二期后房型人工晶体植入术

本文报道对16只(16例)后囊膜完整的无晶体眼进行后房型人工晶体二期植入术的结果.术前的平均未矫正视力为0.06,术后半年,平均未矫正视力为0.53未矫正视力≥0.5的达62.50%,矫正视力≥0.5的占93.37%,≥1.0的占81.25%.术前角膜中央内皮细胞密度平均2646个/mm~2,术后半年为1824个/mm~2,除一例外,其余可恢复立体视.无一例发生持续性角膜水肿和葡萄膜炎等严重并发症.结果表明,只要掌握适应症和手术技术,在后囊膜完整的无晶体眼作二期后房型人工晶体植入是安全有效的方法.本文对手术的适应症、手术方式和技术进行了探讨.

Secondary posterior chamber intraocular lens implantation]

In 16 aphakic eyes (16 patients) with intact posterior capsule posterior chamber IOL implantation were performed. The average uncorrected vision prior to the operation was 0.06. Six months after the implantation the uncorrected vision of > or = 0.5 accounted for 62.5% with an average of 0.53, the corrected vision of > or = 0.5 accounted for 93.37% and that of > or = 1.0 accounted for 81.25%. The average preoperative density of corneal endothelium in the central area was 2,646/mm2, the average of density after the secondary implantation was 1,824/mm2. All but one patient achieved binocular vision postoperatively. No persistent corneal edema and uveitis were found. The results showed that secondary P. C IOL implantation in an aphakic eye with intact posterior capsule is effective and safe if the indications and techniques are well managed.
