Increased Pseudomonas aeruginosa adhesion following air drying of etafilcon A soft contact lenses

The purpose of this study was to determine the changes in bacterial adhesion resulting from air-drying soft contact lenses. An in vitro study was conducted on four sets of identical, unworn etafilcon A soft contact lenses, air-dried for varying periods of time. These lenses were placed in a bacteria...

Description
Summary:	The purpose of this study was to determine the changes in bacterial adhesion resulting from air-drying soft contact lenses. An in vitro study was conducted on four sets of identical, unworn etafilcon A soft contact lenses, air-dried for varying periods of time. These lenses were placed in a bacterial suspension, rinsed, ground, and plated in order to determine bacterial adhesion. The increased bacterial adhesion to these high water content, ionic lenses was statistically significant following five minutes of drying. Reversal of the effect was noted after rehydration. Soft contact lens drying results in increased bacterial adhesion.
