目的：对泪道环形硅胶支架植入的手术方法和器械进行了改进，使手术过程简单易学，治疗效果良好。
方法：A组：泪道阻塞90眼，用Nd：YAG激光疏通泪道后，采用改良的环形硅胶支架植入术治疗； B组：泪道阻塞80眼，用Nd：YAG激光疏通泪道后，采用经典的环形硅胶支架植入术治疗。术后均随访2a，比较两组的治愈率及有效率。
结果：随访2a，A组治愈80眼，治愈率为89%，好转7眼，好转率为8%，总有效率为97%，无效3眼； B组治愈60眼，治愈率为75%，好转9眼，好转率为11%，总有效率为86%，无效11眼。两组治愈率之间比较，差异有统计学意义(χ2=5.62，P<0.05)； 两组总有效率比较，差异有统计学意义(χ2=4.78，P<0.05)。
结论：改进的硅胶支架植入方法治疗泪道阻塞效果更佳，值得推广。

[Abstract]
AIM: To ameliorate the techniques and instruments forlacrimal duct obstruction in order to learn easily and achieve better surgical effects.
METHODS:Group A: 90 eyes with lacrimal duct obstruction were treated with the ameliorated annular silicone stent intubation; Group B: 80 eyes were treated with the classical annular stent intubation. Follow up in 2 years after operation, comparing the rate of cure and efficiency between the two groups.
RESULTS: After a two-year follow-up, in group A, 80(89%)eyes were cured, 7 eyes(7.8%)turned better and 3 eyes failed to respond, the total effective rate was 97%; in group B, 60(75%)eyes were cured, 9(11%)turned better and 11 failed to respond, the total effective rate was 86%. Differences in cure rate(χ2=5.62, P<0.05)and total effective rate(χ2=4.78, P<0.05)between two groups had statistical significance.
CONCLUSION: The ameliorated means is simple and effective in treatment oflacrimal canaliculi occlusion, it is worth of spreading.
