  1. Values are means with standard deviations (SD) in parentheses expressed both as Snellen units as well as LOGarithm of Minimal Angle of Resolution (LogMAR) units. Group A = patients with only one eye operated; Group B = patients with both eyes operated during follow-up; Group C = patients who had had their first eye operated earlier and now the second eye was operated.
