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.
