结局指标
主要结局
Patient-reported Comfort at at the Manufacturer's Recommended Lens Replacement Timeframe of 2-weeks (Senofilcon A) or 4-weeks (Balafilcon A).
时间窗: after 4 weeks of lens wear
Subjective rating of overall comfort using a 0 through 5 scale. 0=n/a, 1=poor, 2=fair, 3=good, 4=very good, 5=excellent. Scores from 2-week and 4-week visits were combined for final values.
