Clear Corneal Incision (click above image to load video)

Initially, a groove incision is created at the anterior edge of the vascular arcade
Using a diamond keratome, a CCI is made by depressing the posterior edge of the groove
While maintaining a parallel position to the surface of the cornea, the tip of the keratome is then advanced approximately 2 mm and turned posteriorly to perforate Descemet's membrane
The resultant 3-mm or slightly smaller incision is usually sufficient for proceeding emulsification and implanting a foldable intraocular lens
