Abstract:
UV-absorption method was able to determine protease activities in various kinds of enzymatic cleaners. Bioclen G and O2 had high protease activeities at room temperature and were effective for artificial protein deposits; Bioclen G is safe for the eyes because enzyme was inactivated at 70 degrees C. Both products were better enzymatic cleaners for both hard and soft contact lenses. Hydrocare-F was effective for removing artificial protein deposits. For the sake of safety against the eyes, there was a problem in that this product had too high protease activity at 90 degrees C. Protease activities were generally lower or showed great variations at 10~30 degrees C for other products. These had lower cleaning effect for artificial protein deposits on rigid gas permeable contact lenses.
