Composition for treating dry eye and related methods of manufacture and methods of use
First Claim
1. A dry eye composition comprising an aqueous solution that comprises carboxy-containing polymer at a concentration from about 1 to about 1.75 percent by weight of the solution, and a single polyol at a concentration of 2, 3, or 4 percent by weight of the solution, wherein the carboxy-containing polymer has a molecular weight in a range from 90 kDa to 700 kDa, the carboxy-containing polymer comprises carboxy-containing cellulose, and the carboxy-containing polymer has a degree of substitution value in a range from 0.25 to 1, and wherein the polyol contains 2 to 6 carbon atoms.
