Comparative study of two kinds of lacrimal drainage tubes for lacrimal duct obstruction / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To observe the clinical effect of the neotype lacrimal drainage tube(RS model)for the treatment of lacrimal duct obstruction.<p>METHODS: It was a retrospective case series study. Totally 75 cases(93 eyes)of lacrimal duct obstruction were enrolled in the study and randomly divided into two groups treatment group(50 eyes)and control group(43 eyes). The treatment group was implanted the neotype lacrimal drainage tube(RS model). The control group underwent the implantation of annular silicone tube and their efficacy were analyzed. <p>RESULTS: Followed up for 3-12mo after extubation, the cure rate and total effective rate of the treatment group were 90%, 96% respectively, and the control group of it were 72%, 84%.The difference between the two groups was statistically significant(<i>P</i><0.05). The total rate of intraoperative and postoperative complications was 8% in treatment group, 35% in control group respectively, the rate of the control group was obviously higher than that of the treatment group, there was significant statistical difference between the two groups(<i>P</i><0.05). <p>CONCLUSION: The implantation of the neotype lacrimal drainage tube(RS model)is safe,fast and simple, easy to operate and extubate easily with good clinical effect in the treatment of lacrimal duct occlusion.
