What does it involve?
This is a surgical procedure that involves replacing the tear duct with an artificial drainage tube. This creates a channel between the surface of the eye and the nasal cavity through which tears can drain.
When it is carried out?
In patients with tear duct obstruction that cannot be fixed with dacryocystorhinostomy.
- 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 is necessary, i.e. a test to check tear duct function.
During the Operation
- The procedure is performed under local anaesthesia and sedation on an outpatient basis.
- The surgeon creates a channel between the surface of the eye and the nasal cavity through a small hole in the nasal bone, which holds the Jones tube in place..
After the Operation
- The patient’s 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.
- The surgeon examines the patient again after two weeks to assess and monitor the healing process and check that the Jones tube is working correctly.
- The final results are noticeable within a month and a half of surgery.
