Flexible Artificial Iris Implantation

To evaluate the outcomes and complications after artificial iris implantation in patients with aniridia

Retrospective observational case series

This was a retrospective observational case series. We collected 8 eyes of 6 patients from September 2021 to January 2024 in Taipei Municipal Wanfang Hospital. All operations were performed by a single ophthalmologist. The main outcomes included postoperative visual acuity, intraocular pressure, and complications after the operation.

6 patients with a mean age of 38.6 years were included in this study. Artificial iris dislocation was noted in 2 of the patients during follow-up. Visual acuity increased from a baseline mean 0.91 logMAR (SD ±0.6) to 0.58 logMAR (SD ±0.4) after artificial iris implantation. Indications include congenital aniridia, traumatic aniridia, and Urrets-Zavalia Syndrome. The results showed no differences between preoperative and postoperative intraocular pressure.

Artificial iris implantation in our hospital showed satisfactory results in most patients. However, it is worth noting that 2 patients experienced artificial iris dislocation, and artificial iris reposition was needed. Overall, postoperative assessments indicated enhancements in both visual acuity and cosmetic appearance.
