What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Ex-vivo Cholesterol Deposits After 30 Days of Wear
The contact lens (right eye) was removed and stored dry and frozen until analysis. Total cholesterol deposits (cholesterol and cholesterol esters) were extracted from the lens and measured in micrograms. Lower deposits indicate increased lens performance. Study originally intended to analyze 36 lenses per arm, but actual number of lenses analyzed was less due to measurement error.
Measured: Day 30, each product

Questions about this trial
What is this clinical trial studying?
A study testing Lotrafilcon B contact lenses, Samfilcon A contact lenses and Hydrogen peroxide solution 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 5 inclusion and 6 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 28 Dec 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 19 Oct 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?
Mean Ex-vivo Cholesterol Deposits After 30 Days of Wear (time frame: Day 30, 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 28 Dec 2016.
