Summary: | A cationic contact lens is described as well as methods of manufacturing the same. The cationic contact lens includes a polymeric lens body that is the reaction product of a polymerizable composition that includes at least one siloxane, at least one nonionic hydrophilic monomer and at least one acyclic tertiary amine monomer. The cationic contact lens can be an unworn sterile silicone hydrogel contact lens. The contact lens is capable of substantially linear release of a releasable anionic agent and the at least one acyclic tertiary amine monomer facilitates uptake and/or sustained release of the releasable anionic agent by the polymeric lens body. The contact lens can be present in a sealed contact lens package. The sealed contact lens package can include at least a) a base member having a cavity; b) a contact lens packaging solution in the cavity; c) a unworn sterile contact lens immersed in the contact lens packaging solution in the cavity with the releasable anionic agent present; and d) a cover that forms a liquid-tight seal with the base member. |
