眼内レンズ挿入術による緑内障予後

Course of glaucoma following intraocular lens implantation

　過去8年間に白内障手術と眼内レンズ（IOL）挿入術を行った緑内障88眼72症例を検索した。年齢は平均69.5±13.8歳であり，1年以上の経過を観察した。白内障術式，IOLの種類，IOLの固定状態は，いずれも術後の視力，眼圧，視野，一過性高眼圧と有意差はなかった。術中に破嚢した5眼と破嚢しなかった83眼との間に，術後の視力，眼圧，視野について有意差はなかった。術後の一過性高眼圧は，破衝群3眼（60％），非破嚢群10眼（12％）に生じ，有意差があった（p＝0.003）。この差には，破嚢眼での粘弾性物質の残留と術後の炎症が関係していると推定された。

We reviewed 88 glaucoma eyes of 72 patients following cataract surgery with intraocular lens (IOL) implantation during the past 8 years. Their ages averaged 69.5 ± 13.8 years. All the cases were followed up for one year or longer. Neither the method of cataract surgery, type of IOL, nor the state of IOL fixation was related with the visual acuity, intraocular pressure (IOP), or temporary IOP rise after surgery. There was no difference in the course of visual acuity, IOP or visual field between 5 eyes which developed capsular rupture and 83 eyes which did not. The incidence of temporary postoperative KW rise was 3 eyes (60%) with capsular rupture and 10 eyes (12%) without. The difference was significant (p = 0.003) . It appeared that this difference was due to inflammation and residual viscoelastic material in eyes with capsular rupture.
