Watery Eye Surgery (Dacryocystorhinostomy)


In watery eye, a blockage usually occurs in  the lower tear drain as it passes through the bone and into the nose. This is a tiny bony canal running along the side wall of the nose. The schematic on the right shows an obstruction in green within the bony canal alongside the nose. To correct this blockage, the bony canal must be opened, and the most direct way of approaching this canal is from the inside of the nose.


dcrpostopdcrDacryocystorhinostomy (DCR) surgery is keyhole surgery performed through the nose via an endoscope, which is a surgical telescope. The surgery can be performed under local anaesthesia over a few hours as a day procedure. After surgery, a wide opening remains, allowing tears to drain directly into the nose.The schematic on the near right shows the bony canal has been opened, the blockage has been cleared, with a wide opening to prevent further blockage. The photograph on the far right shows the wide opening of the bony canal (circled in yellow) as viewed from inside the nose, with a probe passed from the eyelid into the nose.

There is no incision of the skin and therefore no visible scars, and bruising is rare. Most patients experience little or no discomfort after surgery, and often return to work within 5 days. Dr Anthony Maloof specialises in keyhole endoscopic surgery for watery eye, and uses this in ALL cases where the tear drain is blocked.
