What is being measured

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

  1. Axial length

    To compare axial length growth of white European myopic children wearing Menicon Z Night orthokeratology contact lenses to a control group of distance, single-vision glasses and soft contact lens wearers. Measurements of axial length were taken with the Zeiss IOLMaster (Carl Zeiss Jena GmbH, Jena, Germany). Three separate measurements of axial length were recorded per subject and per visit, and a mean obtained.

    Measured: 11 years

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 (time frame: 11 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04806711, which also lists 2 linked publications.

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 Mar 2021.
