The invention relates to an ophthalmic molding such as a contact lens or
any kind of ocular prostheses comprising an organic bulk material having
covalently bonded to its surface an acceptor saccharide to which is
enzymatically attached one or more further carbohydrates. The ophthalmic
moldings of the invention have desirable characteristics regarding, for
example, adherence to the substrate, durability, hydrophilicity,
wettability or biocompatibility.
