    摘要： 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 tone surface, a higher order aspheric surface, an aspheric Zeraike 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.

    摘要： A toric ophthalmic lens having substantially zero spherical aberration for a first circular aperture having a first diameter and substantially zero spherical aberration for a second circular aperture having a second diameter, the first diameter being at least 4 mm and the second diameter being at least 3 mm, the first diameter being at least 0.5 mm larger than the second diameter. A series of ophthalmic lenses, each lens comprising a same spherical power as the other lenses in the set, and a unique cylindrical power, each lens comprising (i) a first toric surface, and (ii) a second surface, at least one of the first surface and the second surface being aspheric in a meridian, the lens having substantially zero spherical aberration for all circular optical zone diameters less than 4 mm.
