Congenital membranous cataract associated with persistent fetal vasculature.

A 15-year-old boy underwent phacoemulsification for a membranous cataract during which the presence of anterior persistent hyaloid artery and elongated ciliary processes were discovered. A posterior capsulorhexis was performed and the anterior part of the persistent hyaloid artery stalk was resected together with the posterior capsule. A foldable intraocular lens was implanted and the optic was captured in the posterior capsulorhexis margin. This is an unusual case of congenital membranous cataract associated with malformations of persistent fetal vasculature and elongated ciliary processes.
