Jones pipes

What are jones tubes?

Jones tubes are artificial drainage tubes that replace the lacrimal duct. They are implanted by surgery and will serve to communicate the ocular surface with the nostril.

In which cases is it done?

It is a second choice treatment, since it is performed in lacrimal duct obstruction that cannot be resolved with a dacryocystorhinostomy.

Previous exams

Before applying the jones tubes, a complete ophthalmologic examination should be performed, including an examination of the eyelid and periocular area.

On the other hand, the surgeon must study the irrigation of the lacrimal duct by using a saline solution, which is injected under pressure into the lacrimal duct in order to assess in which area the obstruction is located.

Sometimes it is necessary to perform a dacryoscinography, a functional test of the lacrimal ducts.

During the intervention

The surgeon creates an artificial channel in the nasal bone that communicates the surface of the eye with the nostril, where the jones tube will be placed and fixed. Surgery is performed on an outpatient basis under local anaesthesia and sedation.


The first 24 postoperative hours, the patient must keep the eye occluded. After this time it is recommended that the patient come to the consultation for a review.

In addition, the patient must follow an oral and topical antibiotic and anti-inflammatory treatment.

After two weeks, the patient is visited again to evaluate and control the proper healing and functionality of the jones tube. The final results can be seen a month and a half after surgery.
