Exchangeable optics and therapeutics
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 or therapeutic and can include magnetic material. The supporting structure can include haptics and a main structure that physically supports the exchangeable optic or the therapeutic that is coupled via the one or more couplers. In some cases, 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. The therapeutic can be in the form of a magnetic particle.
INTRAOCULAR ACCOMMODATING LENS AND METHODS OF USE
Described herein are intraocular lenses and methods of implantation. In one aspect, the lens includes a shape changing optical element; a force translation element having a first end region coupled to the optical element and a second end region extending towards a ciliary structure, and an attachment portion coupled to the second end region of the force translation element and configured to contact the ciliary structure. The force translation element is configured to functionally transmit movements of the ciliary structure into a force exerted upon the optical element to effect an accommodating and a disaccommodating change of the optical element.
Fresnel piggyback intraocular lens that improves overall vision where there is a local loss of retinal function
Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the piggyback lens can be configured to improve or reduce optical errors at the location on the peripheral retina. One or more surfaces of the piggyback lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles. One or more surfaces of the piggyback lens can be faceted.
Intraocular lens implant for the correction of vision
Novel intraocular lenses comprising at least one haptic having a shape memory alloy with a transition temperature substantially higher than the human body temperature, the shape memory alloy being post-surgically, selectively adjustable with a laser beam.
Intraocular lens and manufacturing method therefor
The present invention relates to an aspherical multifocal intraocular lens with large depth of field, the intraocular lens having an anterior optical surface and a posterior optical surface, wherein one optical surface is distributed with an aspherical surface which plays a role of expanding the depth of field, and the other optical surface is distributed with a multifocal structure which plays a role of providing two or more focal points. The aspherical surface provides a depth of field matching with an absolute value of a difference in refractive power of at least one pair of adjacent focal points of the two or more focal points provided by the multifocal structure. The aspherical surface, on the one hand, allows a continuous visual range between the focal points and, on the other hand, extends near vision in the direction of near focal point through the depth of field, thereby enabling continuous, uninterrupted full-range vision and adequate near vision. The present invention also relates to a method for manufacturing an intraocular lens. The present invention also relates to an artificial lens, and more particularly to an artificial lens that makes use of excessive resolution to achieve focal extension. The present invention also relates to a method for manufacturing an artificial lens.
Optical Devices Having Partial or Incomplete Optic and Associated Methods
An optical device including a partial or incomplete optic configured operatively as an add-on (e.g., supplemental lens/optic) for an (existing) optical element or system, the partial or incomplete optic having an active area configured in relation to the optical element or system such that the partial or incomplete optic controls or changes foci of light incident upon or provided to the active area, but does not control or change foci of light bypassing optically relevant portions of the partial or incomplete optic, and associated methods for enhancing vision.
INTRAOCULAR PSEUDOPHAKIC CONTACT LENSES AND RELATED SYSTEMS AND METHODS
An apparatus includes an intraocular pseudophakic contact lens having a first optical lens, multiple projections extending from the first optical lens, and multiple anchors partially embedded in or configured to pass through the projections. The anchors are configured to pierce lens material forming a second optical lens of an artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. Different portions of the first optical lens have different refractive powers such that a first portion of the first optical lens has a first refractive power and a second portion of the first optical lens has a second refractive power different from the first refractive power.
Phakic intraocular lens
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.
Intraocular pseudophakic contact lens with mechanism for securing by anterior leaflet of capsular wall and related system and method
An apparatus includes an intraocular pseudophakic contact lens having an optical lens and haptics extending radially from the optical lens and configured to be inserted under an anterior leaflet of a capsular wall in an eye in order to capture and confine the haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against an artificial intraocular lens in the eye. Anterior surfaces of the haptics are configured to contact an inner capsular wall surface at the anterior leaflet. Posterior surfaces of the haptics include ridges configured to capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. Different portions of the optical lens provide different amounts of magnification such that a first portion of the optical lens provides a first amount of magnification and a second portion of the optical lens provides a second amount of magnification.
