In vitro evaluation of inflammatory cell response after CF4 plasma surface modification of poly(methyl methacrylate) intraocular lenses

Abstract

Nd granulocyte adhesion on the surface-modified IOL than on the untreated IOL (P < .01). The x-ray photoelectron spectroscopy analysis of the CF4 plasma surface modification demonstrated that new compounds containing fluorine were homogeneously grafted onto the PMMA lens surface, resulting in a marked increase of contact angle. These in vitro results must be confirmed by in vivo studies of CF4 plasma surface modification of IOLs. 1Reprint requests to D.
