The invention provides in one form a macromonomer comprising a polysiloxane copolymer having a backbone structure derived from siloxane monomer units that are substituted or unsubstituted arylsiloxanes, arylalkylsiloxanes, alky(alkyl)siloxanes of the general formula -R1R2SiO- and wherein the terminal groups of the copolymer backbone include crosslinkable groups and wherein pendent from the backbone are at least two crosslinkable groups. The macromonomer may be cured in vivo by ultraviolet or visible light. The invention includes intraocular lenses formed by such macromonomers.
L'invention concerne, selon un aspect, un macromonomère qui comprend un copolymère polysiloxane présentant une structure de squelette dérivée d'unités de monomère siloxane qui sont des arylsiloxanes, arylalkysiloxanes, alky(alkyl)siloxanes substitués ou non substitués de formule générale -R¿1?R¿2?SiO-, les groupes terminaux du squelette du copolymère comprenant des groupes réticulables, et au moins deux groupes réticulables étant placés latéralement par rapport au squelette. Ledit macronomère peut être chauffé in vivo par une lumière ultraviolette ou visible. L'invention concerne également des lentilles intraoculaires formées au moyen desdits macronomères.
