1. An intraocular lens configured to improve vision for a patient'"'"'s eye, the intraocular lens comprising:

  • an optic comprising a first surface and a second surface opposite the first surface, the first surface and the second surface intersected by an optical axis, the optic being symmetric about the optical axis, wherein the first and the second surface of the optic are aspheric, the first surface having a first radius of curvature and a first conic constant and the second surface having a second radius of curvature and a second conic constant,wherein the first surface of the optic is configured to face the cornea and the second surface of the optic is configured to face the retina when the optic is implanted in the patient'"'"'s eye,wherein the first radius of curvature is less than the second radius of curvature,wherein the first conic constant is greater than the second conic constant, andwherein the optic is configured to improve image quality of an image produced by light incident on the patient'"'"'s eye at an oblique angle with respect to the optical axis and focused at a peripheral location disposed at a distance from the fovea and at an eccentricity between about 1 degree and about 25 degrees with respect to the optical axis at the fovea.
