Abstract. Purpose:To evaluate the accuracy of formulas for the calculation of power of intraocular lens for eyes with short axial length. Cases and Method:This retrospective study was made on 84 eyes that received cataract surgery in the past 5 years. All the eyes had axial length between 20.78 to 21.99 mm. Postoperative refraction was compared with the outcome of SRK/T,Haigis and Holladay formulas. Results:Postoperative error of refraction was the minimum when calculated by SRK/T or Haigis formulas usisng IOLMaster,and by Holladay formula using A-mode measurement. Postoperative refraction shifted towards hyperopia by 0.7 diopters using A mode than IOLMaster calculated by each of 3 formulas. Conclusion:Accuracy of calculated power of intraocular lens was the greatest by measuring with IOLMaster and calculated by SRK/T or Haigis formulas in eyes with short axial length.
