Outcome Measures

Primary Outcomes (6)

  • Lens Fit - Decentration After Insertion

    The ophthalmologist's objective assessment of lens fit measurement of decentration after insertion (20 minutes settling) of Pair #1 (measured at baseline visit) and Pair #2 (measured at 7 days after baseline visit). (mm, horizontal and vertical).

    Baseline and 7 days from baseline visit

  • Lens Fit - Decentration at One Week

    The ophthalmologist's objective assessment of lens fit measurement of decentration of Pair #1 (measured at 7 days after baseline visit) and Pair #2 (measured at 14 days after baseline visit). Each pair worn for one week daily disposable wear basis (at least 8 hours per day, 7 days per week). Lenses worn minimum 2 hours prior to visit. (mm, horizontal and vertical).

    7 days and 14 days from baseline visit

  • Lens Fit - Tightness After Insertion

    The ophthalmologist's rating of lens fit measurement of push-up tightness after insertion (20 minutes settling) of Pair #1 (measured at baseline visit) and Pair #2 (measured at 7 days after baseline visit). (0-100%, 5% steps, 0%=excessively loose, 50%=optimum, 100%=excessively tight ).

    Baseline and 7 days from baseline visit

  • Lens Fit - Tightness at One Week

    The ophthalmologist's rating of lens fit measurement of push-up tightness of Pair #1 (measured at 7 days after baseline visit) and Pair #2 (measured at 14 days after baseline visit). Each pair worn for one week daily disposable wear basis (at least 8 hours per day, 7 days per week). Lenses worn minimum 2 hours prior to visit. (0-100%, 5% steps, 0%=excessively loose, 50%=optimum, 100%=excessively tight ).

    7 days and 14 days from baseline visit

  • Lens Fit - Post-Blink Lens Movement After Insertion

    The ophthalmologist's objective assessment of lens fit measurement of post-blink lens movement after insertion (20 minutes settling) of Pair #1 (measured at baseline visit) and Pair #2 (measured at 7 days after baseline visit). (mm).

    Baseline and 7 days from baseline visit

  • Lens Fit - Post-Blink Lens Movement Prior to Removal

    The ophthalmologist's objective assessment of lens fit measurement of post-blink lens movement prior to removal of Pair #1 (measured at 7 days after baseline visit) and Pair #2 (measured at 14 days after baseline visit). (mm).

    7 days and 14 days from baseline visit

Secondary Outcomes (7)

  • Overall Preference - Comfort After Insertion

    14 days from baseline visit

  • Overall Preference - Comfort Before Removal

    14 days from baseline visit

  • Overall Preference - Dryness After Insertion

    14 days from baseline visit

  • Overall Preference - Dryness Before Removal

    14 days from baseline visit

  • Overall Preference - Handling, Inserting

    14 days from baseline visit

  • +2 more secondary outcomes
