After optimizing IOL constants, the predicted refractive outcome was calculated for all formulas for each case. This was compared to the actual refractive outcome to provide the prediction error. The performance of CCS and FLACS was compared by the absolute prediction error and percentage of eyes within 0.25D, 0.5D and 1.0D of anticipated refractive outcome.Results: There was no statistically significant difference in median absolute error between the CCS and LACS groups for the Kane (0.256, 0.236; p=0.389), SRK T (0.298, 0.302, p=0.910), Holladay (0.312, 0.275; p=0.090), Hoffer Q (0.314, 0.289; p=0.330), Haigis (0.309, 0.258; p=0.177), Barrett Universal 2(0.250, 0.250; p=0.866), Holladay 2 (0.250, 0.258; p=0.860) and Olsen (0.260, 0.255; p=0.570) formulas. Similarly, there was no consistent difference between the two techniques for percentage of patients within 0.25, 0.50 and 1.0D of predicted refractive outcome for each formula.Conclusion: There was no difference in refractive outcome prediction accuracy between the CCS and FLACS techniques.Keywords: femtosecond laser-assisted cataract surgery, refractive predictability, IOL formulasConnell BJKane JXVajpayee RBDove Medical Pressarticlefemtosecond laser-assisted cataract surgeryrefractive predictabilityiol formulasOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 899-907 (2021)
