Abstract Details

Purpose:

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

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
