Disclosed are accommodating intraocular lenses with a variable power lens and a lens driver coupled to the variable power lens. The driver is arranged to be, at least partially, positioned in an accommodative structure of the eye, for example the sulcus of the eye or the capsular bag of the eye with the driver including a tapered flange which tapers towards its peripheral free end to provide translation of constrictive movement of the accommodative structure in an axial direction into movement onto the variable power lens in a lateral direction.

An exchangeable optics system includes an intraocular base that can be fixed within an eye. The intraocular base includes one or more couplers and a supporting structure. The one or more couplers releasably couple to an exchangeable optic and can include magnetic material. The supporting structure can include haptics and a main structure that physically supports the exchangeable optic. The intraocular base can include a fixed lens within or on the main structure. The exchangeable optic can include corresponding one or more couplers, which may be formed of magnetic material.

An apparatus has a central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens. The lens body has at least one haptic extending from the lens body, and the central aperture has a form of a circular hole extending fully through the lens body when the apparatus is implanted in the eye. The lens body is formed from a substantially transparent material and the central aperture includes a darkened perimeter. The darkened perimeter of the central aperture includes a darkened internal wall extending through the lens body from an anterior surface to a posterior surface of the lens body.

The present invention relates to a posterior chamber phakic intraocular lens (1) comprising a central optical part (2), a peripheral haptic part (3) having distal support elements (4) arranged for supporting the intraocular lens (1) on a ciliary zonule, elongated flexible footplates (5) mounted on the support elements (4), each having a distal lateral border (53) arranged for stabilizing the intraocular lens (1) into a ciliary body (98), and manipulation pockets (6) on a surface of the support elements (4), each being associated with one of the elongated flexible footplates (5).

Disclosed herein is an implantable accommodative IOL device for insertion into an eye of a patient, comprising an active region and a passive region. The active region has a first thickness and first refractive index, and the active region comprises an electrically responsive optical lens having variable optical power. The passive region is disposed at a periphery of the active region, and the passive region has a second thickness and a second refractive index. The second refractive index is different than the first refractive index. Thus, the light beams passing through the active and passive regions have a phase difference, thereby providing an extended depth of field.

An intraocular lens (IOL) prosthesis is implanted through one or more corneal incisions made within a predetermined surgical axis defining a plane that intersects the optical axis as well as the visual axis of the human eye. At least two looped sutures are fed through suture apertures and sutured to the sclera of the eye by which a center aperture of the prosthesis is suspended in the plane within the posterior chamber of the eye and centered on either the optical or visual axis. The prosthesis is made of a thin sheet of flexibly resilient material (e.g. silicone, polyimide, acrylic, polypropylene), and can be rectangular, triangular or of any suitable geometric shape. The center aperture has dimensions that facilitates optic capture or reverse optic capture of commercially available IOLs and includes vertex features for resisting movement of the haptics of the captured IOLs once captured therein.

An intraocular optic 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 apparatus includes an intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens includes an optical lens configured to at least partially correct a residual refractive error in an eye. The residual refractive error includes a refractive error that exists in the eye after implantation of an artificial intraocular lens in the eye. The intraocular pseudophakic contact lens also includes one or more haptics configured to be inserted under an anterior leaflet of a capsular wall in the eye in order to capture and confine the one or more haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against the artificial intraocular lens.

The intraocular aberration correction lens is shaped by an optical area that has a gradient in the chromatic dispersion value of the material or materials that shape it, in such way that said gradient is parallel to the optical axis. The net value of the chromatic dispersion in the anterior area of the lens is different from the value in its posterior area. For this, the use of a single material or various is possible. The anterior and posterior surfaces of the lens, as well as the separation between adjacent materials, if applicable, have a geometric shape so that the group comprising the intraocular lens and the eye that contains it display a correction, or significant reduction, of the optical aberrations, both the chromatic ones and the monochromatic ones on and outside the optical axis. The lens can be given areas with different optical powers in a way that enables clear and simultaneous vision at different distances.

An intraocular lens (IOL) having an optical axis extending in an anterior-posterior direction and an equator extending in a plane substantially perpendicular to the optical axis is described. The IOL includes: an elastic anterior face located anterior to the equator; a posterior face located posterior to the equator, wherein the anterior face, the posterior face, or both comprises a poly(dimethylsiloxane) elastomer having a durometer between about 20 Shore A to about 50 Shore A; and a chamber located between the anterior face and the posterior face comprising a silicone oil comprising polysiloxanes comprising diphenyl siloxane and dimethyl siloxane units, the silicone oil having a maximum viscosity of about 800 cSt at 25° C.
