  • Patent number: 8877829
    Abstract: The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to certain cationic monomers capable of polymerization to form polymeric compositions having desirable physical characteristics useful in the manufacture of ophthalmic devices. Such properties include the ability to extract the polymerized medical devices with water. This avoids the use of organic solvents as is typical in the art. The polymeric compositions comprise polymerized cationic hydrophilic siloxanyl monomers prepared by the process disclosed herein.

  • Patent number: 7832856
    Abstract: A contact lens is coated with a first polymer, such as a boronic acid-containing copolymer, having affinity to mucin, and a second polymer. The second polymer improves initial comfort of the contact lens. During wear of the contact lens, the second polymer is removed from the contact lens, by blinking and/or tear fluids, and mucin complexes with the first polymer on the contact lens surface.
