Abstract

Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a lens body having a lens material and a mask having a mask material. The lens body can be secured to the mask. The mask material can include a modulus of elasticity that is greater than or equal to a modulus of elasticity of the lens material.

Claims

1. An intraocular lens comprising:

a lens body comprising a lens material, the lens body being flexible enough to be injected through an injector system and to revert back to its pre-injection shape, the injector system comprising an injector tip with an inner diameter less than or equal to about 2.0 mm; and

a mask with an aperture for improving depth of focus, the mask being opaque and flexible enough to be injected through the injector system and to revert back to its pre-injection shape, the mask comprising an opacification agent and a mask material, the mask material being different from the lens material,

wherein a pre-injection optical power of the intraocular lens is within about 0.5 diopters of a post-injection optical power of the intraocular lens.

2. The intraocular lens of claim 1, wherein the pre-injection optical power of the intraocular lens is within about 0.3 diopters of the post-injection optical power of the intraocular lens.

3. The intraocular lens of claim 1, wherein the mask material has a modulus of elasticity that is within about 30 percent of a modulus of elasticity of the lens material.

4. The intraocular lens of claim 1, wherein the modulus of elasticity of the mask material is greater than or equal to the modulus of elasticity of the lens material.

5. The intraocular lens of claim 1, wherein the modulus of elasticity of the mask material is less than the modulus of elasticity of the lens material.

6. The intraocular lens of claim 1, wherein the mask material comprises silicone.

7. The intraocular lens of claim 1, wherein the mask material comprises acrylic.

8. The intraocular lens of claim 1, wherein the mask comprises a thickness of less than or equal to about 200 microns.

9. The intraocular lens of claim 1, wherein the lens body has an outer diameter between about 3 mm and about 6 mm, and wherein the lens body is capable of insertion through an incision having a chord length of less than or equal to about 3.0 mm.

10. The intraocular lens of claim 1, wherein the mask is embedded entirely between a posterior surface and an anterior surface of the lens body.

11. A method of implanting an intraocular lens in an eye, the method comprising:

forming an incision in the eye;

injecting the intraocular lens through the incision using an injector system comprising an injector tip with an inner diameter less than or equal to about 2.0 mm, the intraocular lens comprising;

a lens body comprising a lens material, the lens body being flexible enough to be injected through the injector system and to revert back to its pre-injection shape; and

a mask with an aperture for improving depth of focus, the mask being opaque and flexible enough to be injected through the injector system and to revert back to its pre-injection shape, the mask comprising an opacification agent and a mask material, the mask material being different from the lens material,

wherein a pre-injection optical power of the intraocular lens is within about 0.5 diopters of a post-injection optical power of the intraocular lens.

12. The method of claim 11, wherein the incision has a chord less of less than or equal to about 2.4 mm.

13. The method of claim 11, wherein the pre-injection optical power of the intraocular lens is within about 0.3 diopters of the post-injection optical power of the intraocular lens.

14. The method of claim 11, wherein the mask material has a modulus of elasticity that is within about 30 percent of a modulus of elasticity of the lens material.

15. The method of claim 11, wherein injecting the intraocular lens through the incision comprises introducing the intraocular lens to a temperature differential of at least about 10°

C.

16. The method of claim 11, wherein when the intraocular lens is within the injector system, the intraocular lens is rolled up.
