Clear Corneal Incision
Lens and Cataract, Surgery and Complications
- Currently the most popular entrance site for phacoemulsification cataract surgeries and intraocular lens implantations.
- These clear corneal wounds usually are self-sealing, and do not induce astigmatism as they heal.
- They have minimal risk of bleeding.
- May be complicated with Descemet's membrane stripping or tears.
- 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
