein the application of the electrical charge to the terminal causes a change in an arcuate shape of the meniscus.

24. The implantable intraocular lens system of claim 19 additionally comprising an insulator coating along at least a second portion of the interior surface of the front curve lens, wherein the insulator coating comprises an electrical insulator.

25. The implantable intraocular lens system of claim 24 wherein the insulator coating comprises a boundary area to maintain separation between the conductive coating and the volume of saline solution contained in the cavity between the front curve lens and the back curve lens.

26. The implantable intraocular lens of claim 1 , wherein the conductive coating is directly on the perimeter area of both of said front curve lens interior surface and said back curve lens interior surface.

27. An implantable intraocular lens system comprising an optical zone and an electrical zone adjacent thereto, wherein:
