Outcome

Type Measure Description Time frame Safety issue
Primary Binocular Visual Acuity (logMAR) Binocular visual acuity was measured on a logMAR (Logarithm of Minimal Angle of Resolution) scale and was evaluated at distance (4 meters), intermediate (64 cm) and near (40 cm) under high lumiance high contrast lighting conditions using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. The room illuminance was required to be beetween 7.3 and 7.9 EV (394-597 lux). For Distance (4 meters), the acceptable range for the chart luminance was 10.5-10.7 EV (181-208 cd/m2). For Intermediate (64 cm) and Near (40cm), the acceptable range for the chart luminance 10.8-11.1 EV (223-274 cd/m2). Letter-by-letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR visual performance score of 0.0 is equivalent to Snellen visual acuity of 20/20. 1-Week Follow-up
Secondary Subjective Overall Vision Scores Overall vision scores were assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patientexperience 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 with a range of 0-120. The average CLUE vision score for each lens type was reported. 1- Week Follow-up
