目的:探讨激光泪道再通术联合泪道置管术治疗泪小管阻塞性疾病的临床疗效。方法:泪小管阻塞性疾病患者45例45只眼,常规行泪道冲洗及探查,全部明确为泪小管阻塞。经激光泪小管成形后,分别自上下泪小管植入硅胶导管,拉紧打结与鼻腔。冲洗结膜囊,抗菌素眼液点眼。结果:全部手术均一次顺利完成。术后3个月,均顺利拔管。泪道冲洗通畅。流泪症状消失。结论:泪小管阻塞激光再 Objective: To investigate the clinical effect of laser lacrimal passage recanalization combined with lacrimal duct placement in the treatment of obstruction of lacrimal duct obstruction. Methods: 45 patients with 45 cases of lacrimal duct obstructive disease, routine lacrimal irrigation and exploration, all clear for the canalicular obstruction. After laser lacrimal duct formation, respectively, from the upper and lower canaliculus implantation of silicone catheters, tighten knot and nasal cavity. Flush conjunctival sac, eye drops of antibiotic eye drops. Results: All the operations were completed successfully. 3 months after operation, both extubation. Lacrimal duct wash patency. Tears symptoms disappear. Conclusion: lacrimal duct obstruction laser again
