Abstract

A 65-year-old male presented with decreased vision (20/200) from the past nine months after having undergone cataract surgery (phacoemulsification) four years ago. Anterior segment examination revealed diffusely opacified intraocular lens, and he was diagnosed as a case of delayed intraocular lens (IOL) opacification. IOL lens exchange surgery was planned. A per-operative assessment revealed significant fibrosis of IOL with the capsule. Viscoelastic was used for viscodissection, and the IOL was mobilized and removed. Capsular integrity was ensured and achieved, and a new foldable IOL was implanted in the bag. Best-corrected visual acuity (BCVA) after the surgery improved to 20/20. Here, we discuss different IOL exchange techniques and report our successful viscodissection despite significant fibrosis and the time interval of four years since the initial implant.

摘要

一名65岁男性，四年前接受白内障手术（超声乳化）后，在过去九个月中视力下降至20/200。前段检查发现人工晶状体弥漫性混浊，他被诊断为迟发性人工晶状体（IOL）混浊。计划进行IOL晶状体置换手术。术中评估显示IOL与囊膜有明显纤维化。使用粘弹剂进行粘弹分离，将IOL松动并取出。确保并实现了囊膜完整性，在囊袋内植入了一枚新的可折叠IOL。术后最佳矫正视力（BCVA）提高到了20/20。在此，我们讨论不同的IOL置换技术，并报告尽管存在明显纤维化且距初次植入已有四年时间间隔，但我们成功进行粘弹分离的情况。
