方法：选择2015-06/2016-06我院75例93眼泪道阻塞患者随机分为治疗组40例50眼置入新型RS泪道引流管，对照组35例43眼行环形硅胶管置入术，观察两组疗效。

结果：拔管后随访3～12mo，治疗组治愈率及总有效率分别为90%、96%，对照组的治愈率及总有效率分别为72%、84%，差异具有统计学意义(P<0.05)。两组术中术后并发症总发生率分别为治疗组8%、对照组35%，差异具有统计学意义(P<0.05)。

结论：新型RS泪道引流管治疗泪道阻塞手术时间短、操作简便、易拔管、并发症少、安全性高、效果好。

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.

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(P<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(P<0.05).

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.
