Who cannot join

What is being measured

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

  1. Axial Length (Axial Elongation)

    Axial Length was measured with the IOLMaster at baseline, and then every 6 months throughout the course of the study. Five measurements were collected for each eye at each visit and the average of the 5 measurements were used for the analysis. Higher values of axial elongation indicate worse vision.

    Measured: Baseline and every 6 months post-baseline up to 3 years

  2. Spherical Equivalent Refraction

    Spherical Equivalent Refraction was computed from the sphero-cylindrical refraction measured with an open-field auto refractor. The median of 3 repeated measurements, each of which was the average of 3 consecutive readings, was used for the analysis. Higher values of spherical refraction indicate progression in Myopia.

    Measured: Baseline and every 6 months post-baseline up to 3 years

Questions about this trial

What is this clinical trial studying?

A study testing Test Soft Contact Lens B, Test Soft Contact Lens C and Active Comparator in people with Myopia, run by Johnson & Johnson Vision Care, Inc. at 1 site in Hong Kong.

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 8 inclusion and 19 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 19 Jun 2018. 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 Hong Kong. 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 29 Jul 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?

Axial Length (Axial Elongation) (time frame: Baseline and every 6 months post-baseline up to 3 years). The study lists 2 primary outcomes in all. 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 19 Jun 2018.
