Non-arteritic anterior ischemic optic neuropathy following flanged-scleral-fixated intraocular lens surgery in the case of traumatic cataract

We present a rare case of non-arteritic anterior ischemic optic neuropathy (NAION) following flanged-scleral-fixated intraocular lens (SFIOL) implantation in a middle-aged patient with traumatic cataract and no systemic risk factors. Postoperative complications included hypotony, choroidal detachment (CD), and persistent optic disc edema. Visual field analysis revealed an inferior altitudinal defect, confirming the diagnosis of NAION. Systemic and neuroimaging evaluations were unremarkable. This case highlights a possible association between postoperative hypotony and optic nerve ischemia following complex intraocular surgery. It emphasizes the importance of close postoperative monitoring of optic nerve health, especially in trauma-related cases requiring secondary IOL fixation.
