Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the incidence of glaucoma-related adverse events of in-the-bag versus ciliary-sulcus-fixed secondary intraocular lens (IOL) implantation in pediatric aphakia

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Treatment of pediatric cataract, one of the leading causes of childhood blindness globally, remains challenging because of extremely high incidence of glaucoma-related adverse events (AEs) after IOL implantation. The investigators aim to compare the incidence of glaucoma-related AEs of in-the-bag versus ciliary-sulcus-fixed secondary intraocular lens (IOL) implantation in pediatric aphakia.
