(C4-2-2) 強度近視眼では通常の白内障眼と比較して前房深度が深く眼軸長が長いため,白内障手術時のハンドピースの挿入時には虹彩や毛様体が上下動し内臓痛を引き起こしやすい。今回,白内障手術に用いられる眼内灌流液オキシグルタチオン溶液にリドカインを注入し,0.2%リドカイン眼内灌流液を用い点眼麻酔に併用したところ,点眼麻酔単独群より有意に強い疼痛抑制効果が得られた。また,角膜内皮細胞減少率は麻酔単独群と比較して有意差はみられなかった。0.2%リドカイン眼内灌流麻酔は強度近視眼白内障手術に有用であった。
We reviewed 14 eyes of 14 patients with high myopic which underwent cataract surgery. The refraction averaged -8.6 diopters. The 14 eyes were randomly divided into two groups comprising 7 eyes each. One group received intracameral irrigation of 0.2% lidocaine in addition to conventional topical anesthesia. This group showed significantly lesser pain than the other group. There was no difference in the reduction of corneal endothelial cells between both groups. The findings show the usefulness of the present procedure for cataract surgery in high myopic eyes.
