SYSTEM, OPHTHALMIC LENS, AND METHOD FOR EXTENDING DEPTH OF FOCUS
First Claim
Patent Images
1. An ophthalmic lens for an eye, the eye having an in-focus visual acuity and a depth of focus, the ophthalmic lens comprising:
- an optic having a central axis and a clear aperture disposed about the central axis, the optic comprising a first surface and an opposing second surface, the first and second surfaces together configured to introduce at least some asymmetric aberration to the eye to extend the depth of focus while maintaining the in-focus visual acuity.

Abstract
System, ophthalmic lens, and method for extending depth of focus includes an optic having a clear aperture disposed about a central axis. The optic includes a first surface and an opposing second surface. The first and second surfaces are configured to introduce an asymmetric aberration to the eye while maintaining the in-focus visual acuity.

16. A lens system for an eye, the eye having an in-focus visual acuity and a depth of focus, the lens system comprising:
-
a first lens having a first optical axis; and a second lens adjacent the first lens, the second lens having a second optical axis being non-aligned with the first optical axis, the first lens and second lens together configured to introduce at least some asymmetric aberration to the eye to extend the depth of focus while maintaining the in-focus visual acuity.

17. A method for modifying a depth of focus of an eye, the method comprising the steps of:
-
measuring a wavefront aberration of the eye; determining an in-focus visual acuity of the eye; and determining an asymmetric aberration to be induced in the wavefront aberration of the eye, the depth of focus being extended by the asymmetric aberration when induced in the wavefront aberration and while maintaining the in-focus visual acuity. - View Dependent Claims (18, 19, 20, 21, 22)
