Abstract: Therapeutic contact lenses (TCLs) have proved to be an effective tool in the management of a wide variety of ophthalmic disorders. Conditions recalcitrant to other treatment modalities may heal readily with the use of a TCL. With proper patient selection, observation and management, TCLs provide an extremely effective therapeutic adjunct. Drug delivery through therapeutic contact lenses enhances the bioavailability of drug by controlled and extended release on the eye surface and enhances the residence time of drug in eye cavity. The contact lenses prevent the drug from being lost to tear drainage by releasing the drug into tear layer on the contact lens, where it ultimately diffuses into the eye. In this review focus has been made on developing drug eluting contact lens using three techniques like nanoparticle encapsulated therapeutic contact lens, molecularly imprinted therapeutic contact lens and Particle-laden soft contact lenses.
