Abstract

An anterior chamber phakic lens made from a foldable, highly biocompatible material that has a very low haptic compression force and low axial displacement, yet is stable in the anterior chamber.

Claims

1. An intraocular lens, comprising:

a) an optic having a diameter; and

b) at least one pair of footplates, the footplates being separated by a haptic and attached to the optic by a stem,

wherein the intraocular lens exhibits a force response of approximately less than 0.5 mN when the intraocular lens is compressed 1 mm.

2. The lens of claim 1 wherein the footplates are separated by the haptic by less than 1.5 times the diameter of the optic.

3. The lens of claim 1 wherein the footplates are separated by the haptic by approximately 1.3 times the diameter of the optic.

4. The lens of claim 1 wherein the lens is capable of being rolled or folded so as to fit through a 3.5 mm or less surgical incision.

5. The lens of claim 1 wherein an axial vaulting of the lens is less than 1.5 mm when the lens is compressed 1 mm.

6. The lens of claim 5 wherein the axial vaulting of the lens is less than 1.0 mm when the lens is compressed 1 mm.

7. The lens of claim 1 wherein the lens is made in a single piece entirely from a soft acrylic.

8. The lens of claim 1 wherein the lens is made in a single piece entirely from silicone.

9. The lens of claim 1 wherein the lens is made in a single piece entirely from a hydrogel.

10. An intraocular lens, comprising:

a) an optic having a diameter; and

b) a pair of footplates, each of the footplates being separated by a haptic and attached to the optic by a ramp, the optic, footplates and ramps being made in a single piece entirely from a soft acrylic,

wherein the intraocular lens exhibits a force response of approximately less than 0.5 mN when the intraocular lens is compressed 1 mm.

11. The lens of claim 10 wherein the footplates are separated by the haptic by less than 1.5 times the diameter of the optic.

12. The lens of claim 10 wherein the footplates are separated by the haptic by approximately 1.3 times the diameter of the optic.

13. The lens of claim 10 wherein the lens is capable of being rolled or folded so as to fit through a 3.5 mm or less surgical incision.

14. The lens of claim 10 wherein an axial vaulting of the lens is less than 1.5 mm when the lens is compressed 1 mm.

15. The lens of claim 14 wherein the axial vaulting of the lens is less than 1.0 mm when the lens is compressed 1 mm.
