Late-onset postoperative capsular bag distension syndrome
C. Perform YAG capsulotomy
Postoperative capsular bag distension syndrome (CBDS) describes a rare complication of cataract surgery with an incidence of 0.73%, in which opaque fluid accumulates in the retrolental space between the artificial lens and the capsular bag after cataract surgery with intraocular lens placement and intact posterior capsule.1,2 Different variants of CBDS have been classified, according to time of onset (intraoperative, early postoperative, and late postoperative)2 or underlying pathomechanisms (noncellular, inflammatory, fibrotic).1
The early-onset variant occurs between 1 day and 2 weeks postoperatively by unknown cause, whereas the late-onset or fibrotic variant has been described on average 3.8 years after uneventful cataract surgery3 and is expected to be caused by lens epithelial cell proliferation and pseudometaplasia.1,2 Large amounts of α and β crystalline have been isolated from the retrolental milky substance.4
