Sample itemWhy is posterior capsule opacification not considered a recurrent cataract?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. The implanted lens remains clear while residual capsule becomes cloudy
After cataract surgery, residual lens epithelial cells can cloud the posterior capsule; the intraocular lens itself has not become a cataract.
Option by option
A. The implanted lens remains clear while residual capsule becomes cloudy (correct)
Correct: capsule clouding occurs behind an otherwise clear implant.
B. The retina detaches in every patient
Retinal detachment is a separate uncommon complication.
C. The cornea becomes acutely infected
Corneal infection has a different mechanism and presentation.
D. The natural lens regrows after extraction
The extracted natural lens does not regrow.
