OG exemplary drawing
 
1. An intraocular lens (IOL), comprising:
a first surface and a second surface disposed about an optical axis;
a refractive profile imposed on one of the first surface or the second surface; and
a diffractive profile imposed on one of the first surface or the second surface;
wherein the refractive profile comprises:
a continuous high order aspheric surface profile that results in a continuous optical power progression;
a first region of the lens approximating a first optical regime; and
a second region of the lens approximating a second optical regime;
wherein the first and second regions are radially symmetric and concentric about an optical axis of the lens, the second region being disposed around the first region;
wherein the first and second regions are merged by a continuous aspheric lens function so that the first region blends continuously into the second region;
wherein the diffractive profile comprises at least one set of diffractive zones that partially corrects for ocular chromatic aberration; and
wherein the combination of the refractive profile and the diffractive profile provides an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.
