The conventional teaching for lid margin disease is to use an antibiotic oint to the lid margins at bedtime along with other therapy.

Would there be any indication to use antibiotic ointment once daily for a prolonged period of time.

But I always tell them it’s for the lubricating properties of the vehicle, and patients often prefer that substance over something like lacrilube, plus medical insurance pays for it. Then they usually understand
