Abstract:
The present invention relates to ionic silicone hydrogel contact lenses which comprise at least one pharmaceutical or nutriceutical component and are formed from reaction mixtures comprising a mixture of slow-reacting hydrophilic monomers, including at least one slow-reacting ionic monomer, at least one silicone-containing component and at least one hydroxyl-containing component, wherein the ratio of the slow-reacting hydrophilic component half lives to the silicone-containing component half life is at least 2.
