Dacryocystorhinostomy(DCR) is a surgery to restore tear drain by removing lacrimal duct obstruction through creating a hole in bone that connects the lacrimal sac and the nasal cavity.
Overview of Dacryocystorhinostomy
If you look carefully at the inner corner of the eye, you will see the tear duct on the edge of each of the lower and upper eyelids which is a duct for the entrance of the tear to its drainage system. The duct connects this pore to the lacrimal sac which is located below the inner corner of the eye. The tear in the lacrimal sac drains to the nose via the nasolacrimal duct. If the lacrimal duct obstructs, the tear will drain from the surface of the eye. The solution to this problem is to do a surgery called Dacryocystorhinostomy. Treatment is performed under the supervision of an expert surgeon in the lacrimal duct surgeries (plastic eye surgeon).

• patients who have Dacryocystitis
Before Dacryocystorhinostomy (DCR)
The doctor will do examinations to find out whether these watery eyes are the result of increased tear production or reduction of the drain. Along with physical examination, the ophthalmologist may ask for some images, and after confirmation of the lacrimal duct obstruction, the dacryocystorhinostomy will be planned. Patients should keep in mind to tell the surgeon their medical history, allergies and supplements and medicines they are taking.
During Dacryocystorhinostomy (DCR)
The surgeon performs this procedure under local or general anesthesia depending on the eye condition. In endoscopic dacryocystorhinostomy (DCR) an endoscope with a camera enters the lacrimal sac from the nostrils. Then a small piece of bone between the lacrimal sac and the nose is removed, and the possibility of direct tear discharge from the lacrimal sac into the nose is provided. Usually, during the procedure, a silicone tube is also placed temporarily in the duct to prevent the obstruction of the duct after surgery. This tube has no pain and does not cause any problems.
After Dacryocystorhinostomy (DCR)
In some patients, eyes are dressed, and a nose tampon is inserted for 24 or 48 hours after the surgery. It is recommended to place cold compresses to the nose until 24 hours after surgery, to prevent the nose bleeding. As long as the silicone tube is located in the duct, a little tearing is probable that will be solved after removing the tube. The surgeon may prescribe some antibiotics and ophthalmic and nasal drops; patients should take them carefully as he or she said. Patients should avoid bending down their head, eating and drinking hot foods and liquids up to a week after the surgery, because failure to observe the above may result in severe pain or bleeding.
