Study summary

Pre-myopia refers to a condition in which children have not yet developed myopia but exhibit insufficient hyperopic reserve (≤ +0.75 D). This is particularly relevant for young children aged 6 years and under; if their hyperopic reserve is depleted prematurely and they progress into the pre-myopia stage, the likelihood of developing myopia or even high myopia in the future becomes extremely high. Therefore, this study plans to conduct a parallel-design, open-label, single-center randomized controlled clinical trial to evaluate the efficacy and safety of artificial intelligence-assisted defocus incorporated multiple segments (DIMS) based spectacle lens in preventing and controlling myopia in pre-myopic children aged 3 to 6 years.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age between 3 and 6 years (inclusive), regardless of gender or ethnicity.
  • Cycloplegic spherical equivalent refraction (SER) of the worse eye > -0.50 D and ≤ +0.75 D, absolute cylindrical power ≤ 1.0 D, anisometropia ≤ 1.5 D.
  • Best corrected monocular distance high contrast VA ≥ 0.5 for ages 3-5; ≥ 0.7 for age 6.
  • At least one parent with SER ≤-3.00D

Exclusion criteria

Exclusion Criteria:

  • Individuals with any ocular or systemic diseases that may affect vision and refractive development (e.g., keratoconus, abnormalities in lens shape or position, Marfan syndrome, retinopathy of prematurity, etc.).
  • Individuals with known allergies or to cycloplegic agents.
  • Previous use of myopia management treatment (spectacles, atropine; CLs).
  • Individuals with binocular vision abnormalities: manifest strabismus, monocular suppression, abnormal fusion function, or impaired stereopsis.
  • Individuals unable to cooperate with examinations or communicate.
  • Any other conditions deemed by the investigator as unsuitable for participation in the study.

Study arms

  • Experimental
    Intervention group

    Wear AI-assisted DIMS-based spectacle lens (at least 10 hours a day), as well as smartwatches

    Device: Artificial Intelligence Assisted DIMS based Spectacle Lens · Device: Smartwatches

  • Other
    Control group

    Wear smartwatches

    Device: Smartwatches

Interventions

  • DeviceArtificial Intelligence Assisted DIMS based Spectacle Lens

    The AI-DIMS defocus spectacle frame, featuring DIMS-based lenses and an intelligent AI frame, is designed to be worn for at least 10 hours per day. The frame automatically tracks and records wearing duration parameters.

  • DeviceSmartwatches

    Inserted prompt system of the smartwatches can remind the users to go outside. Inserted sensors can record outdoor parameters such as outdoor time, light intensity, activity pattern, etc.
