Abstract: Objective To explore the impact of lacrimal duct laser combined with drainage tube implantation on the ocular surface of patients with lacrimal duct obstruction. Methods Between January 2014 and December 2015, we treated 120 cases of lacrimal duct obstruction. A digital parity method randomly divided these individuals into a control group(60 individuals)and an observation group(60 individuals). The control group received conventional surgical treatment. The trial group received laser treatment combined with lacrimal drainage tube implantation. The data from the trial group were retrospectively analyzed. The percentage of cases in which treatment was effective was analyzed. Tear film break-up time(following extubation)and tear secretions were also analyzed. Results In the control group, treatment was effective in 75.0% of cases. This percentage was significantly lower than that in the trial group, where treatment was effective in 91.7% of cases(P<0.05). The tear film break-up time did not significantly differ between groups. Tear secretions following extubation were not significantly different between groups. In the trial group, tear secretion was significantly increased at one month after treatment compared to before treatment(P<0.05). Conclusion The use of laser treatment combined with a lacrimal drainage tube implantation was found to be a better therapeutic option than the conventional treatment for lacrimal duct obstruction. Laser combination therapy had no effect on the state of the ocular surface.
