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.
La présente invention concerne une composition d'émulsion qui permet de former un film de larme artificielle sur la surface oculaire de l'oeil servant à assurer la lubrification mécanique de la surface oculaire tout en réduisant l'évaporation du fluide de cette dernière. L'émulsion se présente de manière appropriée sous forme d'une émulsion métastable et se caractérise par l'utilisation d'un tensioactif comprenant une combinaison d'un tensioactif primaire et d'un tensioactif secondaire tels que le tensioactif primaire assure la formation de l'émulsion et que le tensioactif secondaire assure l'autoclavage du tensioactif. Cette invention concerne également un procédé de formation d'une telle émulsion.
