  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. Patients with minor preoperative seeing problems = levels 1 and 2 of the seeing dimension; patients with significant preoperative seeing problems = levels 3 – 5 of the seeing dimension.
