Clear Corneal Incision

Clear Corneal Incision 

  • 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
