The mean absolute error in many of these studies ranged from 1.06 D to 1.4 D, 11,[18][19][20][21] which was greater than the mean absolute error of 0.5 D to 0.7 D found in adults. 22,23 In more recent studies, authors have found mean absolute prediction errors of 0.76 to 1.18 when they applied the adult IOL formulas to pediatric patients, 24,25 still with only 43% of eyes with less than 0.5 D of error.…”
