Pars plana vitrectomy combined with penetrating keratoplasty.
Pars plana vitrectomy combined with keratoplasty using a temporary keratoprosthesis is a surgical procedure used in patients with vitreoretinal disorders complicated by severe corneal opacification. Temporary keratoprostheses include the Landers type and Eckardt type. Use of the Eckardt temporary keratoprosthesis is superior because of a wider optical diameter and easier visualization of the peripheral fundus. However, one problem with this procedure is that many patients develop postoperative rejection and loss of transparency of the corneal graft. To maintain good transparency of the corneal graft after surgery, vitrectomy must be minimally invasive and postoperative anti-inflammation must be ensured.
