2problems: tearing and eye infections
What does it involve?
It is a surgical procedure recommended for patients with tear duct obstruction and consists of forming a new lacrimal duct using the patient's own tissue.
When is it carried out?
- When the tear duct is obstructed below the lacrimal sac.
- 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 tear duct function test.
During the operation
- The procedure is performed under local anaesthesia and sedation on an outpatient basis.
- During surgery, silicone tubes are temporarily inserted into the tear duct. 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.
