ABSTRACT
Corneal astigmatism includes anterior astigmatism (AA) and posterior astigmatism (PA).According to the hterature,85.0%-96.1% PA ranging from-0.01 to-1.10 D refers to astigmatism against the rule.With the age increasing,PA shows a significant trend from astigmatism against the rule to with the rule,while AA shows toward against-the-rule astigmatism.Therefore,PA often leads to partially decrease of total astigmatism (TA) in young adults,but the increase of TA in aged elderly.Clinically,ignorance of PA will lead to a false estimate of TA,thereby affecting visual quality after refractive cataract surgery.And this article aims to introduce the measurement of PA and its clinical significance for providing the reference in clinical practices.
