Drs. Tuuminen and Grzybowski assert that the gain in logMAR is an “insufficient parameter to conclude HbA1c levels do not affect cataract surgery outcomes” because the baseline CDVA differs between diabetes subgroups. We agree that the gain in logMAR is an incomplete outcome measure; however, we disagree that it is inappropriate. The gain in logMAR acuity is t he gold standard in assessing surgical outcomes. Our controlled longitudinal risk-adjusted cohort study of more than 65 000 community-based patients showed that irrespective of the severity of the DR, the mean improvement in CDVA was 4.5 lines, a meaningful improvement for most, if not all, patien ts.
