    Abstract:
    PURPOSE: To examine complications, visual outcomes, photic patient-reported symptoms, corneal morphology, IOL tilt, and intraocular pressure after implantation of an intraocular lens (IOL) and iris prosthesis (IP) following iridocyclectomy. METHODS: Patients with previous iridocyclectomy treated with an IOL and IP at the Copenhagen University Hospital Rigshospitalet between 2007 and 2018 were included in this national retrospective non-comparative case series. The assessment encompassed BCVA, PRO questionnaire, corneal topography, and anterior segment OCT. RESULTS: 45 patients were included. Eight of 45 patients were previously treated with ruthenium-106 brachytherapy in conjunction with iridocyclectomy. Six of 45 patients developed endothelial dysfunction four of whom had received ruthenium-106 brachytherapy. Five of 45 patients had subluxation of the IOL/IP complex due to incomplete zonula apparatus. BCVA improved for all patients after lens surgery. 26 patients participated in the invited follow-up examination. 19 of 26 (73%) reported none or mild photic symptoms after IP instalment. Five (19%) reported ongoing severe photic symptoms. The corneal astigmatism significantly increased after iridocyclectomy but did not change after lens surgery. CONCLUSIONS: Implantation of an IOL and IP is a safe procedure, alleviating photic symptoms in most patients. It comes with higher risk of complications due to a more demanding procedure and larger surgical traumas from previous treatments. Ruthenium-106 brachytherapy increases the complication risk. Corneal astigmatism is induced by iridocyclectomy but does not change after lens surgery.
