Measure
Etafilcon A/ Nelfilcon A/Filcon II 3
etafilcon A worn first, nelfilcon A worn second, Filcon II 3 worn third. Only etafilcon A and nelfilcon A were used in phase I of the study per study protocol, with Filcon II 3 being added to the rotation in Phase II (see outcome 5).
Nelfilcon A/ Etafilcon A/ Filcon II 3
nelfilcon A worn first, etafilcon A worn second, Filcon II 3 worn third. Only etafilcon A and nelfilcon A were used in phase I of the study per study protocol, with Filcon II 3 being added to the rotation in Phase II (see outcome 5).

PRIMARY outcome

Timeframe: At 1-min after lens insertion during Phase I

Population: Subjects included in the analysis were those who were enrolled, randomized, and completed the study.
