Abstract:
1. A method of modifying a surface of an intraocular lens, the surface of which comprises Brönsted sites, the method comprising contacting the surface of the lens with a solution of a fluoroalkyl silane of general formula wherein R is selected from the group of H, CH 3 , C 2 H 7 , and R F is CF 3 (CF 2 ) m , with m=3 to 11 and n=0 to 4, whereby the fluoroalkyl silane is tethered to the surface by formation of Si—O—bonds at the Brönsted sites on the surface, and the modified surface of the intraocular lens has a fluorine content that is between 2% by weight and 15% by weight, and an oxygen content from 25.1% to 31.3% by weight, as measured by x-ray photoelectron spectroscopy.
