Used to inject air through the inter corneal tunnel created by the Sarnicola DALK Spatula to form the Big Bubble. Designed so the air insufflates from top to bottom in a very deep plane and increases the percentage of Big Bubble formation. Also used to inject viscoelastic in the space between the stroma and the DM after Big Bubble formation and to create an Air-Visco Bubble if a successful Big Bubble was not achieved. This cannula is very smooth so as to avoid penetrating the DM.
