Exploratory Study on the Effect of SAT-001 on Choroidal Thickness in Pediatric Myopia Patients

Inclusion Criteria: 1. Children aged 4 to 12 2. Meet the following refractive criteria by cycloplegic refraction 1. Spherical equivalent refractive error (SER): -0.75 to less than -6.00 D in both eyes 2. Astigmatism of 2.50 D or less in both eyes 3. Best corrected visual acuity of 0.2 logMAR or better in each eye at the Screening Visit 4. Gestational age of 38 weeks or more at birth, or birth weight of 2,500g or more 5. Transparent ocular media 6. Participants and their legal guardians who agree to participate in the clinical trial and are willing to provide signed informed consent after receiving and understanding the explanation of the trial description (participants under 6 years old may mark their agreement after receiving full information and understanding) Exclusion Criteria: 1. History of eye diseases such as manifest strabismus, intermittent strabismus, amblyopia, and nystagmus (excluding strabismus that maintains binocular vision) 2. History of ocular surgery such as eyelid surgery, strabismus surgery, intraocular surgery, or refractive correction surgery (excluding simple double eyelid surgery) 3. Ocular abnormalities in cornea, lens, central retina, iris, ciliary body, etc., or presence of malignant tumors in the orbital area 4. History of multifocal lenses (e.g., progressive lenses), corneal refractive therapy lenses (Ortho-K, e.g., Dream lenses), rigid gas permeable (RGP) hard lenses, defocus incorporated multiple segments (DIMS) spectacle lenses (e.g., MyoSmart) within 30 days prior to Visit 2. 5. History of using myopia control agents (e.g., atropine) within 30 days prior to Visit 2 6. Currently participating in another clinical trial or who have participated in another clinical trial within 3 months prior to screening (Visit 1) 7. Inappropriate at the discretion of the investigator due to potential ethical concerns or the possibility of affecting the clinical trial results
