Subjective Comparison of Pre-Lens Tear Film Stability With Daily Disposable Contact Lenses Using Ring Mire Projection
The purpose of this study is to compare three CE-marked daily disposable contact lenses for
tear film stability as measured by pre-lens non-invasive keratograph break up time (PL
NIK-BUT). Secondarily, contact lens surface wettability will be assessed. Each participant
will wear three brands of contact lenses in a randomized, cross-over fashion.
Inclusion Criteria:
- Sign Informed Consent.
- Adapted contact lens wearer.
- Willing to wear contact lenses up to 12 hours and attend all study visits.
- Vision correctable to 0.1 (logMAR) or better in each eye at distance with pre-study
lenses at Visit 1.
- Other protocol-defined inclusion criteria may apply.
Exclusion Criteria:
- Any ocular infection, inflammation, abnormality, or active disease that would
contraindicate contact lens wear.
- Any use of systemic or ocular medications that would contraindicate contact lens
wear.
- Any ocular finding observed during the Visit 1 examination that would contraindicate
contact lens wear.
- Monocular subjects (only one eye with functional vision) or subjects fit with only
one lens.
- Known pregnancy.
- Participation in any clinical study within 30 days of Visit 1.
- Other protocol-defined exclusion criteria may apply.
