目的 通过KTP激光临床应用,观察KTP激光探通术加透明质酸钠置留治疗各种原因所致的泪道阻塞的治疗效果。方法 用带针芯的泪道探针探查泪道至阻塞处,拔出针芯,再插入KTP激光导光纤维,发射激光,清除阻塞,疏通泪道。注入透明质酸钠置留。结果 各种原因泪道阻塞19眼,手术成功18眼,失败1眼。结论 KTP激光探通术加透明质酸钠置留能有效地治疗各种泪道阻塞。 Objective To observe the therapeutic effect of lacrimal passage obstruction caused by various reasons by KTP laser exploration and sodium hyaluronate placement through clinical application of KTP laser. Methods Using lacrimal probe with a needle core to probe the lacrimal passage to the obstruction, pull out the needle core, then insert the KTP laser light guide fiber, launch the laser, clear the obstruction and clear the lacrimal passage. Sodium hyaluronate infusion set aside. The results of various reasons lacrimal duct obstruction in 19 eyes, 18 eyes were successful, failed 1 eye. Conclusion KTP laser exploration combined with sodium hyaluronate retention can effectively treat various lacrimal duct obstruction.
