Abstract
Official abstract text for this publication.
A silicone hydrogel composition is disclosed. The composition includes at least one silicone macromer, a hydroxy-functionalized silicone-containing monomer, a first hydrophibic monomer and at least one crosslinker, in which the first hydrophibic monomer is N-vinyl pyrrolidone. The silicone macromer and the hydroxy-functionalized silicone-containing monomer are mutually soluble with N-vinylpyrrolidone. Silicone hydrogel contact lenses prepared from the silicone hydrogel composition are also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A silicone hydrogel composition, comprising: at least one silicone macromer in the amount of 5 to 50 wt % based on the total weight of the composition, wherein the silicone macromer has a structure of chemical formula (1): wherein X is a secondary amino group (—NH—) or an oxygen atom; Y is a secondary amino group (—NH—) or an oxygen atom; a…
