PURPOSE: To describe a novel technique for cataract surgery in patients with iris coloboma.
METHODS: The technique involves 1) creation of an inferiorly displaced capsulorrhexis and 2) amputation of one intraocular lens (IOL) haptic, thus allowing for controlled IOL decentration in the direction of an inferior iris defect.
RESULTS: We report favorable outcomes in two eyes (one patient) where eccentric capsulorrhexis and haptic amputation were employed during one-piece IOL repositioning in one eye and cataract surgery with three-piece IOL implantation in the contralateral eye.
CONCLUSION: In coloboma patients who are asymptomatic from their iris defect and do not have a cosmetic desire for repair, eccentric capsulorrhexis and IOL haptic amputation is a viable surgical option that allows for the preservation of a clear visual axis without the need for iris repair.
