  • Patent number: 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.

  • Patent number: 11464672
    Abstract: Systems and methods are provided for generating and applying biomimicry tear film layers to a cornea surface. An example method includes forming a multiple layered tear film that are optically transparent, ultra-thin, and smoothly conforming to cornea surface. The multiple layered tear film can include a biomimicry adhesive layer, a biomimicry aqueous layer, and a biomimicry lipid layer. An atomizer/nebulizer/micronizer can be used to generate and applying the biomimicry tear film layers.

  • Patent number: 11253395
    Abstract: Systems and methods are provided for generating and applying artificial tear film layers to a cornea surface. An example method includes forming an artificial tear film that is optically transparent, ultra-thin, and smoothly conforming to cornea surface. The artificial tear film includes a lipid layer that prevents evaporation of moisture from the cornea (e.g., from the underlying aqueous layer of the artificial tear film, and/or from the natural tear film on the cornea, etc.). A dispenser, such as an atomizer/nebulizer/micronizer, can be used to generate and applying the artificial tear film layers, especially the lipid layer, with reduced dispensing volume and average droplet size, etc., such that the deposit thickness of the artificial tear film layers remains thin and better spreads and conforms to the surface of the cornea, as compared to the results of conventional eye droppers dispensing conventional artificial tears.
