About this study
Official title: Evaluation of the Lubricity of Daily Disposable Silicone Hydrogel Contact Lenses After Wear
The purpose of this study is to measure the coefficient of friction of three silicone hydrogel, daily disposable contact lenses after 16 hours of wear.
Read the detailed description
In this 3-treatment, 3-period, 6-sequence crossover study, each participant will wear all 3 products in randomized order, 1 product at a time, with a washout period of up to 7 days between treatment periods. Lenses will be collected for ex-vivo lubricity analysis. The ex-vivo lubricity analysis will be conducted under a separate non-clinical protocol.

What is being measured
The primary outcome is the main question the study is designed to answer.
Average Coefficient of Friction of Worn Lenses at 16 Hours
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.
Measured: Day 1, Hour 16, each product
Secondary outcomes (1)
Average Coefficient of Friction of Unworn Lenses
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.
Measured: Day 1 (each product)

Primary outcome
Average Coefficient of Friction of Worn Lenses at 16 Hours
Time frame: Day 1, Hour 16, each product
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.
1 secondary outcome
Average Coefficient of Friction of Unworn Lenses
Time frame: Day 1 (each product)

Questions about this trial
What is this clinical trial studying?
A study testing Narafilcon A contact lenses, Stenfilcon A contact lenses and Somofilcon A contact lenses in people with Refractive Error, run by Alcon Research.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Sep 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Average Coefficient of Friction of Worn Lenses at 16 Hours (time frame: Day 1, Hour 16, each product). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2016.
