目的 :探讨 Nd:YAG激光治疗后发性白内障的疗效。方法 :应用 Nd:YAG激光分别对 6 9例白内障超声乳化人工晶体植入术后发障进行后囊膜切开。结果 :6 9病例中 ,后囊膜混浊者共 45例 (6 5 .2 % ) ,后囊膜皱褶者共 12例 (17.4% ) ,既有后囊膜混浊又有后囊膜皱褶者共 12例(17.4% ) ;Nd:YAG激光后囊膜切开术前后视力有显著性差异 (P〈0 .0 0 5 ) ,6 9例中有 6 0例经过 Nd:YAG激光后囊膜切开术后视力达到了白内障超声乳化术后的最佳视力 ;但仍有 9例未达到该最佳视力。结论 :“囊袋收缩综合征”影响 Nd:YAG激光后囊膜切开术的治疗效果 ,白内障手术方法和人工晶体的选择可降低后发障的发生。
Objective: To investigate the effect of Nd: YAG laser in the treatment of post-cataract. Methods: Nd: YAG laser was used to perform posterior capsulotomy in 69 cases of phacoemulsification cataract extraction. Results: In 69 cases, there were 45 cases (65.2%) with posterior capsular opacities and 12 cases (17.4%) with posterior capsular folds. Both posterior capsular opacification and posterior capsular folds There were 12 cases (17.4%) of them had visual acuity before and after Nd: YAG laser capsulotomy (P <0.05), 60 cases of 69 cases had Nd: YAG laser After capsulotomy visual acuity reached the best visual acuity after cataract phacoemulsification; but still 9 cases did not reach the best visual acuity. CONCLUSIONS: “Systolic capsular syndrome” affects the therapeutic effect of posterior capsulotomy with Nd: YAG laser. The cataract surgery and the selection of intraocular lens may reduce the incidence of posterior capsulotomy.
