This is the predominant tear duct drainage operation for cases of nasolacrimal duct obstruction or blocked tear ducts, a relatively common cause of watery eyes. This surgery can be performed under local anaesthesia (with sedation) or general anaesthesia, and the patient usually goes home on the same day.
For rare cases of canalicular obstruction causing watery eye.
For cases where lacrimal pump function is impaired.
Surgery may be indicated once the cause is determined
