方法：上泪道阻塞患者128例148眼，全部有流泪病史，均经泪道冲洗检查确诊，行激光泪道成形联合硅胶管植入术，保留硅胶管1a，拔管后随访24mo，定期冲洗泪道，观察泪道通畅情况。

结果：拔管后治愈120眼(81.08%)，无流泪，泪道保持通畅； 好转18眼(12.16%)，流泪减轻，泪道通而不畅； 无效10眼(6.76%)，仍流泪，泪道冲洗不通。总有效率达93.24%。

结论：激光泪道成形联合硅胶管植入术是治疗上泪道阻塞的有效方法。

METHODS:There were 128 cases(148 eyes)with canalicular obstruction, all of them had a history of the tears, and were diagnosed by flushed lacrimal duct, and they underwent laser lacrimal plastic operation combined with silicone tube implantation, the silicone tube was kept in place for one year, after operation, the patients flushed lacrimal duct regularly and they were followed up for 24 months after extraction of the silicone tube, the recovery of function of lacrimal duct was observed.

RESULTS:Twenty-four months after extraction of the silicone tube,120 cases(81.08%)were cured, had no tears and with the complete unobstruction, 18 cases(12.16%)were improved, still had tears and lacrimal passage is passable. 10 cases(6.76%)were invalid, still had tears and with the obstruction, the total efficiency rate was 93.24%.

CONCLUSION: It is an effective method of laser lacrimal plastic operation combined with silicone tube implantation in canalicular obstruction.
