    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.

    摘要： A high refractive index composition comprising a reaction product of one or more first organic compounds capable of undergoing polymerization and one or more second compounds with high refractive index, and the method of making and using the composition. A composition comprising an organic compound obtained by coupling two reactive groups (a) and (b), wherein a. the reactive group (a) is Y—(CH2)n-M(O—R)3, wherein R is CH3, C2H5, C3H8, C4H10; and Y is —NH2, —COOH, —NCO, or epoxy; and wherein M is selected from the group consisting of Ti, Zr, V, Mg, Al, Mn, Sb, Ba, Ca, Ce, Si, and Sn; and b. the reactive group (b) is selected from the group consisting of carbazole, fluorene, imidazole with one or more functional groups selected from —OH, —NH2, —COOH, —NCO, -epoxy, -vinyl, -acrylic, -acyl, -alkyl, -halide, -amino, -ketone, -allyl, -allylic, -thiol, -isocyanate, and a mixture thereof; and the method of making and using the composition.
