Age
4 Years to 12 Years
Inclusion criteria
Inclusion criteria: 1. Ages 4-12, no gender restrictions; 2. Previously diagnosed with congenital ectopia lentis; 3. Undergone bilateral lens extraction combined with intraocular lens suspension surgery, with the second eye within 1 month ± 1 week after surgery; 4. Best-corrected visual acuity in both eyes is no less than 20/200 but below the normal level for the corresponding age: for 4-year-old patients, best-corrected visual acuity in both eyes is no higher than 20/40; for patients aged 5 years and above, best-corrected visual acuity in both eyes is no higher than 20/30. 5. Patients and parents sign a written informed consent form.
Exclusion criteria
Exclusion criteria: 1.Previous history of ocular trauma or ocular surgery; 2. Unable to cooperate with treatment, examination, follow-up assessment. 3. Cases requiring urgent surgical intervention include recurrent lens dislocation, severe cataracts (dense, located along the visual axis, with a diameter of >3 mm and affecting central vision), secondary glaucoma, corneal endothelial cell decompensation, or retinal detachment. 4. Diplopia in either eye; 5. History of neurological disorders (such as photosensitive epilepsy); 6. Did not participate in other clinical trials that may affect the results of this trial after surgery. 7. No use of local/systemic medications that may cause visual impairment or other visual treatments (such as atropine eye drop suppression therapy, occlusion therapy, digital therapy, Bangerter filters, optical suppression, VR training, etc.) other than refractive correction in the past three months.
