To examine the effect of anterior capsule relaxing incisions created with a neodymium:YAG (Nd:YAG) laser on prevention of anterior capsule contraction after cataract surgery in high-risk patients.
Hayashi Eye Hospital, Fukuoka, Japan.
Randomized masked clinical trials.
Patients at high risk for anterior capsule contraction had anterior capsule relaxing incisions in either eye 3 days postoperatively. The anterior capsule opening was measured using a Scheimpflug videophotography system (EAS-1000) immediately and 1, 3, and 6 months after capsulotomy, and the percentage reduction in area was calculated. The degree of intraocular lens (IOL) decentration and tilt, posterior capsule opacification (PCO), and other complications were also assessed.
Of the 84 patients included, 30 had primary angle closure, 28 had pseudoexfoliation, and 26 had diabetic retinopathy. There was no significant difference in the mean opening area between fellow eyes at baseline. In patients with primary angle closure, the area was significantly greater and the percentage reduction in area was significantly less in the capsulotomy group than in the no-capsulotomy group (P≤.0428). In patients with pseudoexfoliation or diabetic retinopathy, the percentage reduction was significantly less in the capsulotomy group than in the no-capsulotomy group (P≤.0493), although there was no significant difference in area. No significant difference was found in IOL decentration or tilt, PCO, or incidence of other complications.
Neodymium:YAG laser anterior capsule relaxing incisions in the early period after cataract surgery were effective in preventing anterior capsule contraction in high-risk patients and had no adverse effects.

研究白内障术后应用钕：钇铝石榴石（Nd：YAG）激光行前囊膜切开对预防高危患者前囊膜收缩的效果。
日本福冈林眼科医院。
随机、双盲临床试验。
高危前囊膜收缩患者术后 3 天于单眼行前囊膜松解切开术。应用 EAS-1000 型 Scheimpflug 视频摄影系统即刻及术后 1、3、6 个月测量前囊膜开口，并计算面积减少百分比。评估人工晶状体（IOL）偏心和倾斜度、后囊膜混浊（PCO）及其他并发症。
84 例患者中，原发性闭角型青光眼 30 例，假性剥脱综合征 28 例，糖尿病性视网膜病变 26 例。术前双眼平均开口面积无显著差异。在原发性闭角型青光眼患者中，与未行切开术组相比，切开术组的面积显著增大，面积减少百分比显著减少（P≤.0428）。在假性剥脱综合征或糖尿病性视网膜病变患者中，切开术组的面积减少百分比显著小于未行切开术组（P≤.0493），但两组间面积无显著差异。IOL 偏心或倾斜度、PCO 或其他并发症发生率无显著差异。
白内障术后早期应用 Nd：YAG 激光行前囊膜松解切开术可有效预防高危患者前囊膜收缩，且无不良反应。
