采用ＷＺＣ－Ｉ型泪道治疗仪，对６２例（７９只眼）各种泪道阻塞患者进行内高频电灼术，随访观察６～２８个月，治愈结果泪小管阻塞１３只眼（６８．４％），泪总管阻塞１１只眼（７３．３％），鼻泪管阻塞３１只眼（８６．１％），泪小管合并鼻泪管阻塞２只眼（４０％），吻合口阻塞４只眼（１００％）。内高频电灼术对治疗泪道阻塞有疗效确切、操作简单、术后并发症少、不留皮肤瘢痕、可重复治疗及费用低等优点，治疗后不改变或破坏泪道的生理解剖结构，不影响泪泵的导泪功能，具有临床使用价值
Using WZC-I lacrimal treatment instrument, 62 cases (79 eyes) of various lacrimal duct obstruction patients underwent high-frequency electrocautery, followed up for 6 to 28 months, the results of the treatment of lacrimal duct obstruction in 13 eyes (68 .4%), 11 eyes (73.3%) of the common tear tube, 31 eyes (86.1%) of the nasolacrimal duct obstruction, 2 eyes (40%) of the lacrimal duct with nasolacrimal duct obstruction, and anastomotic obstruction 4 eyes (100%). Intra-high-frequency cautery for the treatment of lacrimal duct obstruction has the exact effect, simple operation, less postoperative complications, leaving no skin scars, repeatable treatment and low cost, after treatment does not change or destroy the physiological anatomy of the lacrimal duct , Does not affect the tear guide tear function, with clinical value
