Abstract: The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) for implantation in the capsular bag of a patient's eye. The IOL 10 includes a fluid optic body (20) having a cavity (28) for containing an optical fluid, the cavity at least partially defined by a sidewall (26) extending around the cavity and defining a diameter of the cavity and a deformable optical membrane (22) intersecting the sidewall around a circumference of the sidewall and spanning the diameter of the cavity. The IOL further includes a second optic body (30) spaced a distance apart from the fluid optic body and a plurality of struts (40) extending from the sidewall and coupling the fluid optic body to the second optic body. The struts are configured such that axial compression of the capsular bag causes the struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane.

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: 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 method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, an optic axis and at least one diffractive grating pattern. The diffractive grating pattern(s) are disposed on at least one of the anterior surface and the posterior surface. The diffractive grating pattern(s) includes zones corresponding to distance ranges from the optic axis. Each of the zones has a plurality of echelettes having a radius of curvature corresponding to a focal length. The radius of curvature for each of at least a portion of the zones is different from the radius of curvature for another of the zones.
