Abstract: An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface has a surface profile including a base curvature, a refractive region having the base curvature, and a diffractive region comprising a diffractive profile including a plurality of diffractive steps. At least a portion of the diffractive profile constitutes a combination of a base diffractive profile defining multiple foci for the ophthalmic lens and an achromatizing structure that reduces longitudinal chromatic aberrations.

Abstract: Certain embodiments provide an intraocular lens (IOL) including a lens body having an anterior lens element and a posterior lens element, and an optical fluid in a cavity formed between the anterior lens element and the posterior lens element. The anterior lens element and the posterior lens element each comprise a lens material having a first Abbe number, and the optical fluid has a second Abbe number that is less than the first Abbe number.

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: 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.

Abstract: In certain embodiments, an ophthalmic lens includes an optic having an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface includes a first zone extending from the optical axis to a first radial boundary and a second zone extending from the first radial boundary to the edge of the optic. The first zone includes an inner region and an outer region separated by a phase shift feature, the phase shift comprising a ridge extending outwardly from the inner region and the outer region.
