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.

First claim

What is claimed is:

1. An ophthalmic device, comprising: a primary optic having a base optical power and configured for placement in a capsular bag of an eye of a patient having an optical axis; and a supplemental optic configured to be placed in an anterior chamber of the eye; and at least one fixation member coupled to the supplemental optic and configured to contact an angle of the eye; wherein the supplemental optic is maintained in a substantially stationary position in the anterior chamber and configured to correct the optical power of the primary optic, and the primary optic is configured to move axially along the optical axis in response to an ocular force of the eye.

2. The ophthalmic device of claim 1 , wherein the supplemental optic has an optical power that is within the range of about −4 Diopters to about +4 Diopters.

3. The ophthalmic device of claim 1 , further comprising a fixation member operably coupled to the supplemental optic.

4. The ophthalmic device of claim 1 , wherein at least one surface of the primary optic is configured to deform in response to an ocular force so as to provide an add power of at least 3 Diopters.

5. The ophthalmic device of claim 1 , wherein the supplemental is configured to correct at least one of a monochromatic aberration and a chromatic aberration of the primary optic and/or the eye.

6. The ophthalmic device of claim 1 , wherein the monochromatic aberration is at least one of an astigmatic aberration, a spherical aberration, and a comatic aberration.
