AIM: To study the clinical effects of treatment of nasolacrimal duct obstruction with KTP lacrimal laser combined with intubation of disposable lacrimal duct recanalization tube.

METHODS: Laser surgery lacrimal duct obstruction was performed first, then the guide line was penetrated, nasolacrimal duct expanded with expansion silicone in package, and then disposable lacrimal duct recanalization tube was implanted.

RESULTS: All 30 patients 30 eyes were followed up for 6-24 months, 1 eye obstructed again, the effective rate was 97%.

CONCLUSION: KTP laser and lacrimal duct recanalization tube intubation for treatment of serious nasolacrimal duct obstruction can significantly improve the success rate and the effective rate.
