    • An intraocular lens for providing enhanced vision includes an optic having a clear aperture having an outer diameter. The optic has opposing first and second surfaces disposed about an optical axis, the first surface including a cross- sectional profile. The optic further includes central and outer zones that fill the entire clear aperture of the optic. The central zone is disposed about the optical axis having an outer diameter, the profile in the vicinity of the central zone having a constant radius of curvature or a radius of curvature that increases with increasing radius from the optical axis. The outer zone is disposed about the central zone, the profile in the outer zone having a base curvature with a base radius of curvature and a center of curvature, the profile in the outer zone characterized in that, as the distance from the optical axis increases, the distance from the center of curvature of the base curvature also increases.

    • An intraocular lens for providing enhanced vision includes an optic with a clear aperture over which light may be focused onto or near the retina of an eye. The optic includes an anterior surface and an opposing posterior surface, the surfaces disposed about an optical axis. The optic includes a central zone and an outer zone disposed about the central zone. The central zone comprises a plurality of optical powers that progressively vary between a first optical power at a center of the central zone and a second optical power at a periphery of the central zone, wherein the absolute value of the difference between the first optical power and the second optical power being between predetermined values. The outer zone comprises a third optical power and may also have a negative spherical aberration. The optic typically has a variation in optical power over the entire clear aperture that is less than a predetermined amount.
