结局指标
主要结局
Percentage of Participants Who Develop Macular Edema Within 90 Days Following Cataract Surgery (Day 0)
时间窗: 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.
Percentage of Participants With Best-corrected Visual Acuity (BCVA) Improvement of ≥ 15 Letters From Preoperative Baseline to Day 14 and Maintained Through Day 90
时间窗: 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.
次要结局
- Percentage of Participants With BCVA Improvement of ≥ 15 Letters From Preoperative Baseline to Day 90(Baseline to Day 90)
- Percentage of Participants With BCVA Improvement of ≥ 15 Letters From Preoperative Baseline to Day 60(Baseline to Day 60)
- Percentage of Participants With a > 5-letter Loss in BCVA From Day 7 to Any Visit [Time Frame: Day 7 up to Any Visit](Day 7 up to any visit through Day 90)
- Percentage of Participants With With a > 10-letter Loss in BCVA From Day 7 to Any Visit(Day 7 up to any visit through Day 90)
