Trial summary

Background: Myopia refers to the pathological state in which the external parallel light enters the eye and focuses in front of the retina, resulting in the inability to clearly image on the retina. The number of myopia in China ranks first in the world. Read more about this study

About this study

Official title: Efficacy and Safety of Defocusing Frame Glasses With Artificial Intelligence in Children and Adolescents Controlling Myopia Progression: A Multicenter, Randomized, Parallel-Controlled Clinical Trial

Background: Myopia refers to the pathological state in which the external parallel light enters the eye and focuses in front of the retina, resulting in the inability to clearly image on the retina. The number of myopia in China ranks first in the world. According to statistics from the National Health and Health Commission, the myopia rate of children and adolescents nationwide in 2020 will be as high as 52.7%. High myopia often leads to permanent visual impairment and even blindness. Retinopathy complicated by high myopia has become the first irreversible blinding eye disease in Shanghai and other regions. The problem is severe. Therefore, it is necessary to actively seek effective myopia treatment and correction methods to slow down the progression of myopia and the excessive extension of the eye axis and reduce the occurrence of complications.

Objective: On the basis of previous research, this study put forward the hypothesis that if behavior management (including outdoor light exposure and close-range eye-use behavior) can be strengthened in children with myopia wearing defocusing frame glasses, it is possible to achieve more effective myopia control effect, thereby not only ensuring safety also effectiveness. A randomized controlled clinical trial is conducted to evaluate the efficacy and safety of defocusing frame glasses with artificial intelligence in controlling myopia progression in children and adolescents.

Intervention: Group 1 ( AI defocusing frame glasses group), Group 2 ( Ordinary defocusing frame glasses group). The study period will be 2 years and each participant will be followed up every six month.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AI defocusing frame glassesDevice

    AI defocusing frame glasses have the function of eye behavior management, which can delay the progression of myopia through scientific management of eye behavior including outdoor light exposure (≥2 hours/day), duration of continuous close eye use (30 seconds rest every 30 minutes) and close eye distance (one punch, one foot and one inch), etc.

Questions about this trial

What is this clinical trial studying?

A study testing AI defocusing frame glasses in people with Myopia, run by Shanghai Eye Disease Prevention and Treatment Center at 1 site in China.

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 4 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 4 Oct 2022. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Haidong Zou, MD (021-53555032, zouhaidong@sjtu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

changes of spherical equivalent (time frame: at least 2 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 NCT05532774, which also lists 1 linked publication.

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 4 Oct 2022.
