Hill rbf constants
WebThe Hill-RBF Method is exclusively integrated in the Haag-Streit’s biometry devices such as the Lenstar 900. It is the first purely data driven IOL calculation technique incorporating pattern recognition based in artificial intelligence and sophisticated data interpolation. Hill-RBF features a unique reliability check providing confidence for ... WebWith proper lens constant optimization, the Barrett Universal II, EVO, and Hill-RBF 2.0 formulae were equally accurate in predicting IOL power across the entire range of axial lengths.
