Gender differences in refraction prediction error of five formulas for cataract surgery

Abstract Objectives To evaluate gender differences in optical biometry measurements and lens power calculations. Methods Eight thousand four hundred thirty-one eyes of five nineteen patients who underwent cataract surgery at University Michigan’s Kellogg Eye Center were included this retrospective study. Data including age, gender, biometry, postoperative refraction, implanted intraocular (IOL) power, IOL formula refraction predictions gathered and/or calculated utilizing the Sight Outcomes Research Collaborative (SOURCE) database analyzed. Results There was a statistical difference between every measure genders. Despite constant optimization, mean signed prediction errors (SPEs) modern formulas differed significantly genders, with skewed more hyperopic for males myopic females all 5 tested. Optimization constants by decreased error 2 Conclusions Gender found to be an independent predictor studied. can decrease certain formulas.
