Abstract

Background& Purpose: IOL power calculation is one of the current problems in cataract surgery. This study was performed to evaluate the accuracy of six IOL power calculation formulas in patients undergoing SENILE CATARACT surgery.Patients & Methods: This was a clinical trial on 61 eyes in 58 patients with SENILE CATARACT.All eyes underwent uncomplicated phacoemulsification or extracapsular cataract extraction and posterior chamber intraocular lens (PCIOL) implantation.Final refraction was performed 6 months after surgery; absolute refractive error was calculated as observed error minus expected error. Eyes were divided into three groups regarding axial length: <22mm, 22-24.5 mm and >24.5mm. Results were analyzed using the ANOVA and LSD tests.Results: Out of 58 cases, 32 subjects (55.0%) were male and (45.0%) were female. Patients age ranged from 35-80 y (mean 65±11.2 y) overall mean absolute error was 1.09±0.67 and there was no significant difference among the six formulas. In eyes of short axial length SRKI yielded better results in terms of final absolute error (P<0.05) However in medium and long eyes no significant difference was observed among the six formulas.Conclusion: Overall, the mean absolute errors of the six formulas were similar. We suggest that the choice of IOL calculation formulas should be based on availability, familiarity and simplicity; a higher level of caution should be considered in short eyes.
