- Primary Outcome Measures
Name Time Method Lens Fit Acceptance 10-15 minutes post lens fit Lens fit acceptance (whether acceptable or unacceptable) was assessed by the Investigator at dispensing.
- Secondary Outcome Measures
Name Time Method Binocular Snellen Visual Acuity (VA) 10-15 minutes post lens fit Binocular Snellen VA was assessed at dispensing by Investigator using a Snellen vision chart. Subjects were analyzed based on their performance on a Snellen Vision chart exam in the study lenses in an effort to measure how well the lenses perform for vision correction.
Corneal Staining After 6-9 days of lens wear Corneal staining type was graded in a 5-point scale over the 5 corneal regions by Investigator using a slit lamp; 0=none, 1=trace, 2=mild, 3=moderate, and 4=severe. Maximum grade of corneal staining type over the 5 corneal regions was categorized either absence or presence of corneal staining for the analysis.
