Objective:

To report a case of advanced glaucomatous optic neuropathy decades after pIOL implantation and to discuss management strategies, highlighting the importance of long-term monitoring.

Key Findings:
  • The patient had advanced glaucomatous optic neuropathy with high IOP and cataract formation, indicating severe complications from pIOLs.
  • MP-TSCPC successfully reduced IOP in the right eye from 23 mmHg to 16 mmHg, showcasing effective management.
  • Phakic intraocular lenses can lead to long-term complications such as glaucoma and cataracts, necessitating vigilant monitoring.
Interpretation:

Long-term follow-up is crucial for patients with pIOLs to prevent severe complications like glaucoma, which can lead to irreversible optic nerve damage, emphasizing the need for regular assessments.

Limitations:
  • The patient lacked medical documentation and prior ophthalmological evaluations, complicating the assessment of his condition.
  • The case highlights challenges in diagnosing and managing late-onset complications of early-generation pIOLs, underscoring the need for awareness among practitioners.
Conclusion:

Early detection and management of glaucoma in patients with pIOLs are vital to prevent significant visual impairment, reinforcing the importance of routine follow-ups.
