Eligible patients must demonstrate inadequate control of myopia progression, defined as an axial length increase of >=0.3 mm per year or a spherical equivalent refraction (SER) progression of >=0.5 D per year; 3. Best-corrected visual acuity (BCVA): 20/20 or better; 4. Treatment: Data from patients who have received or are planning to receive red light therapy as a strategy for myopia management.
