目的：分析Nd：YAG激光治疗泪道阻塞的临床疗效以及对不同阻塞部位的有效率的分析。
方法：对2009-02/2011-12我院门诊840例920眼不伴有泪囊炎的泪道阻塞患者，均采用Nd：YAG脉冲激光机治疗，其中泪小管阻塞134眼，鼻泪管阻塞786例眼，术后行连续4d妥布霉素地塞米松或复方硫酸新霉素滴眼液泪道冲洗。分别对单纯泪小管和鼻泪管阻塞患者进行3mo随访。
结果：总有效率76.2%，其中泪小管阻塞有效94眼，有效率70.1%。鼻泪管阻塞有效607眼，有效率77.2%，单纯鼻泪管阻塞患者的有效率高于单纯泪小管阻塞患者。
结论：Nd：YAG激光治疗单纯泪道阻塞(不伴泪囊炎)具有理想的疗效，方法简单易行，有效率高，患者痛苦小，并发症少，花费少，无效患者后续可选替代治疗方案多，可以作为单纯泪道阻塞疾病的首选方案。激光泪道成形术对单纯鼻泪管阻塞患者的有效率略高于单纯泪小管阻塞。

[Abstract]
AIM: To evaluate the therapeutic efficacy of Nd:YAG laser on lacrimal duct obstruction and the different efficiency of obstruction on different location.
METHODS: Totally 920 eyes(840 patients)with no dacryocystitis received Nd:YAG laser treatment, including 134 eyes with lacrimal canaliculus obstruction and 786 eyes with naso-lacrimal duct obstruction. Every case received 4 days' lacimal duct wash by Poly Pred or Tobradex. Patients in two groups were followed up for 3 months.
RESULTS:Total efficiency was 76.2%. Efficiency of naso-lacrimal duct obstruction group was 77.2%(607 eyes), which was obviously higher than 70.1%(94 eyes)in lacrimal canaliculus obstruction by one point group.
CONCLUSION:Nd:YAG laser can be suggestively applied in treatment on lacrimal duct obstruction, especially can be used in naso-lacrimal duct obstruction due to its simplicity, economy, practicability, less side effect and complication.
