Abstract:
1. An intraocular lens, comprising: an optic having a clear aperture having an outer diameter, the optic comprising: an outer zone disposed about the central zone, the outer zone comprising an inner diameter and an outer diameter equal to the outer diameter of the clear aperture, the outer zone characterized by a third optical power at the inner diameter which is less than the first paraxial optical power and selected to provide distance vision when the intraocular lens is disposed within the eye, wherein the outer zone further comprises a negative spherical aberration, wherein the central zone and the outer zone are the only two zones in the optic and entirely fill the clear aperture of the optic, wherein the variation in optical power over the entire clear aperture is less than or equal to 2.0 diopters, and wherein the central and outer zones are configured such that more light for distant vision under low lighting conditions is focused by the outer zone onto the surface of the retina.
