All

Inclusion criteria

Inclusion criteria: Age between 6 and 15 years old Spherical equivalent refraction between -8.0 and -1.0 D in both eyes under cycloplegic objective refraction Astigmatism of 2.0 D or less Anisometropia of 1.5 D or less

Exclusion criteria

Exclusion criteria: Patients who have ocular diseases other than refractive error that may affect visual acuity or refractive status, Patients who have any eye with best-corrected visual acuity (BCVA) less than 1.0 History of intraocular or refractive surgery Patients in whom cycloplegic examination is difficult to perform due to drug allergies or other reasons Patients deemed inappropriate for inclusion in this study by the principal investigator or sub-investigator Patients with prior experience of any of the following myopia progression control treatments within the specified periods listed below: 0.01% atropine eye drops: within the past 1 month 0.025% atropine eye drops: within the past 3 months Multifocal soft contact lenses (SCL): within the past 1 month Patients with prior experience of myopia progression control treatments other than those listed above
