Stacked implantation of two prosthetic iris devices for patients with iris defects: A modified surgical technique

Iris pigment deficiency in patients with oculocutaneous albinism (OCA) often causes debilitating photophobia, which is routinely managed by sequential intracapsular insertion of two aniridia rings. A common concern of this technique is the risk of segment interdigitation, which can lead to intraoperative complications.

In this report, we describe a modified technique through which both rings were stacked together and inserted simultaneously in a 62-year-old male patient with oculocutaneous albinism and a mild cataract. The patient underwent bilateral phacoemulsification followed by implantation of two Morcher 50E aniridia rings simultaneously, prior to IOL implantation behind the implants within the capsular bag. Post-operatively, the patient's photophobia improved dramatically, and there were no post-operative complications.

Simultaneous insertion of two stacked aniridia rings prior to IOL implantation was a safe and successful alternative surgical method for the management of photophobia in patients with oculocutaneous albinism and cataracts.
