Comparison of prediction accuracy of five different biometric formulas

Objective To compare the performance of Sanders-Retzlaff-Kraft/Theoretical, Hoffer Q, Barrett Universal II, Kane, and Hill-radial basis function formulas to calculate intraocular lens power in eyes with normal axial length, terms predicting target refraction by using partial coherence interferometry technology. Methods Phacoemulsification implantation were performed 135 patients an length between 22 24.5 mm. Axial keratometry, anterior chamber depth measured Master 500. [...]
