Abstract
Presently, only indirect methods exist to monitor protein contamination of polymeric contact lens surfaces. This study, based on a fiber optic sensor, proposes a new quantitative and dynamic measurement technique to address this problem. Comparative contamination studies on three representative proteins: γ globulin, bovine serum albumin (BSA) and ovalbumin (molecular weight 240,000, 60,000 and 45,000), using a new tensiographic method, have been developed for a polymethylmethacrylate (PMMA) substrate.
