In vitro adhesion of Staphylococcus epidermidis on heparin-surface-modified intraocular lenses

Abstract

This quantitative study assessed the in vitro adhesion of Staphylococcus epidermidis on two types of intraocular lenses: conventional poly(methyl methacrylate) (PMMA) and heparin-surface-modified PMMA. Level adhesion was measured by microbiological turbidimetry. We also measured modifications in the bacterium's structural fatty acids after adhesion using gas chromatography.
