Abstract Details


The implantation of the ArtificialIris, a custom-made silicone iris prosthesis, is a new treatment option for iris defects. Up to now, only a few case reports or smaller case series addressing artificial iris related complications have been published. The aim of this study was to investigate unexpected events and complications after implantation of the new artificial iris implant in a large sample of patients.


Prospective case series of fifty-one consecutive patients with iris defects presenting from 2011 to 2015 at the Department of Ophthalmology, Technical University Munich that underwent pupillary reconstruction with the new iris prosthesis.


The flexible iris prosthesis ArtificialIris (HumanOptics, Erlangen, Germany) used in this study is an innovative device in the surgical treatment of iris defects. Patients were examined before and after iris reconstruction by one surgeon. Change of visual acuity, number, type, severity and time point of unexpected events and complications as well as their management and the surgeonĀ“s learning curve were assessed.


Unexpected events and complications occurred in 13 artificial iris patients (25.5%), 38 procedures (74.5%) were uneventful. Mild complications included recurrent bleeding n=1 (2.0%), slight prosthesis dislocation n=1 (2.0%) and capsular fibrosis n=2 (3.9%). Moderate complications consisted of suture cutting through original iris n=1 (2.0%) and persitant ocular hypertension n=3 (5.9%). Severe complications that needed surgical intervention were dislocation of prosthesis n=3 (5.9%), glaucoma n=2 (3.9%), corneal decompensation n=5 (9.8%), cystoid macular edema n=3 (5.9%), retinal detachment n=1 (2.0%) and one iris prosthesis explantation (2.0%). Complication rate decreased from 83.3% in the first year, to 13.3% in the fourth year. 46.2% of all complications occurred within three months after surgery, 53.8% >3 months postoperatively.


The implantation of the artificial iris is a new and effective therapeutic option for the treatment of distinctive iris defects with a wide spectrum of potential peri- and postoperative unexpected events and complications. Complications can also be associated with the original disease or trauma that caused the iris defect. The complication rate decreases when the surgeon is more experienced.
