目的：研究了白内障囊外摘除或联合人工晶体植入术后囊混浊行激光治疗的临床意义。方法：Ｎｄ：ＹＡＧ治疗，行后囊混浊１９４例（１９４只眼）切开术，术后随访１～３２个月，平均为１４．２９±９．１８个月，结果：激光后视力０．５以上者占７１．７％；激光前后眼压变化不明显；本组研究范围内，未发现激光总能量与眼压增加有相关性。结论：Ｎｄ：ＹＡＧ激光是后囊混浊有效、方便、合理的重要治疗方法。
Objective: To study the clinical significance of labyrinthine laser surgery after extracapsular cataract extraction combined with intraocular lens implantation. Methods: 194 cases (194 eyes) underwent posterior capsular opseation were treated with Nd: YAG. The patients were followed up for 1 to 32 months with an average of 14.29 ± 9.18 months. Results: The posterior visual acuity was 0. More than 5 accounted for 71.7%; changes in intraocular pressure before and after laser was not obvious; within the scope of this study, did not find the total laser energy and intraocular pressure increased correlation. Conclusion: Nd: YAG laser posterior capsule opacification is an effective, convenient and reasonable method of treatment.
