AbstractProcess for rendering silicone rubber contact lenses hydrophilic by first reacting the silicone rubber with an oligomeric siloxane containing SiH groups in the presence of a catalyst and then subjecting the resulting equilibrated silicone rubber to a reaction with an aqueous base; or a silane addition reaction with a reactant containing C=C double bonds.
