2.4mm耳側角膜切開における白内障手術前後の乱視量変化

Changes in corneal astigmatism after cataract surgery through 2.4 mm temporal corneal incision

要約　目的：2.4mm耳側角膜切開による白内障手術前後での角膜乱視の変化の報告。対象と方法：2.4mm耳側角膜切開による白内障手術を行った33例39眼を対象とした。倒乱視，直乱視，斜乱視の3群に分け，乱視量と乱視軸の変化を術後8週まで測定した。結果：角膜の乱視量と乱視軸には手術前後で有意差がなく，倒乱視，直乱視，斜乱視の3群間に有意差がなかった。結論：2.4mm耳側角膜切開による白内障手術では，術後8週までは角膜乱視の量と乱視軸に有意な変化がなかった。

Abstract.　Purpose：To report changes in corneal astigmatism after cataract surgery through 2.4 mm temporal corneal incision. Cases and Method：This study was made on 39 eyes of 33 patients who received cataract surgery through 2.4 mm incision through temporal clear cornea. They were divided into 3 groups：regular,inverse,and oblique astigmatism. They were followed up for 8 weeks after surgery regarding the amount and axis of corneal astigmatism. Results：There was no change in the amount and axis of astigmatism after surgery. There was no significant difference among the 3 groups. Conclusion：Cataract surgery through 2.4 mm temporal corneal incision did not result in changes in the amount or axis of corneal astigmatism for up to 8 weeks.
