Plug (tear) ducts is a treatment in which Dr. Bender uses plugs to block the drainage canals of the eye when a patient has low tear volume in their eyes. It takes about ten minutes.
A tiny (0.3mm) collagen or silicone plug is inserted into the punctum or drainage canal located in the nasal corner of each eye. He puts one in the upper and one in the lower duct on each eye. This helps boost the amount of tears in a patient’s eye whereby the eyes will feel less.
