Trial Outcomes & Findings for Lubricity Post-Wear - Competitive Lenses Pilot (NCT NCT02402127)

NCT ID: NCT02402127

Last Updated: 2016-09-02

Results Overview

Worn contact lenses were removed from the participant's eye and the coefficient of friction was measured by the inclined plane method. A lower coefficient of friction may indicate higher contact lens lubricity. The ex-vivo lubricity was carried out on one lens (one eye) only.

PRIMARY outcome

Timeframe: Day 1, Hour 16, each product

Population: Intention to treat participants with non-missing observations

Worn contact lenses were removed from the participant's eye and the coefficient of friction was measured by the inclined plane method. A lower coefficient of friction may indicate higher contact lens lubricity. The ex-vivo lubricity was carried out on one lens (one eye) only.

SECONDARY outcome

Timeframe: Day 1 (each product)

Population: Intention to treat participants with non-missing observations

Unworn contact lenses were removed from the commercial packaging and the coefficient of friction of the unworn lenses was measured by the inclined plane method. A lower coefficient of friction may indicate higher contact lens lubricity.
