What is being measured
The primary outcome is the main question the study is designed to answer.
High Contrast Time-Controlled Visual Acuity (TCVA) (VA Unit) Post-Exposure to Reduced Humidity at Day 10
High contrast TCVA was assessed after 3 hours exposure to reduced humidity environment. TCVA test was performed at 4 meters under high illumination (90%) using a Landolt ring test. For each acuity level, a series of single rings with gaps in one of four directions was presented and the percentage of correctly identified rings constituted the score. TCVA was measured in VA units and a higher TCVA value indicates an improvement in visual acuity. Both eyes contributed to the analysis.
Measured: Day 10, each product
Secondary outcomes (1)
High Contrast TCVA (VA Unit) Pre-Exposure to Reduced Humidity at Day 10
High contrast TCVA was assessed after 3 hours exposure to normal environment and prior to exposure to reduced humidity environment. Both eyes contributed to the analysis.
Measured: Day 10, each product

Questions about this trial
What is this clinical trial studying?
A study testing Stenfilcon A contact lenses and Narafilcon 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 5 inclusion and 5 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 5 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?
High Contrast Time-Controlled Visual Acuity (TCVA) (VA Unit) Post-Exposure to Reduced Humidity at Day 10 (time frame: Day 10, 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 5 Dec 2016.
