要約 目的:眼内レンズ(IOL)強膜内固定術において,使用IOL別に固定位置(傾斜・偏心)を含めた臨床経過を比較検討する。
対象と方法:2020年3月〜2023年3月に東北大学病院眼科にて同一術者によりNX-70S(エタニティーファインナチェラル,光学径7.0mm),もしくはPN6AS(アバンシィプリセット,光学径6.0mm)を用いて強膜内固定術を行い,経過を3か月以上観察できた患者45例50眼を対象とした。IOLの傾斜・偏心および目標屈折度と術後1週間程度での屈折度の誤差,術後合併症を後向きに検討した。
結果:50眼の内訳はNX-70S群が11例,PN6AS群が39例であり,術後レンズ傾斜角度はそれぞれ7.73±4.99度,7.99±4.59度(p=0.75),偏心は0.58±0.29mm,0.59±0.33mm(p=0.53)であり,2群間に有意差はなかった。また術後屈折誤差についてもNX-70S群で0.78±0.55D,PN6AS群で0.64±0.52Dであり有意差はなかった(p=0.17)。術後合併症として高眼圧(7/50件:14%),硝子体出血(4/50件:8%),虹彩捕獲があり(2/50:4%)を認め(いずれも2群間に有意差なし),虹彩捕獲1例のみ再手術を要した。
結論:IOL強膜内固定術において,光学径の異なるIOL間でもレンズ傾斜・偏心,また術後の屈折誤差において有意差はなかった。
Abstract Objective:To compare the clinical outcomes of intraocular lens intrascleral fixation, including fixation position(tilt and eccentricity).
Subjects and Methods:Forty-five patients(50 eyes)who underwent intraocular scleral fusion using NX70S(Eternity®, 7.0 mm optical diameter)or PN6AS(Avancy®, 6.0 mm optical diameter)by the same surgeon at Tohoku University Hospital between March 2020 and March 2023 were included in this study. The patients were observed for at least 3 months. Intraocular lens tilt and eccentricity, refractive error between the target refraction and the target refraction at approximately one week postoperatively, and postoperative complications were examined retrospectively.
Results:The 50 eyes comprised 11 eyes with treated with NX70S and 39 PN6AS. There were no significant difference in postoperative lens tilt angles(NX70S 7.73±4.99°and 7.99±4.59°)and eccentricities(NX70S 0.58±0.29 mm)and(PN6AS 0.59±0.33 mm)between the two groups(p=0.75 and p=0.53, respectively). Postoperative refractive error was 0.78±0.55D in the NX70S group and 0.64±0.52D in the PN6AS group, with no significant difference(p=0.17).
Postoperative complications included high intraocular pressure(7/50:14%)and vitreous hemorrhage(4/50:8%), but no reoperation was required.
Conclusions:There were no significant differences in lens tilt, eccentricity, or postoperative refractive error between lenses with different optical diameters treated with intraocular lens scleral fixation.
