The trypan blue-stained viscoelastic is removed in its entirety
using a Simcoe cannula. A stream of Healonid GV can be seen flowing
into the cannula with some residual viscoelastic remaning, which is
subsequently removed. Without the dye, much of the viscoelastic
might have been left in the anterior... chamber – a risk factor
for an acute rise in intra ocular pressure.
