Tear Duct Surgery or Dacryocystorhinostomy (DCR) is a process conducted (in Iran in a number of eye care centers) to restore communication between the tear ducts and the nasal cavity. There are two openings on our eyelids that lead the old tears to our nasal cavity. Sometimes the tear ducts are blocked due to some environmental issues such as a strong wind or blow and sometimes for no apparent reason. Consequently, the tear drainage system would malfunction. That is to say that the tears can no longer evacuate spontaneously and therefore the patient presents constant tearing with superinfection.

The blockage of tear ducts cannot be solved with medication and a tear duct surgery is required.

 

Blocked Tear Duct Symptoms

The first distress that occurs is inflammation, which causes a partial obstruction of the passage of tears in the wind or cold weather. If the problem persists, the amount of accumulated tears gradually increases and may fall heavily on the cheeks. Normally there would be excessive tearing, followed by pink-eye condition (conjunctivitis) which later can lead to blurred vision.

Sometimes severe conjunctivitis( pink eye), may appear suddenly. This condition can be an obstruction of the canaliculi ( small canals in the eyelids responsible for the liquid drainage) and should be treated straightaway to avoid infection in the nasal cavaties.

 

Tear Duct Surgery is Vital for Your Eye Care

Tear duct surgery is vital for your eye care because:

  • It avoids and prevents infection of the tear ducts, which is potentially dangerous for the eye or face.

  • It obtains re-permeabilization of the tear ducts to avoid further symptoms

 

Endoscopic Endonasal Tear Duct Surgery
It has been some years that endoscopic endonasal surgery has been practiced globally with the highest success rates in this field. The endonasal route, compared to the classic external route, allows:

  • Maintain the integrity of the internal angle of the eye (the openings)

  • Leaving no scar as it is applied via an invasive technique

  • An extremely satisfactory success rate.

 

Conducting an endoscopic dacryocystorhinostomy requires an unprecedented collaboration between the ophthalmologist, the ENT doctor, and the patient. 

 

The surgery is performed under general anesthesia, lasts on average half an hour, and there would be a short overnight hospital stay.




FAQ

Use of ice packs
The silicone tube is removed through the nose 4 to 6 months after surgery without the need for anesthesia or anesthesia.


Although most surgeries are performed under general anesthesia, they can also be performed under local anesthesia, depending on the patient or surgeon.
