Research Summary: Soft Contact-Lens Surface Phenomena: wettability
enhancement, tear-film stability, fouling, and bacterial adhesion. For best visual acuity and comfort,
soft contact lenses must be highly wettable to
human tear. Additionally, the
lenses should be immune both to protein and lipid fouling and to bacterial
adhesion. With these goals in
mind, we have developed several in-vitro techniques to measure wettability, mimic fouling, and quantify bacterial
adhesion to soft contact lenses. We have also investigated the efficacy of
wetting agents and performed a clinical study to test the correlation among wettability, tearfilm stability
and comfort.
