Following the creation of the "Big Bubble", this instrument is used to ensure that dissection is complete and extends out to the periphery.  It features a flattened spatulated tip which aids in any additional dissection that might be required.  The shaft of the instrument is triangular with a defined edge along each side as well as along the anterior surface.  The lateral edges can be used to cut through any incomplete areas of dissection.  Once dissection is completed, the stroma is safely bisected by running a disposable blade along the anterior edge while the flat posterior surface of of the instrument protects Descemet's membrane.
