Eligibility
Inclusion criteria
Inclusion criteria: 1. Ages 4-16, regardless of gender; 2. Diagnosed with simple myopia or myopia combined with astigmatism, with specific criteria as follows: (1) Spherical equivalent between -0.50D and -8.00D (inclusive); (2) Astigmatism = 0.0 LogMAR; 3. Able to understand the purpose of the study, voluntarily participate, and sign the informed consent form either by the subject or their legal guardian, and able to complete follow-ups on time.
Exclusion criteria
Exclusion criteria: 1. Suffering from various eye diseases that require further treatment, including but not limited to: various acute or chronic eye inflammations, abnormal corneal sensitivity, keratoconus, corneal endothelial abnormalities, manifest strabismus, glaucoma, ocular hypertension (intraocular pressure >21 mmHg), eye tumors, pterygium, retinal detachment, or severe diseases of the ocular adnexa; 2. History of ophthalmic surgery, including corneal refractive surgery; 3. History of ocular trauma; 4. Currently using or planning to use during the study medications that may affect the wearing of rigid contact lenses, cause dry eye, affect vision or corneal curvature, or alter normal ocular physiology [such as immunosuppressants, glucocorticoids, intraocular pressure-lowering drugs, mydriatics (except for ophthalmic examination), miotics, etc.]; 5. Currently undergoing or previously received other myopia control interventions (including but not limited to orthokeratology lenses, multifocal soft contact lenses, myopia control spectacles, low-concentration atropine eye drops, etc.); 6. Other conditions deemed by the investigator to be unsuitable for inclusion.
