掺钕钇铝石榴石激光前囊膜切开治疗早期囊袋阻滞综合征1例

Treatment of early capsular blockage syndrome with Nd:YAG laser anterior capsulotomy containing neodymium-doped yttrium aluminum garnet in a case

62岁女性患者因右眼白内障摘除术后视力无改善10 d就诊。右眼裸眼视力0.1, 裂隙灯显微镜下可见人工晶状体在位, 人工晶状体与后囊膜间距增宽。眼前节相干光层析成像术检查可见晶状体后囊膜与人工晶状体后表面间距为3.236 mm。结合病史、眼部检查及辅助检查诊断为右眼囊袋阻滞综合征。于人工晶状体光学区以外的前囊膜处行掺钕钇铝石榴石激光造孔治疗, 1周后后囊膜与人工晶状体后表面贴附, 视力较前明显提高。

A 62-year-old female patient presented with no improvement in vision 10 days after undergoing cataract extraction in the right eye.The unaided visual acuity in the right eye was 0.1,and examination with a slit lamp revealed the presence of the intraocular lens with an increased gap between the intraocular lens and the posterior capsule.Anterior segment optical coherence tomography showed a distance of 3.236 mm between the posterior capsule and the posterior surface of the intraocular lens.Based on the medical history,ocular examination,and auxiliary examinations,a diagnosis of right eye capsular blockage syndrome was made.Nd:YAG laser capsulotomy was performed at the anterior capsule outside the optical zone of the intraocular lens.One week later,the posterior capsule adhered to the posterior surface of the intraocular lens,and there was a significant improvement in vision compared to before the procedure.
