Iris on the Run

Dr. Christian Mayer demonstrates a tricky case of a “runaway” iris prosthesis in a 47-year-old patient who presented with severe glare caused by an oversize pupil. Two years prior, a blunt trauma injury was treated with vitrectomy and cataract surgery using a scleral-fixed IOL, but glare from the lingering iris defect reduced his vision to 20/200. Dr. Mayer uses a customized HumanOptics prosthesis to correct the functional and cosmetic issues. Unfortunately, 1 day after uneventful implantation, the prosthesis begins to drift off-center. The combination of a sulcus-embedded prosthesis and scleral-fixed IOL proves unstable, so Dr. Mayer sutures the margin of the prosthesis to the sclera. At 1-year follow-up, both patient and physician are pleased with the outcome.
