    Accuracy of IOL Power Calculation Formulas for Quadrifocal Acrysof IQ PanOptix TFNT Implantation in Patients With Previous Corneal Refractive Surgery: Comparison of SS-OCT-Based Biometers

    Purpose: To evaluate the accuracy of intraocular lens (IOL) power calculation formulas from two biometers using swept-source optical coherence tomography for quadrifocal Acrysof IQ Panoptix TFNT IOL (Alcon Laboratories, Inc) implantation in patients with visually significant cataract with previous corneal refractive surgery. Methods: This retrospective study comprised 50 eyes from 50 patients with a history of corneal refractive surgery and TFNT IOL implantation. Candidate formulas were Shammas-PL and Barrett True-K in the Argos (Movu, Inc), Barret True-K and Haigis-L in the IOLMaster 700 (Carl Zeiss Meditec AG), and Haigis using the total keratometry (TK) mode in the IOLMaster 700. The ...
