人工後房レンズ移植術の合併症とその対策

Complications of posterior chamber intraocular lens implantation

　人工後房レンズ移植術を施行した1,000眼の合併症について検討し以下の結論を得た．

（1）術後矯正視力0.5以上を得たものは95.5％であった．

（2）合併症は1,000眼中177眼17.7％にみられ，その85.9％が術後3カ月未満に発症した．

（3）合併症のうち再手術が必要であった症例は12.4％であった．

（4）術中後嚢損傷により前房レンズに変更した症例の術後視力および角膜内皮細胞の変化は，後房レンズ移植眼とほぼ同様の結果であった．

We evaluated the results of posterior chamber lens (PCL) implantation in a consecutive series of 1,000 eyes with particular attention to postsurgical complications.

A total of 95.5% of operated eyes attained pos-toperative visual acuity of 20/40 or more.

Postoperative complications developed in 177 eyes (18%). The complications became manifest within 3 months after surgery in 86% of the cases.The complications had to be surgically treated in 12.4% of the invovled eyes.

There were 42 eyes besides the present series in which anterior chamber lens (ACL) had to be inser-ted due to unintended rupture of the posterior cap-sule dueing KPE procedure. There was no differ-ence between the PCL and ACL groups as regards the postoperative visual acuity and changes in cor-neal endothelial cells.
