Nasolacrimal Duct Obstruction (NLDO)

Nasolacrimal Duct Obstruction is a blocked tear duct in the lacrimal gland, which produces tears that drain from the eye into the nose. When this duct is blocked, it can cause excessive tearing and mucous discharge, which can lead to recurrent red eyes and infections.

Surgery Can Help

  • Discontinue excessive tearing and mucus discharge
  • Reduce the risk of red eyes and infections
  • Resume functionality of the lacrimal gland that produces tears

How is the Surgery Performed?

The cause of the blocked tear duct will determine which treatment is right for you. A small silicone tube is placed in the new tear duct for three months to keep it open. The procedure may be performed through a one-centimeter skin incision in the skin or through the nose, without a skin incision. The procedure takes about 30 minutes and is performed in the operating room with IV sedation or general anesthesia. Postoperative discomfort is minimal, and most patients can return to normal activities within a week. Makeup and contacts can usually be worn after a week.
