    摘要: Methods and materials are disclosed for the production of optical elements, in particular intraocular lenses (IOL) that incorporate any amount (0 to 99%) of refraction and/or shape modulating compound into a substantially crosslinked first polymeric matrix. The materials produced according to the inventive methods exhibit certain rheological parameters useful in defining medical lenses. These medical lenses have the ability to change their refractive power via changing the refractive index and/or by altering the shape by stimulus induced polymerization.

    摘要: The invention relates to a novel composition for improving the accommodation capability of an intraocular lens (IOL). In one embodiment, the composition can be injected into the capsular bag where it surrounds an implanted IOL anchoring the IOL to the capsular bag. Alternatively, for anterior chamber IOLs, the composition can be injected into the bag behind the lens. The material has a refractive index similar to that of aqueous thereby reducing any potential interference with the implanted IOL. Accommodation is provided by the mixture of the crosslinked composition caused by the flexing of the muscles. The novel composition is particularly useful in enhancing accommodation for adjustable intraocular lenses.

    摘要: The present invention relates to lenses that are capable of post-fabrication power modifications. In general, the inventive lenses comprise (i) a first polymer matrix and (ii) a refraction modulating composition that is capable of stimulus-induced polymerization dispersed therein. When at least a portion of the lens is exposed to an appropriate stimulus, the refraction modulating composition forms a second polymer matrix. The amount and location of the second polymer matrix may modify a lens characteristic such as lens power by changing its refractive index and/or by altering its shape. The inventive lenses have a number of applications in the electronics and medical fields as data storage means and as medical lenses, particularly intraocular lenses, respectively.
