Study Summary
The primary objective of this study is to evaluate the overall clinical performance of an investigational silicone hydrogel contact lens over 7 days of daily wear.
Primary Outcome
Front surface wettability (i.e., assessment of the disruption of the front surface wettability of the contact lens) was assessed by the investigator for each eye individually. Front surface wettability was collected on a 5-point scale, where where Grade 0 = a smooth uniformly reflecting surface, Grade 1 = a coarse hazy surface which seems resolved momentarily with each blink and becomes exacerbated with staring, Grade 2 = one stable dry (non-wetting) area of some magnitude, Grade 3 = more than o
