Keratoprosthetics implantation entails removing the cornea to its full thickness and replacing it with an artificial cornea. The discovery of antibiotics and the introduction of novel materials in the last century breathed new life into the discipline. Since then, the usage of keratoprostheses for severe ocular surface disorders and corneal opacities has skyrocketed, to the point where it is now considered a common operation by corneal experts all over the world. The basic principle of replacing a damaged and opaque cornea with an artificial cornea, or keratoprosthetics, is as simple as putting a window in a house to be able to see out.
