| titleOfInvention | Contact and intraocular lenses containing ultraviolet absorbers and method of their production |
| abstract | The invention concerns contact and intraocular lenses formed by a polymer from 89 to 99.6 % of vinyl monomers, 0.2 to 6 wt.% of polymerizable absorbers of ultraviolet radiation, 0.1 to 3 wt.% of a crosslinker and 0.1 to 2 wt.% of a polymerization initiator. As vinyl monomers, the monomers are used selected from the group comprising alkyl acrylates and methacrylates, hydroxyalkyl acrylates and methacrylates, fluoroalkyl acrylates and methacrylates, (alkyloxy)alkyl acrylates and methacrylates, (acyloxy)alkyl acrylates and methacrylates, (acylamino)alkyl acrylates and methacrylates, (alkylsulfinyl)alkyl acrylates and methacrylates, (alkylsulfonyl)alkyl acrylates and methacrylates, tris(alkyloxy)silylalkyl acrylates and methacrylates, N-vinylpyrrolidone, N-vinylpiperidone and their combinations. As polymerizable absorbers of ultraviolet radiation, substances selected from the group of substances comprising substances of general formula (I) or (II) are used where R1, R2 are hydrogen, acryloyloxy, methacryloyloxy, (acryloyloxy)alkyloxy, (methacryloyloxy)alkyloxy, 3-(methacryloyloxy)-2-hydroxypropyloxy, vinyl, allyloxy, (acryloylamino)methyl, (methacryloylamino)methyl groups, R3, R4 are hydrogen, hydroxy, halogen, cyano, alkyloxy, alkyl, (alkyloxy)alkyl, hydroxyalkyl groups, the alkyls being alkyl groups with 1 to 4 carbon atoms or (III) or (IV), where R is acryloyl or methacryloyl group, or their mixture. As cross-linking agents, substances are used selected from the group comprising acrylic and methacrylic esters of dihydric alcolhols, amino alcohols, amines, allyl acrylates and methacrylates and diallyl esters of dicarboxylic acids and as polymerization initiators, common azo and peroxy initiators and initiators cleavable by UV radiation. |
