Purpose: To compare the refractive accuracy of the Barrett True axial length (BTAL) formula, newly integrated into ARGOS, with that of the Barrett Universal II (BUII) formula calculated using axial length (AL) from IOL Master 700 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. Methods: We assessed eyes of patients who underwent cataract surgery with.
