Abstract
A surface modified ophthalmic device includes a silicone ophthalmic device having a hydrophilic surface coating attached to a surface of the silicone ophthalmic device by van der Waals dispersion forces, the hydrophilic surface coating comprising a copolymer comprising (i) monomeric units derived from an ethylenically unsaturated-containing monomer having ring-opening reactive functionalities, and (ii) monomeric units derived from a hydrophilic monomer having an ethylenically unsaturated reactive group.
