Brief description/objective

Purpose
The aim of this study is to analyze the outcome of various techniques for a custom-made iris prosthesis implantation as part of reconstructive anterior segment surgery following traumatic aniridia.

Methods
This retrospective interventional study was done for 6 eyes that received an artificial iris as secondary reconstructive measure for photophobia and unsatisfactory vision following initial globe repair. Different implantation techniques were employed. These included simple sulcus implantation, implantation of a composite (iris prosthesis with attached intraocular lens) implant, and combinations with phacoemulsification, vitrectomy, and penetrating keratoplasty.

Results
In all cases, the artificial iris was implanted successfully. In the follow-up period (1-48 months), postoperative complications included rhegmatogenous retinal detachment, prolonged intraocular inflammation, and corneal transplant decompensation due to graft rejection. There was no case of secondary glaucoma. Complications could be managed successfully. All patients showed improved best-corrected visual acuity and were satisfied with functional and cosmetic results.

Conclusion
This case series highlights the different implantation techniques for reconstruction of the anterior segment after ocular trauma. The versatility of the custom-made iris implant accounts for a wide range of applications and the foldable material reduces the need for large incisions in the already traumatized eye.
