In their letter published in the April issue of the ARCHIVES, Rosa and Capasso1 question the accuracy of the refraction in a number of patients in our study, 2 based on the fact that they expected another outcome in refraction after intraocular lens (IOL) exchange, when taking into account the change in IOL power (Table 2).2(p435) In general, a smaller amount of change in refraction is indeed expected than the amount of change in diopters (D) of IOL power after IOL exchange. We rechecked the files and found that there was no printing error. We can therefore only guess what the cause of this discrepancy is, especially in the left eye of patient 2 and the right eye of patient 3.
