other suitable organic diluents would be apparent to a person of ordinary skill in the art the organic diluent is included in an amount effective to provide the desired effect generally the diluent is included at 5 to 60 by weight of the monomeric mixture with 10 to 50 by weight being especially preferred according to the present process the monomeric mixture comprising at least one hydrophilic monomer at least one hydrophilic siloxy containing monomer of the invention herein and optionally the organic diluent is shaped and cured by conventional methods such as static casting or spincasting lens formation can be by free radical polymerization such as azobisisobutyronitrile aibn and peroxide catalysts using initiators and under conditions such as those set forth in u s pat no 3 808 179 incorporated herein by reference photoinitiation of polymerization of the monomer mixture as is well known in the art may also be used in the process of forming an article as disclosed herein colorants and the like may be added prior to monomer polymerization subsequently a sufficient amount of unreacted monomer and when present organic diluent is removed from the cured article to improve the biocompatibility of the article release of non polymerized monomers into the eye upon installation of a lens can cause irritation and other problems unlike other monomer mixtures that must be extracted with flammable solvents such as isopropyl alcohol because of the properties of the novel hydrophilic siloxane.
