エビデンス |
水晶体に混濁が進行している人では、グレア光下での視力およびコントラスト感度が有意に低下している1,2,3,4,5)(IV-V)。
早期の白内障患者のグレアによる障害が、白内障がない症例と比較して有意に大きいという確証はない5,6,7,8)(IV)。
術前のグレアの程度と手術後の満足度についての相関関係は証明されていない3)(IV)。 | | | 1) | Superstein R, Boyaner D, Overbury O: Functional complaints, visual acuity, spatial contrast sensitivity, and glare disability in preoperative and postoperative cataract patients.
