Comparison of the accuracy of six intraocular lens power calculation methods in post-myopic-LASIK eyes.

ABSTRACT:

Objectives

To compare the accuracy of six intraocular lens (IOL) power calculation methods in post-myopic-LASIK eyes.

Methods

Post-myopic-LASIK patients scheduled for cataract surgery were enrolled. Mean error (ME), mean absolute error (MAE), and median absolute error (MedAE) of ASCRS (ASCRS-Max, ASCRS-Average, ASCRS-Min), EVO 2.0, Pearl-DGS, Barrett True-K no-history, Shammas-PL, and Haigis-L were compared. The ASCRS method employed four formulas, including Shammas-PL, Haigis-L, Potvin-Hill Pentacam, and Barrett True-K no-history. Trueness, precision, and accuracy indices were evaluated by comparing trimmed-mean values with heteroscedasticity adjustment. Subgroup analyses were performed based on K value, axial length (AL), and corneal decentered ablation, respectively. Fact
