Extraocular ophthalmic preparations or devices useful as therapeutic, diagnostic lubricating or protective agents are disclosed. Perfluorocarbon films or gels are employed extraocularly as contact lenses. Liquid perfluorocarbons and substituted derivatives are the active components of the ophthalmic preparations. The neat perfluorocarbon liquids are not aqueous, wherefore, isotonicity and pH need not be considered in their preparation. Liquid sterility may be maintained without the addition of preservatives. Cornea and conjunctiva surfaces are provided with greater amounts of oxygen when the perfluorcarbon liquids are employed as eye drops. Transparent contact lenses having oxygen permeable properties are provided by the extraocular perfluorocarbon films or discs. Emulsions of perfluorocarbons in water are also suitable for all of the above uses and as carriers for drugs, antibiotics, hormones and therapeutic agents.
