Inclusion criteria
Inclusion criteria: 1. Aged between 3 and 18 years (inclusive); 2. Patients who had at least one outpatient visit with a complete set of the following data: Non-cycloplegic or cycloplegic subjective refraction/retinoscopy; IOL-Master biometry data; Spectacle dispensing records within 2 weeks; 3. Patients with at least two visits containing complete subjective refraction (or retinoscopy) and axial length data, with a follow-up interval of >= 6 months between visits.(for the retrospective cohort).
Exclusion criteria
Exclusion criteria: 1.Presence of organic eye diseases: Including but not limited to congenital cataract, glaucoma, keratoconus, retinopathy, nystagmus, and retinal detachment. 2.History of ocular surgery: Including but not limited to strabismus surgery, congenital cataract surgery. 3.Interference from medications or interventions: History of wearing orthokeratology (Ortho-K) lenses (due to induced changes in corneal morphology or axial length). History of using other myopia control interventions (e.g., defocus spectacles, defocus soft contact lenses, low-concentration atropine, etc.). 4.Unreliable biometric data: Low signal-to-noise ratio (SNR) or unreliable data quality in IOL-Master measurements (e.g., standard deviation [SD] of axial length measurement > 0.05 mm). 5.Systemic diseases affecting ocular development (Such as Marfan syndrome, albinism, etc).
