Study Summary
The objective of this study was to evaluate visual function of AcrySof Toric and AcrySof Natural Intraocular Lenses (IOLs) following implant for replacement of cataract.
Primary Outcome
Uncorrected Visual Acuity (UCVA) from surgery measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.
