The Science behind the Tip
In pseudoexfoliation syndrome (PSX) and pseudoexfoliative glaucoma (PSG) progressive zonular damage frequently leads to in-the-bag IOL dislocation/subluxation even after seemingly uncomplicated cataract surgery. In PSX/PSG IOL dislocation typically appears several years after cataract surgery.
Therefore, eyes with late IOL dislocation are also often found to have pseudoexfoliation. Patients with pseudoexfoliation may be deemed to require regular assessment of IOL status in the long term and eyes with spontaneous late IOL dislocation need follow-up for the emergence of pseudoexfoliative glaucoma.
