ABSTRACT:
New intraocular lenses, fixation member assemblies for use in such lenses and methods for making the same. In one embodiment, the present invention involves a method for producing a fixation member assembly which includes exposing a fixation member component to a first plasma at conditions effective to enhance, relative to a substantially identical fixation member component which is not subjected to the exposing step, the bondability between the fixation member component and a polymeric coating to be located on the fixation member component; and exposing the fixation member to a second plasma in the presence of at least one material selected from polymeric components, polymerizable components and mixtures thereof at conditions effective to form the polymeric coating located on the fixation member component. Enhanced bondability between the polymeric coating-containing fixation member component and the optic of the intraocular lens and/or enhanced biocompatibility are preferably provided.
