Primary outcomes

  1. Subjective Overall Comfort Composite Score

    Time frame: Up to 1 month Follow-up

    Subjective Overall Comfort was evaluated using the Contact Lens User Experience Comfort scores (CLUE). CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.Range is 0 to 120. CLUE was collect at Baseline, Post Lens Fit 1-, 2-, 3- and 4- week follow-ups.

  2. Overall Comfort Individual Item

    Time frame: 1 month follow-up

    Overall Comfort was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Responses are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.

  3. Comfort at the End of the Day Individual Item

    Time frame: 1 month Follow-up

    Comfort at the End of the Day was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 like-rt scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.

  4. Comfort Each and Everyday Individual Item

    Time frame: 1 month Follow-up

    Comfort each and everyday was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.

  5. Frequency of Lens Awareness Individual Item

    Time frame: 1 month Follow-up

    Frequency of Lens Awareness was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are scaled as (Always, Frequently, Occasionally, Rarely, Never or Don't Know). Only the number of participants that reported Rarely or Never (Top-Two-Box) was reported here.

  6. Frequency of Experiencing Dryness Individual Item

    Time frame: 1 month Follow-up

    Frequency of Experiencing Dryness was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are scaled as (Always, Frequently, Occasionally, Rarely, Never or Don't Know). Only the number of participants that reported Rarely or Never (Top-Two-Box) was reported here.

  7. Making Your Eyes Feel Moist Throughout the Day Individual Item

    Time frame: Up to 1 month Follow-up

    Making your eyes feel moist throughout the day was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the percentage of participants that reported Excellent or Very good (Top-Two-Box) was reported here.

Secondary outcomes

  1. Subjective Overall Quality of Vision Composite Score

    Time frame: Up to 1 month Follow-up

    Subjective Overall Quality of Vision was evaluated using the Contact Lens User Experience Comfort scores (CLUE). CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response. CLUE was collect at Baseline, Post Lens Fit 1-, 2-, 3- and 4- week follow-ups.

  2. Overall Quality of Vision Individual Item

    Time frame: Up to 1 month Follow-up

    Overall Quality of Vision was assessed using a questionnaire item at Baseline, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor). Only the number of participants that reported Excellent or Very good (Top-Two-Box) was reported here.

  3. Overall Opinion Individual Item

    Time frame: Up to 1 month Follow-up

    Overall Opinion was assessed using a questionnaire item at Post Fit, 1-week, 2-week, 3-week and 4-week follow-up. Reposes are on a 5 likert scale (Excellent, Very Good, Good, Fair and Poor).
