Silicone resin optical devices

摘要

Optical devices such as corneal, scleral and interocular lenses are made from phenyl-containing siloxane resins. They combine a high degree of oxygen transmission with ease of fabrication inherent to hard materials, thereby providing increased wearer comfort and ease of fabrication. A typical resin is a copolymer of phenyl, vinyl and methyl siloxanes having at least about 0.2 phenyl groups per silicon.
