VIBRATIONAL SPECTROSCOPIC STUDY OF DISPOSABLE SOFT CONTACT-LENSES - CORRELATIONS WITH THE BACTERIAL ADHESION ON THEIR SURFACE

Raman and infrared spectra of two types of disposable soft contact len ses are presented and discussed in order to correlate the chemical str uctures of the polymers to bacterial adhesion on their surface. The re sults of the adhesion study show that Staphylococcus aureus adheres be tter to more hydrophilic lenses. The spectroscopic results point out t hat the different chemical structures of the polymers can explain not only the different water amounts in the lenses, but also play an impor tant role on the adhesion capability of Staphylococcus aureus.
