Summary

The purpose of this study was 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 was assessed.

Detailed description

Each participant wore 3 brands of contact lenses in a randomized, cross-over fashion, with a washout phase of at least 1 night between brands.
