Beschreibung
Zusammenfassung:	The present invention relates to biomedical devices, in particular ocular devices, comprising: a bulk material resulting from the co-polymerization of funtionalized perfluoroalkylpolyether (PFPE) macromonomers and zwitterionic substituted ethylenic units a surface activated with a glycoprotein or collagen said surface being coated with a functionalized polyethylene glycol (PEG). The coating allows for adhering or crosslinking to tissues, so that said devices may be used, e.g., as ready-to-use corneal onlays in ophthalmic surgery.
