What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
etafilcon ADevice
Also called etafilcon A (Daily Disposable Contact Lens)
Participants wear a first pair of lenses for two weeks and then crossover and wear an alternate second pair of lenses for two weeks.
stenfilcon ADevice
Also called stenfilcon A (Daily Disposable Contact Lens)
Participants wear a first pair of lenses for two weeks and then crossover and wear an alternate second pair of lenses for two weeks.
| Study group | Role | What they receive |
|---|---|---|
| stenfilcon A | Experimental | Participants wear a first pair of lenses for two weeks and then crossover and wear an alternate second pair of lenses for two weeks. Receives: Device: etafilcon A |

What is being measured
The primary outcome is the main question the study is designed to answer.
Handling
Participant's subjective rating for lens handling of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (0-10, 10= very easy).
Measured: two weeks and four weeks from baseline visit
Satisfaction With Handling
Participant's subjective rating for overall satisfaction of lens handling of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (5 point Likert scale - Completely Dissatisfied, Somewhat Dissatisfied, Neither, Somewhat Satisfied, Completely Satisfied).
Measured: two weeks and four weeks from baseline visit
Secondary outcomes (4)
Comfort
Participant's subjective rating for overall lens comfort of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (0-10, 10=can't feel).
Measured: two weeks and four weeks from baseline visit
Dryness
Participant's subjective rating for overall lens dryness of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (0-10, 10=no dryness).
Measured: two weeks and four weeks from baseline visit
Satisfaction With Dryness
Participant's subjective rating for overall satisfaction of lens dryness of Pair #1 surveyed at 2 weeks (+3) days after baseline visit and Pair #2 surveyed at 4 weeks (+3) days after baseline visit. Each pair worn for two weeks daily disposable wear basis (at least 40 hours per week). Lenses worn minimum 2 hours prior to visit. Rated by questionnaires (5 point Likert scale - Completely Dissatisfied, Somewhat Dissatisfied, Neither, Somewhat Satisfied, Completely Satisfied).
Measured: two weeks and four weeks from baseline visit
