Details on study design:
Eyes were rinsed with physiological saline 24 hours after instillation.

Eyes were inspected for integrity before the testing. A solution of fluorescein, sodium salt (0.01%) was dropped into the eye. Then the cornea was investigated using UV radiation 24 hours before application. Afterwards eyes were rinsed.

24 and 72 hours after application eyes were examined for integrity in the same manner.
