要約 目的:屈折矯正のために眼鏡を処方され,処方の変更がその後必要になった事例の検討。対象と方法:都市部にある2眼科施設で過去7か月間に発行された39,290の眼鏡処方を検索した。男女ともほぼ同数で,平均年齢は40歳であった。眼鏡の用途は遠用が約70%であり,残りが近用または遠近両用であった。結果:発行後6か月以内に1,193(3.0%)の処方が変更された。処方の変更は男女間に差はなく,遠用よりも近用または遠近両用などの多焦点レンズで頻度が高かった。処方の変更は10歳代前半と70歳代で多かった。結論:眼鏡処方は自覚的検査が重要な要因になるので,処方の変更は避けられない。年齢によりその内容に特徴がある。

Their age averaged about 40 years. Eyeglasses were for distant vision in 70% of cases. Results:A total of 1,193 prescriptions(3.0%)needed modifications within 6 months. There was no gender-related differences. Modification was needed for eyeglasses for near and bifocals than those for distant vision. Modification was more frequent for persons in low-teens and septuagenarians. Conclusion:Eyeglass prescriptions had to be modified in about 3% of instances. The causes differed depending on the age.
