When the cortex gets opaque, it makes the visualization poor because it blocks the red reflex from retro-illumination. Sometimes, the cortex starts out looking reasonably translucent, but when the fluid waves of the hydro-dissection pass, they can whip up the cortex and turn it opaque in seconds. This happens during the cataract surgery video presented here: the cortex becomes so fluffy and opaque that it blocks most of the retro-illumination. How should we proceed?
