Participant Flow

Of the 60 subjects enrolled, 60 were fitted with the study lenses and completed the trial (i.e. no discontinuations).This study design considered a single-center, (Optometry Research Group), located at the University of Valencia Spain (target 60 subjects).

All subjects were habitual lens wearers.
