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.

An accommodating intraocular lens assembly can include a first lens, a first stanchion, a second lens, and a second stanchion. The first lens can have a first anterior side and a first posterior side. The first stanchion can have a first distal end connected to the first lens and a first base end. The second lens can have a second anterior side and a second posterior side. The second stanchion can have a second distal end connected to the second lens and a second base end. The first lens and the second lens can move laterally relative to one another during contraction of the ciliary muscle in a vertically-extending plane containing the optic axis of the eye and substantially centered in the eye.

An accommodating intraocular lens assembly can include lenses and stanchions. The lenses can be configured for positioning in an eye and have respective anterior and posterior sides. The stanchions can have respective distal ends connected to one of the lenses and respective base ends. The base ends can be configured for positioning within a capsular bag of the eye, in a ciliary sulcus, or on the ciliary muscle of the eye. Contraction of the ciliary muscle moves the base ends towards a central optic axis of the eye. The stanchions can be configured such that at least one of the lenses rotates relative to the other about the central optic axis in response to contraction of the ciliary muscle. In one or more other embodiments, the lenses can move laterally relative to one another during contraction and include a plurality of sub-lenses with different levels of additive optical power.

An accommodating intraocular lens with variable optical power, comprising at least two optical elements, at least one of which is movable relative to the other in a direction perpendicular to the optical axis, wherein the optical elements form a lens with different optical power at different relative positions of the optical elements. At least two of the optical elements of the lens comprise at least one additional optical correction surface, which correction surfaces are adapted for simultaneous variable correction of one or more optical aberrations of the natural eye in which the degree of correction depends on the relative position of the optical elements.

An accommodating intraocular lens implant is provided that is shaped so as to be assemblable into an assembled state in situ in a capsular bag of a human eye, and includes an anterior floating lens unit, which comprises an anterior lens; a posterior lens unit, which comprises a posterior lens; an anterior rim; levers, arranged to move the anterior floating lens unit toward and away from the anterior rim, in an anterior-posterior direction; and a circumferential rim, which is attached to the levers. The lens implant is arranged such that in the assemble state: elastic potential energy is stored in the lens implant as a result of deformation of the lens implant during a transition from a fully-accommodated state to a fully-unaccommodated state, and at least 50% of the elastic potential energy stored in the lens implant as the result of the deformation is stored in the circumferential rim.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (V-VIS) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods may optically move, at a sampling rate between 50 hertz and 50 kilohertz, one or more apertures anterior to a retina between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

The present invention provides an arrangement (600) for an artificial eye lens. The arrangement comprises at least two ring-shaped elements (610) and a plurality of arched ribs (620). The plurality of arched ribs connects the two ring-shaped elements. The ring-shaped elements and plurality of arched ribs form a space for housing the artificial eye lens. The ring-shaped elements arc moveable with respect to each other along a common axis (x). It comprises further a collapsible tape (64) for define a maximum range of deformation of the arrangement.
