The invention includes a method for the passivation of the surface of an intraocular lens, wherein the surface includes Br&#xf6;nsted sites. The intraocular lens is dipped into a solution of a fluoroalkyl silane having the general formula: R&#x2014;(CH)&#x2014;Si&#x2014;(O&#x2014;R). The residue R is selected from the group of H, CH, CHand CHand the fluoroalkyl residue Ris selected from the series CF(CF), with m=3 to 11 and n=0 to 4. The Br&#xf6;nsted sites on the surface are thereby deactivated by formation of Si&#x2014;Q&#x2014;bonds.
