Abstract
In one aspect, the present invention provide an ophthalmic lens (e.g., an IOL) that includes an optic having an anterior optical surface and a posterior optical surface, where the optic provides an optical power in a range of about 16 D to about 25 D as measured in a medium having an index of refraction substantially similar to that of the eye's aqueous humor (e.g., about 1.336). At least one of the optical surfaces is characterized by an aspherical base profile such that the optic exhibits a negative spherical aberration in a range of about −0.202 microns to about −0.190 microns across the power range.
