I. What is lacrimal duct disease.
Lacrimal tract disease is a common and frequent disease in ophthalmology, mainly including upper and lower lacrimal duct obstruction, common lacrimal duct obstruction, nasolacrimal duct obstruction and chronic dacryocystitis. Patients have symptoms such as unconscious tearing and pus flow, as well as potential infection factors, which can easily cause corneal ulceration and affect the implementation of internal eye surgery.

Second, traditional treatment methods
The traditional surgical treatment methods are: ① lacrimal duct placement silicone tube, ② lacrimal duct laser shaping, ③ lacrimal duct exploration, ④ external incision lacrimal sac nasal anastomosis, ⑤ nasal endoscopic lacrimal sac nasal anastomosis. The first three methods have a high recurrence rate of tearing. The last two methods have a high success rate of surgery, but the surgery is complicated and the tissue damage is large. Especially the fourth method leaves scars on the facial skin, and there are relatively more complications and contraindications for the surgery.
Nasolacrimal Duct Intervention
Nasolacrimal duct intervention is a minimally invasive treatment method that uses imported cardiovascular treatment materials that are placed into the nasolacrimal duct and tear sac and retained for three months, or for life.
Advantages of nasolacrimal duct interventional therapy.
1, high success rate of the procedure.
2, simple, safe and time-saving operation.
3, less bleeding, less pain, all patients can tolerate.
4, does not change the original anatomical position, artificial nasolacrimal duct obstruction, can be re-intervention or change to other methods.
5, no skin incision, no scar on the face after surgery.
6.The surgical indications are wide and the efficacy is sure.
Indications for surgical treatment.
Chronic dacryocystitis, nasolacrimal duct obstruction, nasolacrimal duct stenosis, lacrimal sac mucus cyst, nasolacrimal sac anastomosis reobstruction.
Contraindications to surgical treatment.
Acute dacryocystitis, bony nasolacrimal tract abnormalities, bleeding tendency nasopharyngeal tumors.
Postoperative care.
Rinse the tear duct once a day for 1 week after surgery and use eye drops and other medications as prescribed by the doctor.
