Ophthalmic implants with extended depth of field and enhanced distance visual acuity

A lens configured for implantation into an eye of a human, said lens comprising:

• an optic comprising transparent material, said optic having an anterior surface and a posterior surface, said anterior surface being convex and said posterior surface being concave such that said optic is meniscus shaped, each of said convex anterior surface and said concave posterior surface having a surface vertex, said optic having an optical axis through said surface vertices,
• at least one haptic disposed with respect to the optic to affix the optic in the eye when implanted therein,
• wherein said anterior and posterior surfaces comprise aspheric surfaces and said anterior surface has an aspheric shape that comprises a conic or biconic offset by perturbations comprising an aspheric higher order function of radial distance from the optical axis, and wherein said anterior and posterior surfaces are shaped so as not to produce discrete spaced apart foci where light is focused along said optical axis.
