    摘要: An apparatus has a central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens. The lens body has at least one haptic extending from the lens body, and the central aperture has a form of a circular hole extending fully through the lens body when the apparatus is implanted in the eye. The lens body is formed from a substantially transparent material and the central aperture includes a darkened perimeter. The darkened perimeter of the central aperture includes a darkened internal wall extending through the lens body from an anterior surface to a posterior surface of the lens body.

    摘要: 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.
