To examine the causes signs, and symptoms of anterior capsule contraction syndrome and the response to neodymium YAG (Nd:YAG) anterior capsulotomy.
Madigan Army Medical Center, Tacoma, Washington, USA.
This retrospective review comprised 70 cases of phacoemulsification with foldable plate-haptic silicone intraocular lens (IOL) implantation. Patients who developed anterior capsule contraction postoperatively, defined as the anterior capsule being visible through an undilated pupil, had a radial anterior capsulotomy with an Nd:YAG laser. Variables analyzed were visual acuity, subjective complaints, associated inflammation, and IOL decentration.
Ten eyes of 9 patients (14%) developed anterior capsule contraction and had Nd:YAG laser radial anterior capsulotomy. Three of 9 patients reported decreased visual acuity and glare. Two other patients had chronic anterior chamber inflammation unresponsive to steroids after surgery that resolved after Nd:YAG anterior capsulotomy. Intraocular lens decentration was observed in 3 patients before the Nd:YAG capsulotomy. Posterior lens dislocation occurred in 1 patient after capsulotomy and required surgical lens exchange.
One-piece foldable silicone IOLs may not provide enough peripheral capsule expansion.
探讨前囊膜收缩综合征的病因、体征和症状，以及对钕钇铝石榴石（Nd:YAG）前囊膜切开术的反应。
美国华盛顿州塔科马市马迪根陆军医疗中心。
本回顾性研究纳入70例行折叠式平板襻硅胶人工晶状体（IOL）植入的白内障超声乳化术病例。术后出现前囊膜收缩（定义为在未散瞳的瞳孔下可见前囊膜）的患者接受Nd:YAG激光放射状前囊膜切开术。分析的变量包括视力、主观症状、相关炎症和人工晶状体偏心。
9例患者的10只眼（14%）出现前囊膜收缩并接受了Nd:YAG激光放射状前囊膜切开术。9例患者中有3例报告视力下降和眩光。另外2例患者术后出现对类固醇无反应的慢性前房炎症，Nd:YAG前囊膜切开术后炎症消退。3例患者在Nd:YAG囊膜切开术前观察到人工晶状体偏心。1例患者在囊膜切开术后发生晶状体后脱位，需要手术更换晶状体。
一体式折叠硅胶人工晶状体可能无法提供足够的周边囊膜扩张。
