Abstract

Claims (19)

1 . An ophthalmic lens configured to improve vision quality for a patient's eye at locations spaced away from the fovea, the patient's eye having an existing artificial intraocular lens (IOL) disposed therein, the ophthalmic lens comprising:

an optic with a first surface and a second surface opposite the first surface, the first surface and the second surface meeting at a circumference of the optic, wherein the optic together with a cornea and the existing artificial intraocular lens in the patient's eye is configured to improve image quality of an image produced by light incident on the patient's eye in an angular range between about 1 degree and about 50 degrees with respect to the optical axis of the patient's eye and focused at a peripheral retinal location disposed at a distance from the fovea;

a haptic comprising a first arm comprising a first end coupled with a first location of the circumference and a second arm comprising a first end coupled with a second location of the circumference, the first arm extending radially and anteriorly away from the first location, the second arm extending radially and anteriorly away from the second location; and

a posterior displacer projecting posteriorly from the circumference of the optic to a free end configured to couple with the existing artificial intraocular lens;

wherein each of the first and second arm comprises a second end configured to brace against an ocular structure anterior to the lens capsule of the patient's eye and when so braced to position the posterior displacer in contact with the existing artificial intraocular lens, whereby the existing artificial intraocular lens is shifted posteriorly in the eye to displace a principal plane of the existing artificial intraocular lens posteriorly in the eye by a distance d such that an axial position of an optic of the existing artificial intraocular lens is displaced farther from an iris of the patient's eye in comparison to an original axial position of the optic of the existing artificial intraocular lens.

2 . The ophthalmic lens of claim 1 , wherein the posterior displacer is configured to contact an arcuate member disposed about an anterior face of the existing lens.

3 . The ophthalmic lens of claim 2 , wherein the arcuate member comprises a first ring segment disposed between two ends and a second ring segment disposed between two ends, adjacent ends of the first and second ring segments each forming one or more gap to receive a haptic of the existing artificial intraocular lens.

4 . The ophthalmic lens of claim 2 , wherein the free end of the posterior displacer comprises a notch having a first portion configured to be disposed along a side portion of the arcuate member and a second portion configured to be disposed along an anterior surface of the arcuate member.

5 . The ophthalmic lens of claim 2 , wherein the free end of the posterior displacer comprises an anteriorly angled face configured to mate with a posteriorly angled face of the anterior side of the existing artificial intraocular lens.

6 . The ophthalmic lens of claim 1 , wherein the second surface of the optic of the ophthalmic lens is configured to be spaced away from the anterior face of the existing artificial intraocular lens at a central optical axis of the existing artificial intraocular lens when the posterior displacer is in contact with the existing artificial intraocular lens.

7 . The ophthalmic lens of claim 1 , wherein

the first arm having a first length disposed at a first angle with respect to a transverse axis of the optic perpendicular to the optical axis of the patient's eye and passing through the first location, the second arm having a second length disposed at a second angle with respect to the transverse axis of the optic perpendicular to the optical axis of the patient's eye and passing through the second location.

8 . The ophthalmic lens of claim 7 , wherein the first length is equal to the second length.

9 . The ophthalmic lens of claim 8 , wherein the distance d is less than or equal to the first length.

10 . The ophthalmic lens of claim 7 , wherein the first length is greater than or equal to about 3.5 mm and less than or equal to about 5.0 mm.

11 . The ophthalmic lens of claim 7 , wherein the second length is greater than or equal to about 3.5 mm and less than or equal to about 5.0 mm.

12 . The ophthalmic lens of claim 7 , wherein the first angle is equal to the second angle.

13 . The ophthalmic lens of claim 7 , wherein the first angle is greater than or equal to about 15 degrees and less than or equal to about 45 degrees.

14 . The ophthalmic lens of claim 7 , wherein the second angle is greater than or equal to about 15 degrees and less than or equal to about 45 degrees.
