Abstract:

Objective  To observe the intraoperative techniques of interventionalprocedure using an artificial nasolacrimal duct and evaluate the effectiveness.Methods  32 cases (32 eyes) of nasolacrimal duct obstruction underwent artificial nasolacrimal duct. The nasolacrimal duct was dilated and the stent was  retrogradely placed.  Dacryocystography was performed before the operation. Results  Artificial nasolacrimal duct placement was technically successful in 30 eyes and the technical success rate was 93.8%(30/32). The response  rate was 100%(30/30)  sixmonths after operation.  Conclusion  Interventional artificial nasolacrimalduct placement is a safe， simple and effective method for the treatment of nasolacrimal duct obstruction．
