A 30-year-old male asked:

Why do post-cataract surgery retinal detachments occur? is there some retinal pulling involved from posterior vitreous detachment (pvd)?

Destabilization: The natural lens and its supports stabilize the front of the eye and vitreous. Removal of the thick natural lens and substitution with a thin artificial lens, increases the chance for the vitreous to move in ways that can destabilize the attachments of the vitreous over the retina. If there are weak places, this can increase the chance of detachment, even in the best of cataract surgeries.

Uncommon: Retinal detachment after modern uncomplicated cataract surgery is rare. It is not related the the phenomenon of pvd. It is suspected that manipulation of instruments in the eye and the forces they generate can cause an already weakened or predisposed retina to detach during the post operative period.
