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.

This video shows the use of trypan blue in penetrating keratoplasty, focusing on removal of stained viscoelastic from the anterior chamber with a Simcoe cannula. It explains that the dye makes residual viscoelastic visible, which might otherwise be left behind and pose a risk of raised intraocular pressure.
Key points
- Shows penetrating keratoplasty with trypan blue-stained viscoelastic
- Shows removal of the viscoelastic using a Simcoe cannula
- Explains residual viscoelastic can be seen because of the dye
- Notes retained viscoelastic is described as a risk factor for acute rise in intraocular pressure
