2key factors: excellent drainage and extended durability
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 is it 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.
