Keratoprosthesis is a chance for all patients who have bilateral visual loss due to corneal pathology so serious and extensive that it cannot be removed by graft transplantation. This problem mainly affects less developed countries. The eyesight of these patients could return to normal if corneal transplants were practiced and keratoprosthesis were widely available. Keratoplasty makes great progress and gets better and better results. The future will show whether there will be more reliable and biologically integrated keratoprosthesis, with low risk of complications.
