Eligibility
Sex/Gender
All
Age
4 Years to 12 Years
Inclusion criteria
Inclusion criteria: 1.Children aged 4 to 12 years, of either sex; 2. Cycloplegic refraction (after atropine-induced mydriasis) showing a refractive error of > +6.00 diopters (D) in both eyes, with astigmatism = 0.1 (decimal); 5. Ability to cooperate with visual acuity testing, cycloplegic refraction, ocular biometry, treatment procedures, and scheduled follow-up visits; 6. Written informed consent provided by the legal guardian prior to enrollment, with age-appropriate assent obtained from the child; children older than 8 years are required to sign a child-version informed consent form.
Exclusion criteria
Exclusion criteria: 1.Presence of organic ocular diseases, including corneal opacity, lens opacity or congenital cataract, retinal diseases, glaucoma or suspected elevated intraocular pressure, or severe ptosis affecting fixation; 2.Astigmatism > 2.50 D or large-angle manifest strabismus (corneal light reflex displaced beyond the pupillary margin); 3.History of ocular surgery or use of special ophthalmic medications; 4. Abnormal growth or development, such as endocrine disorders (e.g., short stature, precocious puberty), developmental or behavioral disorders that may interfere with cooperation; 5. Photosensitive epilepsy, a history of light-induced seizures, or any other safety concerns deemed by the investigator to make the participant unsuitable for inclusion.
