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 malfor- mations of persistent fetal vasculature and elongated ciliary processes.
