    A 45-year-old male developed advanced glaucomatous optic neuropathy 25 years after bilateral implantation of first-generation Fyodorov pIOLs.

  • 2

    The patient presented with elevated intraocular pressure (IOP) and severe visual impairment, necessitating surgical intervention for glaucoma management.

  • 3

    Micropulse trans-scleral cyclophotocoagulation (MP-TSCPC) successfully reduced IOP in the right eye, while the left eye was managed pharmacologically.

  • 4

    Long-term follow-up is crucial for patients with anterior chamber phakic IOLs due to risks of complications like glaucoma and cataract formation.

  • 5

    Electrophysiological examinations may aid in diagnosing complex cases of optic neuropathies, highlighting the need for early glaucoma detection.
