Primary Outcome Measures:
  • Monocular Contact Lens Snellen Visual Acuity Worse Than 20/40 [ Time Frame: Follow-up Visits- 24 hr, 1, 4, 12, 24,36, and 52 weeks ]
    Percentage of subject eyes reported with visual acuity worse than 20/40 at each study visit.

  • Rate of Contact Lens Related Serious and Significant Events (SSE) [ Time Frame: Throughout the duration of the study (1 Year) ]
    The number of Contact-Lens related Serious and Significant Adverse Events were reported for each study lens. The incidence of rates of contact-lens related SSEs were calculated as (# of subjects that experienced an event)/(total # subjects). If there were multiple diagnostic findings, the event was categorized under the highest event level diagnostic.
