*P < 0.05, Pearson’s product–moment correlation.

Male = 1, female = 0, diabetic = 1, non-diabetic = 0.

^AChanges in values (Δ) were calculated by subtracting preoperative values from values obtained 2 months after surgery. All values were adjusted for age and sex.

LogMAR, logarithm of the minimum angle of resolution; VFQ-25, visual function questionnaire 25; BMI, body mass index; SBP, systolic blood pressure.
