Breakage of an intraocular lens (IOL) haptic during implantation is a rare complication of cataract surgery. We report here a case of a broken fragment of a trifocal IOL playing hide and seek and causing corneal edema repeatedly after an uneventful phacoemulsification and preloaded trifocal IOL (AT LISA tri 839MP) implantation. It was ultimately removed successfully and the patient achieved good vision. It is postulated that the broken piece of IOL migrated to and fro, from sulcus to anterior chamber. The breakage of IOL should also be kept in mind in the case of postoperative corneal edema when other causes have been ruled out.
