This study is a data-based retrospective analysis using 5 formulas: Holladay I, Hoffer Q, SRK/T, Holladay II and Haigis to compare the accuracy of IOL power estimation, the mean absolute errors between postoperative and predictive refractions were compared among five most commonly used IOL power formulas. For the eyes with AL equal to 29 mm or shorter than 21 mm, the effect of Haigis formula performed better than other formulas. For other eyes, Haigis formula seemed to have similar accuracy with other formulae. In China, we suggest that it is better to use Haigis formula to predict the IOL power before cataract surgery.
