Correction of defects in the eye and compositions therefor

摘要

A composition for forming in vivo a lens in an eye comprises silicone polymer and is curable at body temperature to form an optically clear lens which remains so in the presence of physiological fluids. The composition is generally a curable viscous liquid comprising (a) a crosslinkable siloxane polymer, (b) a crosslinker, and (c) a crosslinking catalyst for injecting into the lens capsule of the eye from which the natural lens has been removed.
