ABSTRACT:
The physical properties of highly oxygen-permeable continuous-wear contact lenses, comprising a copolymer of an organosilicone monomer, a fluoroalkyl ester monomer and a hydrophilic monomer, are improved by the further addition of a linear polysiloxane oligomeric cross-linking agent with or without neopentylglycol dimethacrylate.
