Comparing the Accuracy of the Kane, Barrett Universal II, Hill-Radial Basis Function, Emmetropia Verifying Optical, and Ladas Super Formula Intraocular Lens Power Calculation Formulas Clin Ophthalmol , 17 ( 2023 ) , pp The Barrett Universal II formula predictions were stable across all variables, and the Holladay 2 formula performed similarly
Barrett A Constant to Lens Factor conversion and Design Factor. Among several IOL power calculation formulas, the Barrett Universal II (BU-II) formula has been considered to be one of the most accurate formulas.[1,2,3,4,5,6,7] Using IOLMaster ® 700 (Carl Zeiss Meditec AG, Jena, Germany), cataract surgeons can now easily obtain refractive prediction, including with the BU-II formula.
