CONTACT LENSES MADE WITH HEMA-COMPATIBLE POLYSILOXANE MACROMERS

摘要

Optically clear silicone hydrogel contact lenses are described that comprise a polymeric lens body that is the reaction product of a polymerizable composition comprising at least 25 wt.% of at least one hydroxyalkyl methacrylate; and at least 20 wt. % of at least one HEMA-compatible bifunctional polysiloxane comprising at least 6 siloxane groups and having an HLB value of at least 5 and/or a hydroxyl group content of at least 1wt.%.
