What does it involve?

Dacryocystorhinostomy is a surgical procedure recommended for patients with tear duct obstruction. It consists of forming a new lacrimal duct using the patient’s own tissue.

When is it carried out?

It is carried out when the tear duct is obstructed below the lacrimal sac.

Prior Examinations

  • A full ophthalmological examination and eyelid and periocular examination.
  • Irrigation of the tear duct in the doctor’s surgery. This consists of syringing a saline solution at high pressure through the tear ducts to locate the blockage.
  • Sometimes a dacryocystogram (tear duct function test) is necessary.

During the Operation

The procedure is performed under local anaesthesia and sedation on an outpatient basis.
Silicone tubes are temporarily inserted into the tear duct during surgery. These act as a mould for the new tear duct so that the tears drain properly after the post-operative period.

After the Operation

  • The affected eye is occluded for 24 hours, after which the surgeon examines the patient.
  • The patient must take antibiotics and oral and topical anti-inflammatory drugs.

Associated Pathologies

  • Tear duct obstruction
  • Watery eyes
