About

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.

Enrollment: 400 estimated patients
