ABSTRACT:
A composition which is hydrophobic but possesses excellent wettability comprising a copolymer of a polysiloxane and an ester of glycidyl alcohol and an organic acid. This copolymer is suitable for the manufacture of ocular membranes worn in contact with the eye which present excellent oxygen permeability and which can be worn for extremely long periods of time and then disposed of.
A method of preparing the ocular membranes is disclosed, in which the composition is placed between disposable molds and cured therein. The cured, mechanically and optically finished ocular membranes are recovered by the destruction of said molds and without secondary operations.
The ocular membrane is a flexible, oxygen-permeable, membrane, adapted to be inserted on the eye and worn thereon continuously for periods of more than one month.
