Anterior vitreous detachment and retrolental material during cataract surgery: incidence and risk factors, with pathological evidence.

Spontaneous AVD is rare in phakic eyes. There was a marked increase in AVD during surgery, with retrolental material occurring in more than a third of cases. Higher CDE and longer total aspiration time were risk factors for AVD. Immunohistochemistry revealed that most of the retrolental materials were lens fragments.
