Primary outcomes

  1. High Contrast Distance Visual Acuity (logMAR)

    Time frame: Day 1 Dispense, Day 7 Follow-Up

    Distance visual acuity (VA) testing was performed using letter charts. Each row of the chart contained 5 letters, with the letters on each row progressively smaller than the row above. The subject read the letters from larger to smaller. The test terminated when the subject either misidentified a majority of letters on 1 row or progressed to the smallest row of letters. Visual acuity scoring sheets were used to record the number of letters correctly read. LogMAR VA was calculated based on the total number of letters read incorrectly as follows: LogMAR Acuity = base reading + (0.02 x number of letters missed). A lower logMAR value indicates better VA.
