Severity of visual impairment was determined by presenting visual acuity in worse-seeing cataract-operated eye.
†
Uncorrected refractive error was defined as cataract-operated eye having visual impairment when measured by presenting visual acuity (visual acuity ≤ 20/40), but no visual impairment when measured by best-corrected visual acuity (visual acuity > 20/40).
