    Abstract: 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 dual optic intraocular lens which redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The intraocular 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 intraocular lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the intraocular 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.

    Abstract: A lens in accordance, with the present invention includes an switchable cell consisting of optical substrate with diffraction surface, elastic film in contact with the diffraction surface of the substrate, optical fluid that fills the space between the film and diffraction surface and the mean to transfer the optical fluid in and out of the space between the film and diffraction surface. The refractive index of the optical fluid matches the refractive index of the optical substrate. The switchable cell changes focus positions between refractive focus in relaxed state when the pressure at both sides of the film is the same and diffraction focus when the optical fluid is transported from the space between the film and optical substrate for the film to largely conform to the diffraction surface shape of the optical substrate.

    Abstract: Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include a circular surface structure which acts as a diffractive or phase shifting profile. In some cases, a single ring IOL includes an anterior face and a posterior face, where a profile can be imposed on the anterior or posterior surface or face. The profile can have an inner portion such as a micro structure or central echelette, and an outer portion. Between the inner portion and the outer portion, there may be a transition zone that connects the inner and outer portions.

The lens also includes a monofocal diffractive structure disposed on one of said surfaces for providing a diffractive focusing power. The lens further includes at least one multifocal diffractive structure disposed on one of said surfaces for providing a plurality of diffractive focusing powers. The multifocal diffractive structure is adapted to provide chromatic aberration compensation for near vision.

    Abstract: In one aspect, the present invention provides a method of correcting vision, which comprises determining a residual accommodation exhibited by a natural, crystalline lens (34) of an eye (32), and selecting a multifocal intraocular lens (IOL) (20, 36), which exhibits a far-focus optical power (e.g., in a range of about -15 to about +50 Diopters (D) ) and an add power (e.g., in a range of about ID to about 4 D), for implantation in the eye while retaining the natural lens. The add power of the IOL is selected as a function of the residual accommodation such that a combination of the IOL and the natural lens provides a visual contrast greater than about 10% at a spatial frequency of about 20 cycles/degree for viewing objects at a distance greater than about 30 cm from the eye.
