What is it?
A dropped fragment causes inflammation, raised eye pressure and swelling of the retina if left. Vitrectomy removes it, and the lens is placed or fixed in a stable position in the same sitting when possible.
A dislocated IOL years after surgery can also be repositioned or exchanged.
Symptoms
- Poor vision after cataract surgery
- Pain and redness that do not settle
- Seeing the edge of the lens or double images
Risk factors and causes
- Complicated cataract surgery
- Weak lens support (pseudoexfoliation, injury)
Usually within 1 to 2 weeks of the cataract operation.
