Abstract:
1. A method of producing ophthalmic devices from polymeric compositions produced through the polymerization of one or more aromatic-based silyl monomers having a structure represented by wherein R is a polymerizable group; X is selected from the group consisting of C 1-10 alkylene, C 1-10 alkyleneoxy, C 6-36 arylene and C 6-36 aryleneoxy; and the R 1 groups may be the same or different selected from the group consisting of C 1-10 alkyl, C 1-20 cycloalkyl, C 6-36 aryl, C 6-36 aryl ether, C 6-36 heterocycle, C 6-36 heterocycle with one or more substituents, C 1-10 alkyl ether and C 6-36 aryloxy, with at least one R 1 group being other than a methyl group; and with at least one of said monomers having at least one non-phenyl R 1 group, comprising: casting one or more polymeric compositions in the form of a rod; lathing or machining said rod into disks; and lathing or machining said disks into ophthalmic devices.
