#Types. Although many keratoprostheses have been developed, only four models are currently in commercial use: the Boston keratoprosthesis, Osteo-Odonto-Keratoprosthesis (OOKP), AlphaCor and the KeraKlear Artificial Cornea.
#Indications for non-penetrating keratoprostheses include the following: Keratoconus. Corneal Dystrophies. Corneal scars not related to active inflammation in the eye.
#Postoperative complications included retroprosthetic membrane [24 patients (65%)], increased intraocular pressure [14 patients (38%)], glaucoma progression [5 patients (13.5%)], and endophthalmitis [4 patients (11%)-3 who discontinued prophylactic antibiotics secondary to compliance].
