Barrett Universal Formula Ii 2025. The science behind Barrett Universal II formula accuracy of cataract surgery and examine the predictive factors of postoperative biometry prediction errors using the Barrett Universal II (BUII) IOL formula for calculation. The Barrett Universal II formula predictions were stable across all variables, and the Holladay 2 formula performed similarly

This study aims to evaluate the accuracy of incorporating AXLsos in the aforementioned formulas, comparing results with and without the sum-of-segments option. 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.

9 The BUII formula is an update to the Barrett Universal I formula, 10 and is frequently used to determine IOL power. Studies have reported good refractive accuracy using the BUII formula in eyes with. Patient Data ; Universal Formula ; Formula Guide Enter Data and Calculate Doctor Name: Patient Name : Patient ID: Lens Factor (-2.0~5.0) or A Constant (112~125) Measurements: OD: OS: Axial Length (R) (12~38 mm) Axial Length.
A constant to Lens Factor (LF) conversion for Barrett. 9 The BUII formula is an update to the Barrett Universal I formula, 10 and is frequently used to determine IOL power. Optical biometers are available preprogrammed with IOL power formulas, such as the Barrett Universal Formula II "K" (BUII)
AsiaPacific Association of Cataract and Refractive Surgeons (APACRS). 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 The Barrett Universal II formula features a modified version, known as the BTAL formula, which is integrated into the ARGOS biometer and employs AXLsos
