US Patent 7241009 Crosslinking of silicones presence of functionalized silicones

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.
