Investigating the Effect of Using Myopia Prediction Algorithm on Myopia Children
August 6, 2019 updated by: Haotian Lin, Sun Yat-sen University
Investigating the Effect of Using Myopia Prediction Algorithm on Myopia Children's Eye Refraction in China: a Multi-center Randomized Control Trial
In this study, the investigators aim to perform a prospective, randomized controlled study to compare the myopia development between myopia children using myopia prediction algorithm and myopia children without using myopia prediction algorithm

Intervention / Treatment
Detailed Description
We propose to enroll myopia children aged 8-10 in China.
Children will be given examinations of visual acuity, eye refraction and biometrics, and be assigned to two groups: participants in group A use myopia prediction algorithm to predict myopia development, while in Group B, the participants do not use myopia prediction algorithm to predict myopia development.
The visual acuity, eye refraction and biometrics will be investigated over the one-year follow-up period, aiming at comparison of actual myopia development between the two groups

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Not using myopia prediction algorithm
After examination of visual acuity, eye refraction and biometrics, the examination results are shown to the children.

Experimental: Using myopia prediction algorithm
After examination of visual acuity, eye refraction and biometrics, the examination results are shown to the children.
Meanwhile, myopia prediction algorithm will be used to predict SER at 3 years.
|
Candidate predictors mainly includes age at examination, SER, and annual progression rate.
Using these predictors, the algorithm will be used to predict SER at 3 years.
