Hello and thanks for your question. When an adult has an acquired nasolacrimal duct obstruction (as you are being told you have), then the only treatment is with surgery. The surgery for this is called a dacryocystorhinostomy (DCR).
Unfortunately, the DCR sometimes tends to be like trading one problem for another. It involves making another route of drainage from the corner of the eye to the nasolacrimal duct in the nose by breaking bits of the bone in the nose and placing a glass tube called a Jones tube in that cavity for drainage. So in other words, it's not a simple procedure and can be somewhat invasive--if it is done endoscopically then it is somewhat less invasive. Some people who have this surgery have difficulty with tube sizing, keeping the tube in place, and some have continued symptoms of discharge and tearing even after the surgery. However, to date, it represents the best in surgical options for adults with acquired nasolacrimal duct obstruction.
