目的:回顾研究10a来KTP激光泪道成形术治疗各种泪道阻塞的临床效果。方法:采用KTP激光泪道治疗机,患眼局部常规消毒后,充分扩张泪小点,用带针芯的泪道探针由泪小点插至泪道阻塞处,拔出针芯,将KTP激光导光纤维插至泪道阻塞处,激发激光至泪道阻塞处疏通,并同时接冲左氧氟沙星液,术后隔日泪道冲洗。结果:采用此方法治疗各种泪道阻塞766例870眼,9眼未疏通,疏通率为99.0%。42例溢泪症状再现,泪道冲洗不通畅术后6mo后再阻塞,复打激光者42例42眼,复打率为4.8%;其中36例36眼再次激光无效。825眼一次性疏通,术后泪道冲洗通畅,溢泪症状消失或明显减轻,治愈率为94.8%。结论:KTP激光泪道成形术是目前治疗泪道阻塞损伤性小、治愈率高、效果快捷的治疗方法。

·AIM:To observe the clinical effect of dacryagogic plastic operation by KTP laser in the past ten years.·METHODS:The eyes of patients were routinely disinfected,and the lacrimal puncta were dilated.Then the dacryagogic probe with core was used to locate dacryagogatresia.The probe was removed.The transmitting light fiber of KTP laser was inserted into the position of dacryagogatresia.Laser was emitted until dacryagogatresia was open and washout of the lacrimal passages with levofloxacin was performed every other day.·RESULTS:This method was used to treat various dacryagogatresia in 766 cases,870 eyes.There was no effect in 9 cases.The cure rate was 99.0%.42 cases were treated again,and the rate was 4.8%.825 eyes were opened only once,and the rate was 94.8%.36 cases 36 eyes had no effect after the second treatment.·CONCLUSION:The dacryagogic plastic operation by KTP laser is an effective method with high curative effect for treating dacryagogatresia.·
