Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Best-corrected Visual Acuity (BCVA) Improvement of ≥ 15 Letters From Preoperative Baseline to Day 14 and Maintained Through Day 90
Time Frame: Baseline to Day 14, and maintained through Day 90
BCVA (with spectacles or other visual corrective devices) was reported in letters read correctly, using the Early Treatment Diabetic Retinopathy Study (ETDRS) test of 70 letters. Improvement of BCVA was defined as an increase (gain) in the number of letters read, compared to the baseline assessment. One eye (study eye) contributed to the analysis.
Baseline to Day 14, and maintained through Day 90
Percentage of Participants Who Develop Macular Edema Within 90 Days Following Cataract Surgery (Day 0)
Time Frame: Day 0 to Day 90
Macular edema was defined as ≥ 30% Increase from pre-operative baseline in central subfield macular thickness, as measured with Spectral Domain Ocular Coherence Tomography (SD-OCT). One eye (study eye) contributed to the analysis.
Day 0 to Day 90
