Mean: mean
post-operative visual acuity, StDev: Standard
deviation, AvChange: Average change in acuity as a
result of cataract surgery, UAVA: Unaided visual acuity, PHVA: Pinhole visual
acuity, BCVA: Best corrected visual acuity, OptVA: Best
measure of visual acuity recorded, p: p value, Group 1: Eyes with
pre-operatively observed visually consequential ocular co-morbidity, Group 2: Eyes
with no pre-operatively observed visually consequential co-morbidity; Group 3,
operated eyes which experienced a post-operative complication
