  • To facilitate interpretation of the results, visual acuity is mentioned in decimal notation. 0 = preoperative control; VCC = Snellen visual acuity with correction in decimal notation; *VAR = visual acuity rating; HCVA = high contrast visual acuity; LCVA = low contrast visual acuity; max G = maximum glare (3000 cd/m2); mid G = medium glare (800 cd/m2); min G = minimal glare (300 cd/m2); no G = no glare (only front illumination).
