RESUMO

PURPOSE: To determine the predictability of different intraocular lens (IOL) power calculation formulas (SRK-II, Binkhorst-II, Hoffer Q, Holladay y SRK/T) according to the axial length (AL). METHOD: The residual refractive error for each formula was determined in 212 cases of phacoemulsification with IOL implantation and it was compared to the <> result (the ideal result was emmetropia in all cases). RESULTS: The refractive error obtained with all different formulas for the AL group between 22 and 28 mm was not statistically significant. The error between the AL group of <22 mm and the AL group between 22-28 mm was not statistically significant for Binkhorst-II and Hoffer Q formulas. The error between the AL group > 28 mm and the group between 22-28 mm was not statistically significant for SRK/T. CONCLUSION: For small eyes (<22 mm) the Binkhorst-II and Hoffer Q formulas provided the best predictive results, whereas in long eyes (>28 mm) the SRK/T is the most accurate.
