Abstract
The present invention generally relates to a method of modifying the surface of substrates such as contact lenses and other biomedical articles by at least partially coating the surfaces of such substrates with a polymeric tie layer having reactive sites. Various other moieties may then be chemically attached to the article surface by reaction of the other moieties with the reactive sites through classical chemical attachment mechanisms.
