A new temporary keratoprosthesis for pars plana vitrectomy

Abstract

Using a new temporary keratoprosthesis in an eye with an opaque cornea and a proliferative vitreoretinopathy, a pars plana vitrectomy combined with a silicone oil injection was successfully performed. The new keratoprosthesis is made of silicone rubber and is fixed to the threphined corneal bed with four 10-0 nylon sutures. It permits an excellent view of the intraocular structures and allows vitreoretinal surgery even in the region of the pars plana and vitreous base. It is replaced by a corneal graft at the end of the vitrectomy.
