Abstract
A method and composition for treating dry eye. The method comprises addition of a positively or negatively charged, complex phospholipid to the ocular surface of the eye. The phospholipid is desirably added in a treatment composition, preferably in the form of an aqueous emulsion. It is believed that the phospholipid component of the treatment composition permits replication of a tear film.
Claims27
An artificial tear film over the surface of an eye comprising a first layer in direct contact with the ocular surface, an aqueous layer over the first layer, and a layer of a complex phospholipid having a net positive or negative charge over the aqueous layer.
A stable aqueous emulsion eye treatment composition having a pH of from about 7.0 to 7.4 containing one or more complex phospholipids having a net positive or negative charge under conditions of use in an amount of at least 0.01 percent by weight of the total weight of the treatment composition.
A method for treating the eye comprising the formation of an artificial tear film over the eye by the topical application to the ocular surface of a treatment composition that contains one or more complex phospholipids having a net negative or positive charge under conditions of use in an amount of at least 0.01 percent by weight of the total weight of the treatment composition.
