Abstract
PURPOSE
Methods of intraocular lens (IOL) calculations for cataract surgery after myopic corneal refractive surgery were compared. METHODS: The medical records of 23 eyes from 20 patients were retrospectively analyzed. Five methods - Haigis L and Barrett no history method from Post-Refractive IOL Calculator of American Society of Cataract and Refractive Surgery (ASCRS), Shammas no history method, Haigis suite from IOL Master 700, and clinical history method - were used. RESULTS: The Barrette no history method from the ASCRS showed the lowest arithmetic errors, while the Haigis-L from the ASCRS showed the lowest absolute prediction errors (−0.38 ± 0.99 diopters [D] and 0.76 ± 0.68 D, respectively). The percentages of refractive prediction errors within 0.50 D and 1.00 D of the Barrett no history method were 52.2% and 82.6%, respectively. CONCLUSIONS: The Barrette no history method and Haigis-L from the ASCRS showed the smallest errors in this study. The Barrett no history method showed a high percentage of refractive prediction errors within 0.50 D and 1.00 D.
