My two year old son is having a minor operation tomorrow morning: one of his tear ducts has been blocked for over a year, which makes it prone to infection (although he hasn’t had one). The only symptom that anything is wrong is tears running down one side of his face occasionally.
A surgical probe takes about 10 minutes. A thin, blunt metal wire is gently passed through the tear duct to open any obstruction. Sterile saline is then irrigated through the duct into the nose to make sure that there is now an open path. Infants experience no pain after the probing.
He has to be given general anesthesia.
Being a parent is hard on the nerves.
