Abstract: The invention relates to a method for hydrophilizing surfaces of polymer workpieces. The method has a step (a) of pretreating the workpiece surfaces in a high-frequency gas plasma which is produced on the basis of an inert gas in order to clean and activate the workpiece surfaces; a step (b) of precoating the pretreated workpiece surfaces with polyacrylic acid using a high-frequency gas plasma made of a gas mixture, said gas mixture being composed of an inert gas and a first gas made of biocompatible, polymerizable carboxy group-containing monomers; and a step (c) of subsequently coating the precoated workpiece surfaces using a second gas substantially containing acrylic acid monomers.

Abstract: An intraocular lens has a hydrophobic lens body (1) made of silicone, at the surface of which a hydrophilic layer (2) made of polyacrylate is provided, wherein the layer (2) is a PECVD/CVD-layer having a water contact angle of less than 10°. A process for hydrophilizing the surfaces of the intraocular lens includes steps for PECVD-pre-coating the pre-treated lens surfaces, and for c) CVD-follow-up-coating the so pre-coated lens surfaces.
