| 摘要 |
An intraocular lens whose optic or optic and haptic are composed of a substantially soft polymer obtained by curing a composition comprising: (a) a dimethylsiloxane-phenylsiloxane copolymer having a vinyl group at each of the both terminals of the molecular chain, (b) a diorganopolysiloxane having at least three hydrosilyl groups in the molecule, and (c) an U.V. absorber. The intraocular lens obtained above has good intraocular stability, excellent biocompatibility, high optical properties and an U.V. absorbability closer to that of the human lens. By further incorporating a filler as the component (d), the intraocular lens has improved mechanical properties and higher intraocular stability. |
