多焦点眼内レンズの片眼挿入例と両眼挿入例の比較検討

Comparison of unilaterally and bilaterally implanted multifocal intraocular lens

要約　目的：片眼白内障手術症例に多焦点眼内レンズを挿入し両眼挿入例と比較検討すること。対象と方法：当院で多焦点眼内レンズを挿入された白内障症例17例28眼（男性8例12眼，女性9例16眼）。僚眼健常な片眼症例6例6眼（片眼群）と，両眼症例11例22眼（両眼群）について，患者背景，裸眼遠方，近方視力の改善およびハロー，グレアの有無と程度，満足度について検討した。結果：片眼群は両眼群より若年者が多かった（平均年齢が片眼群48.5±13.9歳，両眼群69.8±9.2歳）。片術後の裸眼遠方，近方視力は全例で向上した。ハロー，グレアは両群とも80％以上みられたが，日常気になると答えた症例はなかった。Waxy visionは両群ともにみられなかった。満足度は，両群とも全員が満足で，不満例はなかった。結論：片眼への多焦点眼内レンズ挿入は両眼挿入と比べ遜色ない患者満足が得られることが示された。

Abstract.　Purpose：To compare the efficacy of multifocal IOL implantation in patients with unilateral cataract and bilateral cataract. Cases：A total of 28 eyes of 17 patients underwent cataract surgery by an identical surgeon. 6 eyes of 6 patients had unilateral implantation（unilateral group）,and 22 eyes of 11 patients had normal bilateral implantation（bilateral group）. Patients' background,improvement of uncorrected visual acuity for near and far vision,severity of halo,glare and waxy vision,and patient's satisfaction were assessed and compared between the two groups. Results：Unilateral group was younger than bilateral group（average age were 43.2±8.0 and 69.8±9.2,respectively（p＜0.05））. Postoperative uncorrected far and near visual acuity improved in both group. Halo and glare were mentioned by 80％ in both group,but nobody complained about it. All patients were satisfied with the result. Conclusion：Unilateral implantation of multifocal IOL is an efficient procedure
