Figure 1

Distribution of astigmatism prediction error. Using postoperative keratometrics for calculation reduces prediction error compared with using preoperative keratometrics considering surgically induced astigmatism. More than 90% of the patients have a prediction error of < 1.0 D with postoperative keratometrics. This trend is observed in both the 2.4- and 3.3-mm groups. D diopter, pre-op preoperative, post-op postoperative.
