Unlabelled:
Cataract surgeons are sometimes challenged with a patient who has an unstable anterior chamber intraocular lens (AC IOL). Over time, an unstable AC IOL can lead to significant complications. This problem is most often addressed with an IOL exchange using an appropriately sized AC IOL or a posterior chamber IOL with iris or scleral fixation. We present a technique of 2-point iris fixation of unstable AC IOLs as a simpler and less traumatic alternative.
