目的观察KTP激光治疗泪道阻塞的效果.方法用特制空心泪道探针探查泪道至阻塞处,插入KTP激光导光纤维,发射激光,疏通泪道.术后根据阻塞程度及有无分泌物予以不同药物灌注及短期留置泪道支撑物.结果对696例827眼随访观察805眼,观察时间为1周至6个月,经1次激光治疗,治愈562眼,好转208眼,无效35眼.2次以上激光治疗,治愈191眼,好转44眼,无效8眼.总治愈率93.5%,好转率5.5%,无效1%.结论KTP激光治疗泪道阻塞安全、有效.术后联合药膏灌注泪道,短期留置支撑物等处理有利于巩固疗效.

KTP-Nd:YAG laser-assisted dacryocystoplasty for lacrimal duct obstruction

Objective To evaluate the therapeutic efficacy of KTP Nd: YAG laser assisted dacryocystoplasty for lacrimal duct obstruction. Methods Specially made hollow lacrimal probe was used to examine the lacrimal ducts to the obstructed parts in a total of 827 eyes. Then KTP laser fibers were inserted into the lacrimal ducts to dredge the obstructed parts by laser. Instillation of different drugs or short term placement of lacrimal supporters was conducted after operation according to the symptoms such as degree of obstruction and with discharges or not. Results The cure rate, improvement rate, and ineffectiveness rate were 93.5%, 5.5%, and 1%, respectively. One therapy was conducted in 562 eyes, twice in 191 eyes. Conclusion KTP Nd: YAG laser assisted dacryocystoplasty is a safe and effective way for the treatment of lacrimal obstruction. Postoperative drug instillation or short term placement of lacrimal supporter can contribute to the clinical outcomes.
