About this study

Official title: Safety and Efficacy of Blue Star MAX-5 Lenses in Mvopia Control: A Randomized Controlled Clinical Trial

The goal of this randomised controlled clinical trial is to compare the effects of a new type of concentric columnar microstructure lens and single-vision spectacle lenses on myopia progression in Chinese children aged 8-11 years with refractive error ranging from -0.50D to -6.00D. Participants will wear spectacles and receive follow-up examinations every half year.

What participants receive

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

  • Blue star MAX-5 spectacle lensDevice

    The children in the experimental group will wear Blue star MAX-5 spectacle lens and receive follow-up examinations every half year.

  • Single-vision spectacle lensDevice

    The children in the single-vision lenses group will wear single-vision spectacle lens and receive follow-up examinations every half year.

What is being measured

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

  1. Changes of spherical equivalent refraction (SER) at two years

    The difference of SER (Diopter) at two years compared with baseline SER. SER will be measured after cycloplegia.

    Measured: 2 years

Secondary outcomes (3)
  1. Changes of axial length (AL) at two years

    The difference of AL (mm) at two years compared with baseline AL. AL will be measured by IOLMaster-700.

    Measured: 2 years

  2. Visual scale score at two years

    Visual scale score measured by the Chinese version of the pediatric refractive error profile2 (PREP2) is scaled from 0 (poor quality of life) to 100 (good quality of life).

    Measured: 2 years

  3. Incidence of adverse event during study period

    Adverse event is a comprehensive qualitative outcome measure that will be evaluated based on the participants' symptoms and signs, intraocular pressure, slit lamp and fundus examinations, as well as lens and frame damage. The evaluation will be conducted every six months according to the predetermined definition of abnormalities in the above examinations.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Blue star MAX-5 spectacle lens and Single-vision spectacle lens in people with Myopia, Progressive, run by Zhongshan Ophthalmic Center, Sun Yat-sen University 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 5 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: under way, not looking for participants, as of the sponsor's last update on 12 Mar 2026. 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?

This study is still under way. Results are not available in the source record yet.

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?

Changes of spherical equivalent refraction (SER) at two years (time frame: 2 years). 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 12 Mar 2026.
