About this study

Official title: Myopia Control Combined PBM With Myopic Defocus Lens in Children: Double-blind RCT for 6 Month

To study the efficacy of myopi control with two methods: low lever red light and peripheral defocus spectacles with four groups and design with prospective, double-blind, randimized, and with control for 6 month.

Read the detailed description

myopic children with age from 6 ~13 years old. And refraction from -0.50D~-5.50D.

The red light is low lever laser therapy at wavelength of 650nm.

Being tested
PBM, Peripheral defocus spectacles, Single vision spectacles
Medical subject headings
Myopia, Degenerative

What participants receive

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

  • PBMDevice

    Also called Low lever light therapy; low intensity red light therapy; low lever laser therapy; repeated red light therapy

    PBM, is a low intensity red light at wavelength of 650nm; Peripheral defocus spectacels is a peripheral design glasseses for correct myopia and control myopia

  • Peripheral defocus spectaclesDevice

    Also called Myopic defocus spectacles for myopia control

    plus power design of many peripheral small lenses to achieve myopic defocus of the retina in the peripheral retina

  • Single vision spectaclesDevice

    Also called single vision glasseses for myopia correction lenses

    Distance vision correction with the single vision spectacles for the myopia correction methods (glasseses for myopia correction)

What is being measured

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

  1. axial length (mm)

    Axial length changes at follow-up of 6 month from baseline will be measured by IOLmaster 500 at the same site by the same examiner with the mean values of 5 times measurements at either time.

    Changes in axial length (mm) without cycloplegia are to be measured by IOLmaster(Carl Zeiss). Five measurements will be taken and then averaged.

    Measured: 6 month

  2. SE (Diopter, D)

    changes of cycloplegic spherical equivalent from baseline will be measured under cycloplegic refraction by autorefractor. Five measured by the same autorefractor are to be obtained for each eye.

    Measured: 6 month

Secondary outcomes (4)
  1. UCVA (logMar visual acuity record)

    Uncorrected visual acuity will be measured under 5-meter distance logMar Visual acuity chart without any aid (including the spectacles or contact lens) at baseline and at follow-up

    Measured: 6 month

  2. BCVA (logMar visual acuity record)

    Best corrected visual acuity will be measured under the same 5-meter distance logMar Visual acuity as the UCVA both at baseline and at follow-up.

    Measured: 6 month

  3. OCT

    Opitcal coherence tomography(OCT) record

    The marcular sturcture and image scanned by the optical coherent topography will be measured by linear scan at the marcular by the same Optical coherence tomography with the same examiner and the same instrument both at baseline and at follow-up

    Measured: 6-month

  4. SFCT (um)

    Sub-forveal choroidal thickness will be measured with the same software in the same Optical coherence tomography (OCT) at the location from the foveal center manually

    Measured: 6-month

Questions about this trial

What is this clinical trial studying?

A study testing PBM, Peripheral defocus spectacles and Single vision spectacles in people with Myopia, Progressive, run by Beijing Airdoc Technology Co., Ltd. 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 7 inclusion and 5 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: looking for participants now, as of the sponsor's last update on 9 Mar 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. Some participants in this study may receive a placebo. 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?

Contact Ying Li, MD, PHD (+8615162130727, 834582241@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

axial length (mm) (time frame: 6 month). 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 9 Mar 2023.
