Primary Outcome Measures :
  1. Correlation Between Subjective CLUE Comfort and Keratometry [ Time Frame: 3-day follow-up ]
    CLUE- The Contact Lens User Evaluation (CLUE)™ questionnaire is a validated patient-reported outcomes questionnaire to assess patient experience attributes of soft, disposable 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) with a range of 0-120, where higher scores indicate a more favorable/positive response (Wirth, RJ. Et al. August 2016). Keratometry measurements of major keratometric meridians (diopter [DK]) and their location (degrees) was collected at baseline for both eyes. The correlation between CLUE comfort and maximum Keratometry measurements of the two eyes within each subject and the correlation between CLUE comfort and the minimum Keratometry measurements of the two eyes within each subject were reported.

  2. Correlation Between Subjective CLUE Comfort and Corneal Diameter [ Time Frame: 3-day follow-up ]
    Assessment The Contact Lens User Evaluation (CLUE)™ questionnaire is a validated patient-reported outcomes questionnaire to assess patient experience attributes of soft, disposable 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) with a range of 0-120, where higher scores indicate a more favorable/positive response (Wirth, RJ Et al. August 2016). Corneal diameter (horizontal visible iris diameter [HVID]) was collected at baseline for both eyes using a slit lamp reticle, measuring to the nearest 0.05 mm.The maximum (or minimum) measurements of HVID between the two eyes of each subject were used for correlation analyses between subjective CLUE comfort score and corneal diameter.
