Cortical wash sometimes can become a very painful task dragging along too much time
This often happens when the surgeon was unable to achieve cortical-cleaving hydrodissection
How can you differentiate a cortical-cleaving hydrodissection from a non-cleaving one?
You can do so by carefully observing the fluid wave front.
A cortical-cleaving hydrodissection wave traverses far more slowly and its leading font is serrated rather than smooth and convex
