N- SILICONE HYDROGELS COMPRISING N-VINYL AMIDES AND HYDROXYALKYL METHACRYLATES OR METHACRYLAMIDES

摘要

The present invention comprises the steps of reacting a reactive mixture comprising at least one silicon-containing component, at least one hydrophilic component, and at least one diluent to form an ophthalmic device having a forward contact angle of less than about 80 °; And contacting the ophthalmic device with the aqueous extraction solution at increased extraction temperature, wherein the one or more diluents have a boiling point at least about 10 ° higher than the extraction temperature.
