Abstract
High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise two or more aryl hydrophobic monomers and a non-polymerizable propylene oxide-ethylene oxide-propylene oxide block copolymer surfactant having a molecular weight of approximately 3600 and approximately 40% ethylene oxide units by weight. The copolymers have a reduced tendency to form glistenings when stored in water at physiological temperatures compared to similar copolymers lacking the non-polymerizable surfactant.
