Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall Comfort Scores
Time Frame: 1-week Follow-up
Overall comfort was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. 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 with a range of 0-120.
1-week Follow-up
Overall Vision Scores
Time Frame: 1-week Follow-up
Overall vision was assessed using the CLUE questionnaire. CLUE is a validated 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 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.
1-week Follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Average Daily Wear Time
Time Frame: 1-week Follow-up
Average daily wear time was calculated as the number of hours between subjects reported time of insertion and time of removal of the study lenses, on an average day, at 1-week follow-up evaluation. Higher wear times indicate better lens performance. The average wear time was reported for each lens type.
1-week Follow-up
LLHC LogMAR Visual Performance
Time Frame: 1-week Follow-up
Visual performance was calculated as monocular contact lens-corrected distance visual acuity using a logMAR visual acuity scale. This was evaluated under low luminance and high contrast conditions (LLHC) at 4 meters from Early Treatment Diabetic Retinopathy Study (ETDRS) charts at the 1-week follow-up visit. Lower visual performance values indicate better vision. Two measurements were performed for each eye at 1-week follow-up. The average visual performance was reported for each lens type.
1-week Follow-up
HLLC LogMAR Visual Performance
Time Frame: 1-week Follow-up
Visual performance was calculated as monocular contact lens-corrected distance visual acuity using a logMAR visual acuity scale. This was evaluated under high luminance and low contrast conditions (HLLC) at 4 meters from Early Treatment Diabetic Retinopathy Study (ETDRS) charts at the 1-week follow-up visit. Lower visual performance values indicate better vision. Two measurements were performed for each eye at 1-week follow-up. The average visual performance was reported for each lens type.
