    摘要: Silicone hydrogel contact lenses are formed from the reaction product of a polymerizable composition comprising at least one acrylate-containing siloxane monomer, at least one hydrophilic vinyl-containing monomer, and at least one vinyl-containing cross-linking agent, wherein the polymerizable composition has a molar ratio of total amount of hydrophilic vinyl-containing monomer to total amount of acrylate-containing siloxane monomer of from 5:1 to 30:1, respectively. The silicone hydrogel contact lenses have good manufacturing processability, can be manufactured without the use of alcohol solvents, and have excellent surface wettability.

    摘要: Silicone hydrogel contact lenses that are derived from a polymerizable composition including a first siloxane monomer represented by formula (3): wherein m of formula (3) represents one integer from 3 to 10, n of formula (3) represents one integer from 1 to 10, R1 of formula (3) is an alkyl group having from 1 to 4 carbon atoms, and each R2 of formula (3) is independently either a hydrogen atom or a methyl group; and at least one vinyl ether-containing cross-linking agent are described. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described. In one example, the batches of silicone hydrogel contact lenses are dimensionally stable, and the method of making is a method of making dimensionally stable silicone hydrogel contact lenses.
