Brief summary

The global rise in myopia, particularly among children and adolescents in China, underscores the inadequacy of current prevention strategies, indicating that conventional screening and education alone are insufficient to curb the prevalence. Integrating personalized myopia prediction into routine care may enhance risk awareness, promote proactive prevention, and improve adherence to medical advice, ultimately reducing the future burden of high myopia. A myopia prediction system based on artificial intelligence was previously developed, accurately predicting future high myopia risk using efficient, robust, and easily accessible predictive factors, including age, spherical equivalent, and the annual progression of spherical equivalent. This study aims to conduct a prospective, one-year, cluster randomized controlled clinical trial to investigate the effectiveness of this prediction system in preventing and controlling myopia in school-aged children.

Interventions

OTHERFeedback on Predicted High Myopia Risk at Age 18 Using the Myopia Prediction System

At baseline and six months, participants will be provided with the results of their predicted risk of high myopia at age 18 based on the myopia prediction system.

OTHERFeedback on Ophthalmic Examinations

At baseline and six months, participants will be provided with the results of their ophthalmic examinations.

Inclusion criteria

* The participant and their guardian voluntarily signed the informed consent form * Has the record of eye refraction examination in the past year * Aged 9 to 11 years, regardless of gender

Exclusion criteria

* High myopia(spherical equivalent ≤ -6.00 D) * Ocular diseases other than myopia (e.g., strabismus, amblyopia, congenital cataract, juvenile glaucoma, retinal diseases). * Systemic diseases that may affect vision or visual development (e.g., diabetes or other endocrine disorders, cardiovascular or respiratory diseases, Down syndrome)

Design outcomes

Primary

MeasureTime frameDescription
Proportion of Individuals Predicted to Develop High Myopia at Age 18 by the Myopia Prediction System1 yearAt the end of the one-year study, the Myopia Prediction System will be used to predict whether students will develop high myopia at age 18 in both the intervention and control groups. The Proportion of Individuals Predicted to Develop High Myopia at Age 18 by the Myopia Prediction System is calculated as the total number of students in each group predicted to develop high myopia by age 18, divided by the total number of students in the respective group.
Cumulative Clinical Visit Rate for Myopia Prevention and ControlWithin 3 months after each interventionThe Cumulative Clinical Visit Rate Proportion of Clinical Visits for Myopia Prevention and Control is the proportion of students in the intervention or control group who visited a hospital or clinic for myopia-related care (e.g., refractive exams and treatment) at least once within three months of either intervention. It is calculated as the number of students in each group who attended a clinical visit within three months of at least one intervention, divided by the total number of students in the respective group.

Secondary

MeasureTime frameDescription
Myopia Incidence Rate1 year1-year myopia incidence rate = number of new myopia cases within one year / number of non-myopic cases at baseline \* 100%
Changes in Spherical Equivalent1 yearChange in spherical equivalent (non-cycloplegic autorefraction) will be calculated
Screen Time1 yearDaily usage time of electronic devices (computer/smartphone/tablet computer) will be calculated
Outdoor Activity Time1 yearDaily outdoor activity time will be calculated
