Five-Year Visual Function and Refractive Outcomes After Congenital Cataract Surgery

Five-Year Visual Function and Refractive Outcomes After Congenital Cataract Surgery: A Multicenter Observational Cohort Study

This prospective multicenter observational study aims to evaluate the 5-year visual function and refractive outcomes in children undergoing surgery for congenital cataract. Key outcomes include best-corrected visual acuity, stereopsis, refractive error, and axial length growth. The study will help identify long-term trends and prognostic indicators after early cataract intervention in pediatric patients.

Inclusion Criteria:

• Diagnosis of congenital cataract
• Underwent cataract extraction before 1 year of age
• Available for regular follow-up for at least 5 years postoperatively
• Written informed consent from legal guardian

Exclusion Criteria:

• Acquired cataract or traumatic origin
• Associated ocular malformations (e.g., microphthalmia, coloboma)
• Systemic syndromes affecting vision (e.g., Down syndrome)
• History of secondary surgery affecting visual outcome
