CLAIMS

1 . An ophthalmic lens, comprising

an optic comprising an anterior surface, a posterior surface, and an optic edge extending between the anterior surface and the posterior surface, the optic having an optical axis; and

a plurality of haptics extending from a periphery of the optic, each of the plurality of haptics comprising a gusset region, a distal region, and an elbow region connecting the gusset region to the distal region, wherein:

the gusset region of each of the plurality of haptics extends from the periphery of the optic and spans a portion of the periphery of the optic;

the gusset region of each of the plurality of haptics monotonically increases in thickness with increased distance from the periphery of the optic; and the distal region of each of the plurality of haptics monotonically decreases in thickness with increased distance from the elbow region.

2. The ophthalmic lens of Claim 1 , wherein the portion of the periphery of the optic spanned by the gusset region of each of the plurality of haptics is at least sixty degrees of the periphery of the optic.

3. The ophthalmic lens of Claim 1 , wherein the portion of the periphery of the optic spanned by the gusset region of each of the plurality of haptics is approximately seventy degrees of the periphery of the optic.

4. The ophthalmic lens of Claim 1 , wherein the elbow region of each of the plurality of haptics comprises a region of each haptic having a minimum haptic width.

5. The ophthalmic lens of Claim 1 , wherein each of the plurality of haptics comprising an anterior haptic surface and a posterior haptic surface, wherein, for at least a portion of each of the plurality of haptics, a width of the posterior haptic surface is greater than a width of the anterior haptic surface.

6. The ophthalmic lens of Claim 1 , wherein at least a portion of a surface of each of the plurality of haptics is textured.

7. The ophthalmic lens of Claim 1 , wherein:

the optic edge defines a surface having a single radius of curvature; and the surface does not have any tangents parallel to the optical axis.

8. The ophthalmic lens of Claim 1 , wherein the distal region of each of the plurality of haptics linearly decreases in thickness with increased distance from the optical axis.

9. The ophthalmic lens of Claim 1 , wherein the distal region of each of the plurality of haptics non-linearly decreases in thickness with increased distance from the elbow region.

10. The ophthalmic lens of Claim 1 , wherein the gusset region of each of the plurality of haptics linearly increases in thickness with increased distance from the periphery of the optic.

1 1 . The ophthalmic lens of Claim 1 , wherein the gusset region of each of the plurality of haptics non-linearly increases in thickness with increased distance from the periphery of the optic.

12. An ophthalmic lens, comprising

an optic comprising an anterior surface, a posterior surface, and an optic edge extending between the anterior surface and the posterior surface, the optic having an optical axis;

a plurality of haptics extending from a periphery of the optic, each of the plurality of haptics comprising a gusset region, a distal region, and an elbow region connecting the gusset region to the distal region, wherein:

the gusset region of each of the plurality of haptics extends from the periphery of the optic and spans approximately seventy degrees of the periphery of the optic;

the gusset region of each of the plurality of haptics monotonically increases in thickness with increased distance from the periphery of the optic;

the elbow region of each of the plurality of haptics comprises a region of each haptic having a minimum haptic width;

the distal region of each of the plurality of haptics monotonically decreases in thickness with increased distance from the elbow region; and

at least a portion of a surface of each of the plurality of haptics is textured.

13. The ophthalmic lens of Claim 12, wherein each of the plurality of haptics comprising an anterior haptic surface and a posterior haptic surface, wherein, for at least a portion of each of the plurality of haptics, a width of the posterior haptic surface is greater than a width of the anterior haptic surface.

14. The ophthalmic lens of Claim 1 2, wherein:

the optic edge defines a surface having a single radius of curvature; and the surface does not have any tangents parallel to the optical axis.

15. The ophthalmic lens of Claim 1 , wherein the distal region of each of the plurality of haptics linearly decreases in thickness with increased distance from the optical axis.

16. The ophthalmic lens of Claim 1 , wherein the distal region of each of the plurality of haptics non-linearly decreases in thickness with increased distance from the elbow region.

17. The ophthalmic lens of Claim 1 , wherein the gusset region of each of the plurality of haptics linearly increases in thickness with increased distance from the periphery of the optic.

18. The ophthalmic lens of Claim 1 , wherein the gusset region of each of the plurality of haptics non-linearly increases in thickness with increased distance from the periphery of the optic.
