1. A method for improving the wettability of a medical device, comprising:
- (a) providing a medical device formed from a monomer mixture comprising a hydrophilic device-forming monomer including a copolymerizable group and an electron donating moiety, and a second device-forming monomer including a copolymerizable group and a reactive functional group; and
(b) contacting a surface of the medical device with a wetting agent including a proton donating moiety reactive with the functional group provided by the second device-forming monomer and that complexes with the electron donating moiety provided by the hydrophilic lens-forming monomer.
