Clinical Trial Summary

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

Description:

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.
