The invention discloses a
high oxygen-permeability fluorosilicone hydrogel
contact lens material and a preparation method thereof. The
high oxygen-permeability fluorosilicone hydrogel
contact lens material is obtained by crosslinking copolymerization of a
fluorine-containing polysilicone
monomer with hydrophilic groups and ends capped by
methacrylate and one or more hydrophilic monomers and
siloxane monomers initiated by
ultraviolet light or heat. The content of a fluorosilicone amphiphilic
monomer in the mixed monomers is 20%-60%. The preparation method comprises the following steps: evenly mixing the fluorosilicone amphiphilic
monomer, the hydrophilic monomers, the
siloxane monomers, a crosslinking agent, an initiator and a
diluent, injecting the mixture into a mold, initiating
polymerization by
ultraviolet irradiation or heat, then demolding, removing unreacted monomers or oligomers, and immersing in water to obtain hydrogel. The hydrogel material has
high oxygen permeability, wettability, proteinosis resistance and the like, and is a
corneal contact lens with excellent properties.
