To assess the refractive outcome of cataract surgery employing IOL master and A-scans in diabetic and non-diabetic patients

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.

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.

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.
