Eyes are the “Windows to the soul;” the cornea is the “Front Window of the eye.” The most grievous yet, unfortunately, the most commonly occurring loss out of all sensory organs is that of an eye.
The importance of corneal disease as a major cause of blindness in the world today remains second only to cataract; however, its epidemiology is complicated and encompasses a wide variety of infectious and inflammatory eye diseases. The general treatment for serious corneal disease is corneal graft by penetrating keratoplasty. However, penetrating keratoplasty failure is virtually certain when the ocular surface is severely compromised. Keratoprosthesis represents the only viable option for restoring sight in these patients.
A unique approach to the artificial corneal problem, the OOKP, was developed in Italy by Strampelli in 1963. it will seem probable that if a plastic acrylic implant could be held in a piece of the patient’s tooth and bone, and the whole placed in a corneal envelope, the tooth, and the bone will form an autograft picture frame for the acrylic and so prevent its extrusion.Strampelli’s device used a lamina prepared from a single root tooth with surrounding bone sawn from the patient jaw bone, into which the poly (methyl methacrylate) optic was cemented. Following pioneering work of Strampelli, Falcinelli made stepwise improvements to the original technique, ensuring good long‑term visual and retention. Over the past few years, the procedure has undergone further refinements, which are referred to as the Rome–Vienna protocol.
