Irritant / corrosive response data:
No corneal or iridal effects were noted. Moderate conjunctival irritation was noted in all treated eyes at the 1-hour observation with minimal conjunctival irritation noted in all treated eyes at the 24-hour observation and one treated eye at the 48-hour observation. Treated eyes appeared normal 48 to 72 hours after treatment.
