The present invention pertains to accommodating intraocular lens (AIOL) assemblies including a haptics system for self-anchoring implantation in a human eye's annular ciliary sulcus for retaining an AIOL at a desired position along the human eye's visual axis, and an accommodation measurement implant (AMI) for determining accommodation and accommodation forces in an experimental set-up including an animal's eye.

This invention relates to ophthalmic lens for spectacle comprising a primary glass, a secondary glass, a main chamber and a membrane configured to separate the volume of the main chamber in a first chamber and a second chamber.

Accommodating intraocular lenses and methods of use. The accommodating intraocular lenses include peripheral regions that are adapted to be more responsive to certain types of forces than to other types of forces. For example, the accommodating intraocular lenses can include haptics that are stiffer in an anterior-to-posterior direction than in a radial direction.

An accommodating intraocular lens assembly can include a first lens, a first plurality of stanchions, a second lens, and a second plurality of stanchions. A central optic axis can extend through centers of the first and second lenses. The first plurality of stanchions can each extend a first distance between a first base end and a first distal end. The first lens can be connected with the first distal ends. The second plurality of stanchions can each extend a second distance between a second base end and a second distal end. The second lens can be connected with the second distal ends. Compression at the peripheries of the stanchions induces movement of the lenses apart from one other.

An intraocular lens includes an optic having first and second sides. The optic has a first main lens surface at the first side, a second main lens surface at the second side, the first main lens surface providing a first main lens surface optical power, the second main lens surface providing a second main lens surface optical power, the first and second main lens surfaces providing a main lens having a main lens optical power and main optical axis defining radial, tangential and axial directions. The optic has: a first additional optical active part at the first side, providing a positive relative optical power with respect to the first main lens surface optical power; and a second additional optical active part at the second side, partly overlapping the first additional optical active part, providing a relative optical power and/or optical aberration with respect to the second main lens surface.

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 2? phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by ?. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.

A method for manufacturing a diffractive multi-focal ophthalmic lens capable of generating at least three focal points in an optical axis direction using a diffractive structure comprising a plurality of zones in a concentric circle form. A composite profile is generated by overlapping at least two starting profiles comprising a plurality of zones in a concentric circle form, and an adjusted profile is generated in which at least one of phase and amplitude is adjusted by employing a zone of the composite profile as a subject in order to set an intensity distribution in the optical axis direction and determine optical characteristics, to manufacture the diffractive multi-focal ophthalmic lens for which the adjusted profile is provided in at least a portion of the diffractive structure.

A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.

Intraocular lenses with a base optical power and a customized add power. The add power is customized based on at least one of ocular biometry of an individual, position of the intraocular lens in the eye and a preferred reading distance.
