The invention relates to a method for the passivation of the surface of an intraocular lens, the surface of which comprises reactive Brönsted sites. Conventional methods of the above type create changes on the original material and exhibit undesired interactions with medical adjuncts. The aim of the invention is to describe a method in which the intraocular lens is passivated and coated in an advantageous manner and only minimal changes are brought about on the original material. Said aim is achieved, whereby the intraocular lens is dipped in a solution of a fluoroalkylsilane of general formula RF—(CH2)n—Si—(O—R)3, where R═H, CH3, C2H5, or C3H7 and the fluoroalkyl group RF═CF3 (CF2)m where m=3 to 11 and n=0 to 4, whereby the Brönsted centres on the surface are deactivated by formation of Si—O bonds.
