Process for producing controlled drug-release contact lens, and controlled drug-release contact lens thereby produced

摘要

A process for producing a controlled drug-release contact lens, containing a first member which forms a front fact of the lens and a second member which forms a rear face of the lens, the first and second members defining a space in the contact lens, which entails a) preparing the first and second members from a non-crosslinked polymer; b) bonding the prepared first and second members by melt pressing; and c) crosslinking the bonded members by hydration treatment, wherein the non-crosslinked polymer is obtained from a polymerizable methoxy silicone compound and another monomer copolymerizable therewith.
