Patent abstract
This invention relates to an emulsion composition for the formation of an artificial tear film over the ocular surface of the eye capable of providing mechanical lubrication for the ocular surface while reducing evaporation of fluid therefrom. The emulsion is desirably in the form of a meta stable emulsion and is characterized by the use of a surfactant comprising a combination of a primary and secondary surfactant where the primary surfactant permits formation of the emulsion and the secondary surfactant permits autoclaving of the surfactant. The invention also includes a method for the formation of such an emulsion.
