Objective:
To investigate the therapeutic effect of a new probe for congenital nasolacrimal duct obstruction.
Methods:
The probe was designed and manufactured by ourselves. We observed 158 cases (172 eyes) with congenital nasolacrimal duct obstruction and treated them with the probe 1-3 times.
Results:
The mean period of postoperative follow-up was 17.8 (range 12-24 months) months. The success rate was 98.2%. Common complications included a slight blood-stained nasal discharge.
Conclusion:
Our newly designed and manufactured probe provides a new probe for congenital nasolacrimal duct obstruction. The probe is a safe, simple and effective treatment method for congenital nasolacrimal duct obstruction.
