Figure 2

Equivalent reading (EKR) histogram to demonstrate the improved outcome following T-CAT. (a) EKR histogram of case 3 is shown preoperatively with broader base extending from 37 D to 43 D with two peaks. (b) Postoperatively, the EKR histogram shows a tall peak with a narrow base extending from 37 D to less than 40 D. (c) The EKR histogram of case 6 is shown preoperatively with broader base extending from 28.5 D to 42 D. (d) Postoperatively, the EKR histogram shows a narrow base from 32.5 D to 36.5 D with two peaks.
