There are a number of different procedures that may be required to correct a watery eye which will be discussed with you in clinic. If you present with a watery eye we may need to syringe your tear duct. The aim is to find out whether or not you have a blockage in the tear system. In over a third of cases a watery eye is related to a blockage in the passage way between the eyelid and the nose. This passage way normally drains the tears from the eye into the nose at which point the tears pass into the throat and is known as the naso-lacrimal or tear duct. The standard treatment for nasolacrimal duct obstruction (NLDO) is a dacryocystorhinostomy (DCR) procedure. This effectively bypasses the blockage in the tear duct by making a small hole in the bone on the side of your nose. The tears can then drain into the lacrimal sac and into the nose via newly fashioned pathway. This surgery can be performed either through a small incision on the side of the nose (external approach) or by using specialised endoscopes via the nose (endoscopic approach). In some cases the punctum (the entrance to the tear duct) is too small. This may prevent the tears from draining which can give you a watery eye. When punctal stenosis is present we may need to enlarge your punctum by excising a small part of the tear duct. This is called a punctoplasty.
