Resumen

DONOSO, R; MURA, JJ; LOPEZ, M  y  PAPIC, A. Emmetropization at cataract surgery. Looking for  the best IOL power calculation formula according  to the eye length. Arch Soc Esp Oftalmol [online]. 2003, vol.78, n.9, pp.477-480. ISSN 0365-6691.

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 «ideal» 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.
