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 peripheral 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.
PATIENT INTERFACE FOR LIGHT ADJUSTABLE INTRAOCULAR LENS IRRADIATION SYSTEM
In embodiments, a light adjustable lens irradiation system for a light adjustable lens irradiation system, comprises an irradiation light source, for generating a UV light beam; an optical system, for directing the UV light beam towards a light adjustable intraocular lens, implanted into an eye of a patient; and a patient interface, coupled to the optical system, for stabilizing the eye relative to the optical system, to achieve an alignment of the light adjustable intraocular lens and the UV light beam.
Ocular systems, devices, and methods
An upgradable intraocular platform system includes (a) a substrate implantable in an eye; (b) an upgrade interface on the substrate for connection of at least one upgrade component for upgrading the platform system; and (c) a controller for controlling operation of the platform system.
Intraocular lens with dynamic pinhole
Embodiments of an intraocular lens are described. The intraocular lens includes a lens having a center and having positive or negative optical power and a pinhole mask formed on the lens. The pinhole mask includes one or more annular sections whose centers substantially coincide with the center of the lens, each of the one or more concentric annular sections having variable opacity, and a central section that is permanently transparent, the radius of the central section being adapted to allow the central section to act as a pinhole when the one or more concentric annular sections are made opaque.
Shape memory polymer intraocular lenses
A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10 C. and 60 C., inclusive, de minimiz or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.

Methods for tailoring the refractive index of lenses
Methods and devices for altering the power of a lens, such as an intraocular lens, are disclosed. In one method, the lens comprises a single polymer matrix containing crosslinkable pendant groups, wherein the polymer matrix increases in volume when crosslinked. The lens does not contain free monomer. Upon exposure to ultraviolet radiation, crosslinking causes the exposed portion of the lens to increase in volume, causing an increase in the refractive index. In another method, the lens comprises a polymer matrix containing photobleachable chromophores. Upon exposure to ultraviolet radiation, photobleaching causes a decrease in refractive index in the exposed portion without any change in lens thickness. These methods avoid the need to wait for diffusion to occur to change the lens shape and avoid the need for a second exposure to radiation to lock in the changes to the lens.
