Purpose: To analyze and compare refractive error changes according to different haptic intraocular lenses, after cataract surgery. Methods: We retrospectively reviewed the medical records of 508 eyes of 254 subjects who underwent cataract surgeries in both eyes, with one eye using the MBI® SAL302AC(C loop haptic IOL), and the other using the Zeiss® CT ASPHINA509M (plate haptic IOL). By using Barrett Universal II formula, prediction errors were calculated at 1 week, 2 weeks, 1 month, 2 months and 6 months after the surgery. Results: In the C loop group, prediction error was -0.26 ± 0.42 D at postoperative 1 week, -0.17 ± 0.45 D at postoperative 2 weeks. Hyperopic shift which reduced myopia progressed until postoperative 2 weeks (p<0.001), and then there was no significant shift after postoperative 2 weeks. In the plate group, prediction error was -0.37 ± 0.45 D at postoperative 1 week, -0.25 ± 0.44 D at postoperative 2 weeks, -0.11 ± 0.44 D at postoperative 1 month, -0.04 ± 0.44 D at postoperative 2 months. Hyperopic shift progressed at postoperative 2 weeks (p<0.001), 1 month (p<0.001), 2 months (p=0.02), and then there was no significant shift after postoperative 2 months. There were no significant differences between the two groups in the mean and median absolute error at postoperative 2 months.Conclusions: In both the C loop and plate groups, refraction was myopic at postoperative 1 week, and then the C loop group progressed hyperopic shift until postoperative 2 weeks, and the plate group progressed hyperopic shift until postoperative 2 months. At postoperative 2 months, prediction error of the plate group shows more hyperopic tendency than the C loop group, but there was no significant difference between the two groups in accuracy based on the absolute.
