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.

Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2π phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by π. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.

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: A multi-layer intraocular lens (IOL) includes a lens body, including an anterior diffractive optics layer, comprising a first biocompatible material, and a posterior diffractive optics layer, comprising a second biocompatible material that is different from the first biocompatible material. The anterior diffractive optics layer and the posterior diffractive optics layer are sealed in a peripheral non-optic portion of the lens body with a gap between the anterior diffractive optics layer and the posterior diffractive optics layer.
