Abstract

A flexible intraocular lens including a reinforcing layer disposed on a sidewall of the intraocular lens is described. An example flexible intraocular lens includes a lens body and a reinforcing layer disposed thereon.

First claim

What is claimed is:

1. An intraocular lens, comprising:
a lens body having at least one inner surface, wherein the lens body is formed from a flexible material amenable to implantation into an eye;
a reinforcing layer carried by the at least one inner surface, wherein a material that forms the reinforcing layer has a higher elastic modulus than the flexible material;
a conductor carried by at least a portion of the reinforcing layer, wherein the conductor is electrically coupled to adjust electrowetting behavior of the intraocular lens; and
a dielectric layer disposed over the conductor.

2. The intraocular lens of claim 1 , wherein the conductor covers less than all of the reinforcing layer.

3. The intraocular lens of claim 1 , wherein the lens body has an anterior side and a posterior side and recesses formed in the anterior and posterior sides, wherein the at least one inner surface defines an aperture through the lens body, and wherein the at least one inner surface is at an oblique angle to the anterior and posterior sides of the lens body.

4. The intraocular lens of claim 3 , further comprising a first optical window and a second optical window disposed in the recesses formed in the anterior and posterior sides of the lens body, respectively, and covering the aperture.

5. The intraocular lens of claim 4 , further comprising two immiscible liquids disposed in the aperture of the lens body, wherein a voltage applied to the conductor alters a wetting characteristic of the dielectric layer to cause an interface between the two immiscible liquids to change an optical power of the intraocular lens.

6. The intraocular lens of claim 1 , wherein the reinforcing layer comprises a polymeric material having a higher elastic modulus than the flexible material.

7. The intraocular lens of claim 1 , wherein the reinforcing layer comprises fibers.

8. The intraocular lens of claim 7 , wherein the fibers are embedded in a polymeric matrix.

9. The intraocular lens of claim 7 , wherein the reinforcing layer is embedded in a portion of the flexible material proximate to the at least one inner surface.

10. The intraocular lens of claim 7 , wherein the conductor is directly disposed on at least a portion of the fibers.

11. The intraocular lens of claim 7 , wherein the fibers have an average smallest dimension of between about 1 nm and about 400 nm.

12. The intraocular lens of claim 1 , wherein the reinforcing layer comprises particles embedded in a polymer matrix.

13. The intraocular lens of claim 1 , wherein the conductor comprises a self-healing material.

14. The intraocular lens of claim 1 , wherein the reinforcing layer is a first reinforcing layer, the intraocular lens further comprising a second reinforcing layer carried by the at least one inner surface and a contact pad and an interconnect carried by the second reinforcing layer, wherein a material that forms the second reinforcing layer has a higher elastic modulus than the flexible material.

15. The intraocular lens of claim 1 , wherein the lens body is flexibly capable of being rolled for insertion into an eye, and wherein the conductor does not crack or separate from the reinforcing layer when the intraocular lens is rolled.
