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 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.

The present invention is a phakic intraocular lens for implantation between an iris and a crystalline lens. The phakic intraocular lens includes a diffraction grating 5 disposed in a lens central part 2 and having circular, coaxial grooves formed thereon, and a support part 3 disposed outside the diffraction grating 5 and supporting the diffraction grating 5. A hole 6 is formed in the center of the diffraction grating 5.

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).

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.

A method of positioning an accommodating intraocular lens assembly in an eye can include implanting an accommodating intraocular lens assembly having a positive power lens in the eye. The accommodating intraocular lens assembly can also include a plurality of stanchions extending between base ends and distal ends. The base ends can be disposed in spaced relation to one another about a first arcuate periphery positioned in a ciliary sulcus of the eye. The distal ends can be disposed about a second arcuate periphery extending in a second plane positioned forward and outside of a capsular bag of the eye. The positive-power lens can be connected with the plurality of distal ends whereby a center of the positive power lens is moved along the central optic axis in response to contraction of the first arcuate periphery by contraction of the ciliary sulcus.

An intraocular lens 1 includes a lens 2 and a haptic 3 connected to the lens 2. The lens 2 is disposed behind an iris 7 in an eye of a patient. The haptic 3 has a main body 3a and first and second projections 3d and 3e. The main body 3a extends from the lens 2 outward in a radial direction about a visual axis C of the patient. The first and second projections 3d and 3e are located so as to project from the main body 3a toward spaces between a plurality of ciliary zonules 10 connecting a crystalline lens 11 and a ciliary body 8 in the eye. Accordingly, an intraocular lens and a haptic for an intraocular lens that are able to inhibit the position of a lens from being displaced are provided.

An improved posterior chamber phakic intraocular lens (PCPIL) is provided. The improved PCPIL incorporates one or more design elements that minimize or eliminate axial displacement of the PCPIL under horizontal compression.

The present disclosure relates to a posterior chamber intraocular lens with swivel haptics for capsulotomy fixation in an eye. The posterior chamber intraocular lens includes a circular optic and at least one pair of swivel haptics. The circular optic is configured to be positioned within a capsular bag of the eye. The circular optic includes plurality of positioning holes on a periphery. The at least one pair of swivel haptics is positioned on the circular optic. The at least one pair of swivel haptics is configured to be rotated away from the circular optic and fixed above an anterior capsule of the eye.

An improved posterior chamber phakic intraocular lens (PCP-IOL) having a haptic with a collar, self-adjusting struts, and lens is disclosed. Haptic or lens of the PCP-IOL may include a protected orifice. A disclosed PCP-IOL may be configured to fit anatomy of varying sizes, and may be self-centering; additionally, a PCP-IOL as set forth herein may allow peripheral aqueous flow between anterior and posterior chambers of a patient's eye.
