Abstract: An intraocular lens (IOL) includes a lens body having an anterior surface and a posterior surface disposed about an optical axis, and a progressive phase step structure formed on a refractive surface profile of at least one of the anterior surface or the posterior surface, the at least one of the anterior surface or the posterior surface having an outer zone, an inner zone, and a transition zone continuously connecting the outer zone and the inner zone. The refractive surface profile in the outer zone provides a base power, and the refractive surface profile in the inner zone provides an add power. The progressive phase step structure includes a first annular ridge structure within the inner zone, and a second annular ridge structure extending radially from the transition zone to the outer zone.

Abstract: The present disclosure provides an ophthalmic lens (such as an IOL) that is designed to enhance depth of focus for intermediate vision performance, while maintaining distance vision. The lens may include an optic having an anterior surface and a posterior surface disposed about an optical axis. One of the surfaces (e.g., the anterior surface) may have a surface profile involving a superposition of at least three structures or profiles, including a base structure, a phase shift structure having an inner region, an outer region and a transition region, and a zonal structure having an inner power zone and an outer transition zone.

Abstract: The present disclosure provides an ophthalmic lens that is disposed to balance coma aberrations if the lens, when inserted in a patient's eye, is decentered or tilted with respect to an optical axis of the patient's eye, and maintain a substantially diffraction-limited image quality if the lens, when inserted in the patient's eye, is centered with respect to the optical axis of the patient's eye. The lens may include an optic having an anterior surface and an opposing posterior surface disposed about an optical axis of the lens. One of the surfaces (e.g., the anterior surface) may have a semi-aspheric surface profile, which includes an inner region having a substantially spherical surface profile and extending radially from the optical axis of the lens to a first boundary, and an outer region having an aspherical surface profile and extending radially at least beyond the first boundary to a second boundary.
