Thank you so much for your reply.
You can leave out Zylet since you used it already.
Blephritis caused the tear production to become abnormal - such
that cornea reflex causes the tear glands to make more tear in
in order to provide the normalize the tear film
Due to the persisting blephritis causing the abnormal tear composition, the excess tearing continues.
The goal of the Refresh is to provide a close to normal tear composition and so cause the excess reflex tearing to stop.
The goal of the Doxycycline is the kill the bacteria on the eyelid/lashes causing the bephritis.
The Zylet contain tobramycin antibiotic and mild steroid to provide added effect in the reduction of eyelid inflammation due to the blephritis. It is only for added effect, you do not have to use it. The doxycycline and the other treatments should be okay.
Once this is properly resolved, the you would only need the Refresh tears on as needed basis only, and for the rest of your life.
