Watery eyes are usually a sign of blocked tear ducts resulting from infection, injury, tumor, or most commonly allergies and sinus problems. Tear duct surgery (dacryocystorhinostomy) may be performed to open or bypass the duct and allow the tears to drain directly into the nose. Tear duct surgery can be performed through a small incision in the corner of the eye or by use of endoscopic surgery, which uses a tiny camera placed through the nose. One can expect the use of silicone tubes (not very visible to the public) placed from tear duct ending in the nose to hold the passageway open during the healing phase for two months. After surgery there could be slight bleeding from the nose for several hours. The area around the eye would be black and blue and swollen for about a week. Once the tube is removed the eye should stop watering, often times with signs of dry eye until the eye acclimates to its new environment.
