What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Success Rate of Lens Centration After 7 ± 2 Days of Wear

    Lens centration (the centration of the contact lens over the cornea) was rated by the investigator during slit lamp examination using a 5-point scale (0=optimal, 4=severe decentration). Success was defined as the percentage of subjects whose lens centration was rated as "optimal" or "slight decentration. One eye (study eye) was analyzed.

    Measured: Day 7, each product

Questions about this trial

What is this clinical trial studying?

A study testing Delefilcon A contact lenses and Narafilcon A contact lenses in people with Myopia and Refractive Error, run by Alcon Research at 1 site in Japan.

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 9 inclusion and 10 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 29 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

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 28 Dec 2015). 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?

Success Rate of Lens Centration After 7 ± 2 Days of Wear (time frame: Day 7, 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 29 Jan 2016.
