Abstract

An ophthalmic device is provided for a patient that has a basic prescription for distant vision, the ophthalmic device including a primary optic and a supplemental optic. The primary optic is configured for placement in the eye and has a base optical power configured to substantially provide the basic prescription. The supplemental optic has an optical power that is less than the optical power of the primary optic and is configured to provide, in combination with the primary optic, a combined optical power that provides the basic prescription of the patient. In addition, at least one surface of the primary optic is configured to deform in response to an ocular force so as to modify the combined optical power by at least 1 Diopter. The ophthalmic device may further include a movement assembly operably coupled to the primary optic that is structured to cooperate with the eye to effect accommodating deformation of the primary optic in response to an ocular force produced by the eye. The movement assembly may also be configured to provide accommodating axial movement of the primary optic.

Claims

9. The ophthalmic device of claim 1, wherein the supplemental optic is a diffractive optic.

10. The ophthalmic device of claim 1, wherein the primary optic is configured to be disposed within a capsular bag of the eye.

11. The ophthalmic device of claim 1, wherein the supplemental optic is configured to be disposed within an anterior chamber of the eye.

12. The ophthalmic device of claim 1, wherein the supplemental optic is configured to be implanted separately from the primary optic.

13. The ophthalmic device of claim 1, wherein the supplemental optic is a corneal implant configured to be disposed within a cornea of the eye.

14. The ophthalmic device of claim 1, wherein the supplemental optic is a surface profile disposed on or within the cornea and is formed by a laser.
