Tip of the Month
Tip of the month - Late in-the-bag intraocular lens dislocation several years after uncomplicated cataract surgery is relatively common in pseudoexfoliation
Late in-the-bag intraocular lens dislocation several years after uncomplicated cataract surgery is relatively common in pseudoexfoliation

Publishing date: March 2020


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.
