目的:观察KTP激光联合新型泪道引流管治疗各种原因所致的泪道阻塞。方法:用带针芯的泪道探针探察泪道阻塞处,拨出针芯,再插入KTP激光纤维,发射激光,消除阻塞,疏通泪道,冲洗通畅,用泪道引流管两端分别自上下泪点进入,疏通泪道至鼻腔,两端稍拉紧至鼻孔,至此处打死结,减除多余软管,管结弹回鼻腔。术后点抗生素眼液,3mo后取管。结果:各种原因所致泪道阻塞426例482眼,手术成功445眼(92.3%),失败37眼(7.7%)。结论:KTP激光联合泪道引流管治疗泪道阻塞,操作简便,适应证广,组织损伤小,术后无瘢痕,患者无痛苦,门诊即可手术,时间在5min左右即可完成。

AIM:To investigate the therapeutic effect of KTP laser combined with new lacrimal drainage device for the treatment of lacrimal duct obstruction.METHODS:Lacrimal probe with needle core was penetrated into the lacrimal passage,and the KTP laser fibre was put into the passage to remove the obstruction.Unobstruction of lacrimal passage was confirmed by irrigation.Then,two ends of the lacrimal drainage tube were put into the nose through upper and lower puncta and reopened lacrimal duct.An permanent tie was made with the two ends of lacrimal drainage tube and excess tube was removed.Antibiotic eye drops was applied after the operation.The tube was removed 3 months later.RESULTS:Totally 426 cases (482 eyes) of lacrimal duct obstruction were treated in this way.445 eyes were cured successfully and 37 eyes failed,which accounted for 92.3% and 7.7% respectively.CONCLUSION:KTP laser combined with lacrimal drainage tube is a very simple way to treat lacrimal duct obstruction with the advantages of wide application,minimal tissue damage and no scar.Moreover,it is an outpatient surgery without pain,which takes only 5minutes.
