Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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.

  2. 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.


Secondary Outcome Measures :
  1. Percentage of Participants With BCVA Improvement of ≥ 15 Letters From Preoperative Baseline to Day 90 [ Time Frame: Baseline to Day 90 ]
  2. Percentage of Participants With BCVA Improvement of ≥ 15 Letters From Preoperative Baseline to Day 60 [ Time Frame: Baseline to Day 60 ]
  3. Percentage of Participants With a > 5-letter Loss in BCVA From Day 7 to Any Visit [Time Frame: Day 7 up to Any Visit] [ Time Frame: Day 7 up to any visit through Day 90 ]
  4. Percentage of Participants With With a > 10-letter Loss in BCVA From Day 7 to Any Visit [ Time Frame: Day 7 up to any visit through Day 90 ]
