Eligibility
Inclusion criteria
Inclusion criteria: 1.Age (calculated as of the date of screening): 6–12 years; 2.Eligible surgical type: unilateral or bilateral congenital cataract surgery with intraocular lens implantation; 3.Eligible refractive status: refractive error in any IOL eye: SE = +0.75 D, astigmatism > -2.00 D; 4.The child and family are willing to participate in treatment with low-concentration atropine eye drops;
Exclusion criteria
Exclusion criteria: 1.Prior use of low-dose (0.01%) atropine eye drops; 2.Current use or use within the past 3 months of any myopia-control intervention (e.g., myopia-control spectacle lenses such as DIMS/MiYOSMART, soft contact lenses designed for myopia control, or low-intensity single-wavelength red-light therapy); 3.Manifest strabismus; 4.Postoperative pupillary synechiae; 5.Known systemic disorders that may affect safety or participation (e.g., uncontrolled systemic autoimmune disease such as systemic lupus erythematosus; severe cardiovascular disease); diagnosis of glaucoma or glaucoma suspect (e.g., shallow anterior chamber, narrow angles); any contraindication to atropine, including known or suspected hypersensitivity to atropine, belladonna/tropane alkaloids, or formulation excipients. 6.Any other condition that, in the investigator’s judgment, makes the participant unsuitable for the study;
