I would use the antibiotic cream first and wait a bit for the other. I do not think one would need 2 types of dry eye ointment since lacrilube is a dry eye gel. The visco tears could be used later when the lacrilube seems less effective? We would wait 5-10 minutes when put eye drops in people who are on eye medications and used 2 kinds of meds.
Just my thought anyway. Cheryl R
