Purpose: To assess the refractive outcome of cataract surgery employing IOL master and A-scans in diabetic and non-diabetic patients Methods: The retrospective comparative study included 205 eyes of consecutive patients who had uneventful cataract surgery implanting I-Flex IOL. Axial length was measured with IOL master and A-scan and IOL power was calculated using various formulas (SRK II, SRK/T, Haigis, Holladay). Subjects was separated into five groups according to axial length, and then the groups were divided into diabetic and non-diabetic subgroups. Differences between the predicted refraction and the actual refraction were compared and analyzed at two months after the operation. Results: The mean absolute errors (MAE) of ten groups showed no significant differences. Comparing diabetic groups and non-diabetic groups, there were no statistically significant differences. Also the result of the two modalities, IOL master and A-scan, were not different in statistical analysis. Conclusions: In diabetic and non-diabetic patients, IOL master and A-scan may be the accurate methods for calculating IOL power regardless of the axial length.
