ABSTRACT.Purpose: Posttraumatic partial or total iris defects often cause significant debilitating glare, photophobia, decreased vision and cosmetic problems. Currently, the best cosmetic results can be obtained with a customized silicone iris prosthesis. However, little is known about the functional results and the rate of complication if this type of iris prosthesis is implanted into severely traumatized eyes. The aim of this study is to analyse the functional and cosmetic outcomes as well as complications after Artificial Iris implantation. Methods: A consecutive series of 34 patients who received a customized silicone iris prosthesis after severe globe injury with total or sub-total iris loss was analysed retrospectively. Additionally, patients were interviewed regarding change in subjective complaints. Results: Median follow-up was 24 months (range 12.0-48.8). Mean visual acuity prior to Artificial Iris implantation was 1.1 logMAR (range 0.3-2.6). Five patients (15%) had pre-existing glaucoma and eight patients (24%) had pre-existing hypotony. Visual acuity 12 months after surgery was 1.4 logMAR (range 0.2-2.6). Complications included newly diagnosed glaucoma in three eyes (9%) and hypotony in three eyes (9%), persisting intraocular inflammation or macular oedema in seven patients (21%), and corneal endothelial decompensation requiring corneal transplantation in six patients (18%). Patients' satisfaction increased by reducing glare and enhanced cosmetic appearance. Conclusion: The customized silicone iris prosthesis is an individualized treatment approach with appealing cosmetic results. Therefore, especially traumatized eyes with highly different posttraumatic conditions could benefit. However, in some patients, the implantation of this device may cause an increase of intraocular pressure, corneal endothelial decompensation or persisting inflammation.

“…However, in the case of Magnus et al. (), mentioned earlier, no cataract development was observed despite the fact that 15 months after surgery, cataract surgery was performed according to the patient's wish. Furthermore, surgical techniques should be adjusted to the individual eye characteristics.…”

“…Contradictory reports exist regarding certain cosmetic types [ 23 ] of anterior-chamber Artificial Iris implantation in phakic eyes. [ 24 ] In addition, some patients are unhappy with the necessary indications [ 10 ] for aesthetic impairment (ie, AbCDefGh). Thus; we were motivated to make progress in this area of medicine.…”

“…[ 20 , 21 ] In this complex case of a perforating trauma with a corneal scar, an Artisan lens and a history of 9 surgeries (including primary repair, secondary IOL implantation, deep vitrectomies, and so on), a suturable Artificial Iris with fiber seemed more reliable than Artificial Iris without mesh. [ 10 , 20 , 21 , 24 , 25 ] In contrast, to provide an appropriately sized (approximately 12-mm or less) Artificial Iris according to the OCT, W-W, and S-S preoperative evaluations [ 16 ] and intraoperative measurements using a ruler, [ 26 ] cutting and resizing are recommended because the Artificial Iris is sized at 12.8 mm. Even smaller (11 mm) irises have also been recommended [ 20 , 21 ] for glaucoma prevention.…”

Purpose:To evaluate probable complications of ArtificialIris implantation with iris fixated intraocular lens.Method:Development of photophobia, glare, and psychological strain during face-to-face communication in a 23-year-old man with a widespread traumatic iris defect terminate to make a decision for performing implantation of an ArtificialIris (Humanoptics, Erlangen, Germany) under the remnant iris without removing the patient's existing Artisan lens.Results:Without any intraoperative or postoperative complications, the patient's visual acuity increased by 1 line, the endothelial cell loss was comparable with the cell loss associated with standard cataract surgery, and the anterior-chamber depth and anterior-chamber anatomy did not change. At the final follow-up examination, the mean intraocular pressure did not differ from baseline, and we achieved high level of patient satisfaction and subjective vision improvement. We discuss the particular importance of considering the patient's expectations, the appropriate measurements, ways to perfect color evaluation, and the types of ArtificialIris products.Conclusion:The implantation of the ArtificialIris in patients with aphakic iris-supported lenses (ie, pre-existing Artisan lenses) is a feasible approach and a useful option for patients with thin irises and iris hypoplasia who are at risk of subluxation or the dislocation of the posterior-chamber intraocular lens (PCIOL), and also those with sclerally fixed PCIOLs.

Patients with large iris defects not only suffer from functional disadvantages but also from aesthetic limitations. The aim of this study was to evaluate the aesthetic outcome of iris reconstruction using an artificial iris (AI). In this study, 82 eyes of 79 consecutive patients with mostly traumatic partial or total aniridia that underwent iris reconstruction surgery using a custom-made silicone AI (HumanOptics, Erlangen, Germany). Pre-and postoperative photographs of 66 patients were analysed subjectively and objectively. Subjective evaluation was based questionnaires. Objective evaluation included measurement of pupil centration and iris colour analysis. Averaged hues from iris areas were transferred to numerical values using the LAB-colour-system. Single parameters and overall difference value (ΔE) were compared between AI and remaining iris (RI), as well as AI and fellow eye iris (FI). Patients, eye doctors and laymen rated the overall aesthetic outcome with 8.9 ±1.4, 7.7 ±1.1 and 7.3 ±1.1 out of 10 points, respectively. Mean AI decentration was 0.35 ±0.24 mm. Better pupil centration correlated with a higher overall score for aesthetic outcome (p<0.05). The AI was on average 4.65 ±10 points brighter than RI and FI. Aniridia treatment using a custom-made artificial iris prosthesis offers a good aesthetic outcome. Pupil centration was a key factor that correlated with the amount of aesthetic satisfaction. The AI was on average slightly brighter than the RI and FI.
