目的:沖縄県人には浅前房が多く,白内障手術で角膜内皮障害の危険が大きいため,ソフトシェル法の内皮障害保護効果を検討した。対象:4年間に超音波白内障手術を行った1,015眼のうち,術後3か月目に角膜内皮細胞密度を測定できた450眼を対象とした。ソフトシェル法を181眼,単独凝集型粘弾性物質を269眼に用いた。結果:角膜内皮細胞減少率は,ソフトシェル群が8.6%,単独凝集型粘弾性物質群が12.6%であり,有意差があった(p=0.02)。核硬度がEmery-Little分類の1~3度の422眼ではそれぞれ7.6%と12.3%であり,有意差があった(p=0.03)。浅前房182眼ではそれぞれ8.9%と16.2%であり,有意差があった(p=0.02)。ストレスインデックスはそれぞれ33.3と49.2であり,両群間に有意差があった(p=0.02)。核硬度が1~3度の症例ではそれぞれ31.1と47.1であり,両群間に有意差があった(p=0.03)。浅前房眼ではそれぞれ35.7と77.3であり,有意差があった(p=0.03)。結論:白内障手術でのソフトシェル法は浅前房眼と核硬度が1~3度の眼に対し角膜内皮保護効果がある。
Purpose:Inhabitants in Okinawa have a high incidence of shallow anterior chamber. This feature may mean a higher risk of corneal endothelial damage during cataract surgery. We evaluated the value of soft-shell technique in protecting the corneal endothelium. Cases:This retrospective study involved 450 eyes that received cataract surgery in the past 4 years. All the eyes were examined for corneal endothelial cells before and 3 months after surgery. Soft-shell technique was used in 181 eyes and cohesive viscoelastic substance in 269 eyes. Results:Corneal endothelial cells decreased by 8.6% in soft shell group and 16.2% in viscoelastic group. The difference was significant(p=0.02). Similar findings were obtained in 182 eyes with shallow anterior chamber,and in 422 eyes with nuclear hardness ranging from grade 1 to 3 after Emery-Little. Stress index was 31.1 in soft-shell group and 47.1 in the other. The difference was significant(p=0.03). Conclusion:Soft-shell technique protects the corneal endothelium during cataract surgery in eyes with shallow anterior chamber and in eyes with nuclear hardness ranging from grade 1 to 3.
