Difference of the power vector components from the preoperative measurement with the IOLMaster 700 (IOLM) or the Casia2 (CASIA) to the postoperative measurement with the CASIA.

Decompositions into power vectors were performed for the corneal front and back surface power, for the keratometric power, and for the total keratometry (IOLM) and real power (CASIA). The power vector components in 45°/135° were reversed in sign for all left eyes in our dataset in order to present the data in the same orientation as for right eyes. Mean, SD, Median, and 2.5% / 97.5% refer to the arithmetic mean, standard deviation, median, and the lower and upper bounds of the 95% confidence interval respectively.
