A new class of silicone monomers, providing transparent materials and imparting hydrophilic properties have been developed. These materials are incorporated into ophthalmic devices such as soft and rigid gas permeable (RGP) contact lenses. These new silicone monomers include Polyhedral Oligomeric Silsesquioxane (POSS) with two polymerizable groups and six organofunctional groups. These types of structures incorporate at least two available sites for polymerization allowing for the incorporation of the silsesquioxane cage into the backbone of a macromolecule. Additional functional sites allow the design of specific chemical features which address needed material properties.
