Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I would say about 5-7 days after the ointment has stopped and the ulcer is healed you can have your vet to the Schirmer Tear Test (STT) to see if Bella has dry eye. I hope this helps!

    Hello and thank you for your post! Typically say to wait a minimum of 1 hour before performing the test but on average I run the test 3 or more hours after the last dose with how scheduling ends up for most people and this has never resulted in false readings.
