Accuracy of Toric Intraocular Lens Calculations Using Estimated Versus Measured Posterior Corneal Astigmatism.

Purpose: To compare the prediction accuracy of toric intraocular lens calculations using estimated vs measured posterior corneal astigmatism (PCA).

Design: Retrospective case series.

Methods: A total of 110 eyes of 110 patients with uncomplicated toric intraocular lens implantation were included in this study.
