Abstract Details


To present a new surgical technique for treating corneal opacity and aniridia with aphakia and the results in a small consecutive case series.


Setting/Venue: 1. Department of Ophthalmology in Canton Solothurn, Switzerland. 2. Department of Ophthalmology, Eberhard-Karls University, Tuebingen, Germany.


A three-piece acrylic intraocular lens (IOL) was attached to a customized silicone iris prosthesis and fixed with three 10-0 polypropylene sutures in a knotless technique using Z-sutures after trephination of the recipient cornea. The medical records of all consecutive patients who had received a keratoplasty and an implantation of an artificial iris and IOL were reviewed.


Five eyes of five patients were included in the analysis. The mean age of the patients was 46.2 years and the mean follow-up was 24.6 months. The mean best-corrected visual acuity improved from 1.36 logMAR before surgery to 0.78 logMAR after surgery during the follow-up. At the last follow-up visit, the artificial iris-IOL complex was well centered with good positioning in all cases.


Management of post-traumatic aniridia combined with aphakia and corneal scars or graft failure by haptic fixation of a foldable IOL on an artificial iris combined with a simultaneous keratoplasty appears to be a promising approach, which allows to correct a complex lesion with a less traumatic and faster procedure.
