Abstract
The invention contemplates a copolymer which is a graft or block copolymer useful to change wettability and surface characteristics of biological surfaces. Methods for use of these formulations and coatings to change wettability and sterically stabilize, and lubricate biological surfaces in a subject, for example, in the treatment of dry eye syndrome, and to prevent adherence of unwanted proteins, for example in the treatment of contact lens intolerance, are provided.
