LogMAR gain: Insufficient parameter to conclude HbA1c levels do not affect cataract surgery outcomes

In their recent paper, Liu et  al.1 reported that patients gained an equal amount of lines of corrected distance visual acuity (CDVA) after cataract surgery regardless of the presence of diabetes and diabetic retinopathy (DR) status. Furthermore, the gain in CDVA was independent of the patients' preoperative serum hemoglobin A1 c (HbA1c) levels. These conclusions were drawn by univariate and multivariate analysis of the following CDVA parameters: (1) the mean change in logarithm of the minimum angle of resolution (logMAR) units and (2) the proportion of eyes achieving a Snellen CDVA of 20/20.
