硝子体手術におけるシリコン眼内レンズ挿入眼の問題点

Problems of the presence of silicone intraocular lens during vitreous surgery

　27か月前に，白内障に対してシリコン眼内レンズ挿入術を受けた眼の非裂孔原性網膜剥離に対して硝子体手術を行った。従来のPMMA眼内レンズ挿入眼とは異なる視認性の問題が生じた。一つは眼底周辺部が見にくいことであり，一つは後嚢切開が行われていたために，液空気置換時に眼内レンズの後面に結露が生じ，眼底の視認性が著しく不良なことであった。

We performed vitreous surgery for nonrhegmatogenous retinal detachment in an eye that had undergone implantation of silicone intraocular lens and laser posterior capsulotomy 27 months before. We encountered problems in the visibility of the fundus as different in eyes with PMMA intraocular lens. One was poor visibility of the peripheral fundus during vitreous surgery. The other was moisture condensation on the posterior surface of the intraocular lens during fluid-air exchang.
