Five-year vision and prescription outcomes after infant congenital cataract surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective multicenter observational project that follows children who underwent cataract extraction before their first birthday to document visual and refractive development over five years. Participants will attend regular follow-up visits with measurements including best-corrected visual acuity, stereopsis, refractive error, and axial length growth. Children with acquired or traumatic cataracts, major ocular malformations, systemic syndromes affecting vision, or prior secondary surgeries are excluded to keep outcomes specific to early congenital cataract intervention. The data will be used to identify long-term trends and prognostic indicators to improve postoperative care and counseling.
