In the last six months, I have done about 200 cases of tear duct probing in my outpatient clinic, and I have recorded the patients’ situation with my heart, and I have the following experience for the reference of patients and peers. The recurrence rate of tear duct probing is actually very low, generally common in patients with high obstruction, multiple adhesions, or postoperative nasal congestion and runny nose, and the age and size of the rinsing with or without pus has no obvious relationship. In addition, many children have severe eczema on the same side of the eyelid and face due to long-term tear duct obstruction, and I recommend early exploratory surgery for these patients, rather than waiting until six months. Postoperatively, we recommend rinsing a week later and trying not to catch a cold, especially if you have nasal symptoms. It is also recommended to order eye drops for one week before surgery to control inflammation and to avoid recurrence of adhesions caused by too much inflammation after surgery.
