AIM: To observe the effect of laser combined with lacrimal duct intubation on the treatment of lacrimal duct obstruction diseases.

METHODS:Of 79 patients(96 eyes)with lacrimal duct obstruction diseases, 27 eyes(22 eyes with canaliculi lacrimalis or lacrimal duct shutting and 5 eyes with ductus nasolacrimalis)underwent laser combined lacrimal drainage tube implantation, 69 eyes(27 eyes with ductus nasolacrimalis and 42 eyes with chronic dacryocystitis)received laser combined with nasolacrimal duct stenting. Eye drops included dexamethasone and antibiotic medicine were given in a week after operation. The patients implanted lacrimal drainage tube removed the tube at 3-6 month after operation, the other removed nasolacrimal stenting at 4 weeks after operation, all of patients were followed-up 12 months.

RESULTS:Seventy-nine eyes were cured in all of the 96 eyes, 10 eyes were better, 7 eyes were ineffective. All 96 eyes had not been seen pus after being rinsed. Total efficiency was 93% and significant efficiency was 82%.

CONCLUSION: Laser combined with different silicone tube implantation according to the different site was a simple and effective way inthe treatment of lacrimal duct obstruction.
