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.
