Patent ID: 11801162

Abstract:
An apparatus for treating dry eye, comprising composition chambers respectively containing a first composition and a second composition, wherein the first composition includes 95%-100% of aqueous substances and the second composition includes 95-100% volume of non-aqueous substances; and an air pump that is fluidically connected to the composition chambers and sequentially generates and propels the mists of the first composition and the second composition to a surface that corresponds to a cornea of an eye. The first mist, including droplets of the one or more aqueous substances forms a first film layer that corresponds to an aqueous layer of an artificial tear film, the second mist has a volume within a range of 0.1-3 microliters, and includes droplets of the one or more non-aqueous substances forms a second film layer that corresponds to a lipid layer of the artificial tear film with a thickness within a range of 10 nm-200 nm.
