眼内レンズ光学系の鑷子痕に感染が疑われて眼内レンズ交換に至った2例

Two cases needing replacement of intraocular lens after detection of signs of infection at the forceps-grasped sites on the lens surface

要約　目的：眼内レンズ（IOL）光学系の鑷子痕に感染が疑われ，IOLの交換をした2例の報告。症例：症例は70歳と61歳の女性で，ともに白内障手術後6日目にIOL前面に鑷子痕に一致して白色沈着物が出現，前房炎症の悪化がみられた。抗菌薬，ステロイドの頻回点眼を行ったが悪化したため，その翌日IOLを摘出，交換した。房水および摘出IOLからは菌は検出されなかった。術後，再発なく，視力は改善した。結論：術後感染が疑われたIOLへの白色付着物に対し，IOLを交換することで，良好な視力予後を得ることができた。

Abstract.　Purpose：To report 2 cases who needed replacement of intraocular lens（IOL）after detection of signs of infection at the sites grasped by forceps on the lens surface. Cases and Findings：Both were females aged 61 and 70 years respectively. They showed precipitates at the sites of IOL grasped by forceps 6 days after cataract surgery. Signs of endophthalmitis were also present that failed to respond to topical antibiotics and corticosteroids. IOL was replaced the following day in both cases. Cultures from aqueous and removed IOL were negative. Both cases have been doing well until present. Conclusion：These cases illustrate that replacement of IOL may be effective after detection of precipitates suggestive of infection.
