Aim Evaluate refractive outcomes of routine cataract surgery of a single surgeon. Compare accuracy of Barrett Universal-II (Barrett) and Hill Radial Basis Function 2.0 (Hill-RBF) intraocular lens formulas. Materials and Methods Single surgeon retrospective consecutive case series of 213 cataract operations with the AcrySof SN60WF implant from January 1, 2019 to December 31, 2019. Evaluation of the mean absolute error for Barrett and Hill-RBF. Percentage of eyes within ±0.25 diopters (D), ±0.5 D, and ±1.0 D of prediction error was calculated. Subgroup analysis by axial length, keratometry, and anterior chamber depth was also conducted. Results 94.4% of cases demonstrated final refraction within 0.5 D of target refraction. 91.5% and 92.5% of predictions by the Barrett and Hill-RBF were within 0.5 D of target spherical equivalence, respectively. No significant difference in mean absolute error was detected between the two formulas (Barrett 0.25 ±0.22 D; Hill-RBF 0.26 ±0.24 D; p = 0.71). However, subgroup analysis revealed significant difference in the performance of the two formulas in eyes with anterior chamber depth. 2.75mm (Barrett 0.23 ±0.16 D; Hill-RBF 0.35 ±0.28 D; p = 0.046). Conclusion Predictions of Barrett and Hill-RBF were within 0.5D of target spherical equivalence in > 90% of cases. Barrett found to be superior in eyes with ACD. 2.75mm.
