Difficulties in data collection and management: Myopia control requires extensive data collection and management, including patient visual acuity, refractive measurements, and treatment effectiveness data. However, there are challenges in data collection and management, such as a lack of unified standards and guidelines, as well as insufficient tools for effective data management.

Imperfections in management and prediction models: Current models for managing and predicting myopia progression have significant uncertainties and cannot fully predict changes in myopia. 

Limited demand forecasting capabilities: There are limitations in accurately predicting the demand for different treatment modalities among myopia patients.
