    摘要: 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.

    摘要: The present invention relates to an aqueous bubble solution. The solution has at least a surfactant that produces micelles in an aqueous solution, along with an ionic, hydrophobic or hydrogen bonding agent that interacts with the surfactant. When the bubble solution is formed into a bubble the bubble provides a first predetermined effect other than just being formed and popping.
