About this study

Objective: To study the effectiveness and safety of low-intensity single wavelength red light in controlling high myopia in children and adolescents.

Methods: Subject population: Children aged 3-16 years who have high myopia. Sample size: 190 subjects were planned to be enrolled and assigned to the test or control group in a 1:1 ratio.

Read the detailed description

Design: The trial was a randomized, controlled, multicenter clinical trial. A total of 190 children aged 3-16 years with high myopia were selected and divided into 95 cases in the test group and 95 cases in the control group. The test group was treated with the Eyesing Instrument developed by Suzhou Industrial Park Zoguan Medical Equipment Co. and conventional optometry. The safety and efficacy of the low-energy laser device in the test group were evaluated by comparing the changes in myopia between the two groups during the observation period. Subjects were screened after signing the informed consent form (performed as early as 7 days before the randomization), and the examination used for screening could use the results of eye examinations performed within 1 week at our hospital, and they were enrolled after confirming that they met the inclusion criteria. On the same day, the grouping was done by randomization, and the glasses were prescribed or the glasses were prescribed in combination with the device according to the grouping results. Visits were performed at 30± 14 days, 90± 14 days, 180± 14 days, 270± 14 days, and 365± 14 days

Who may be eligible to take part?

The sponsor lists 3 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 18 Nov 2023. 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 China. 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?

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 changes (time frame: 30± 14 days, 90± 14 days, 180± 14 days, 270± 14 days, and 365± 14 days). 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 NCT05184621, which also lists 5 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 18 Nov 2023.
