Background: Osteo-odonto-keratoprosthesis (OOKP) is a radical procedure that was developed 50 years ago by Strampelli, working uniquely for a hostile dry keratinised ocular surface. It is currently the keratoprosthesis of choice for patients with inflammatory corneal blindness, using the patient's own tooth root and alveolar bone to support a central optical cylinder. The cylinder replaces the optical elements of the eye, providing significantly improved image resolution and quality.
Case description: A 54-year-old Caucasian female presented with Stevens-Johnson syndrome secondary to a prolonged course of diclofenac. Initially the patient had symptoms of dryness, however this developed into left corneal perforation and required tectonic lamellar grafts. The grafts however failed, and the disease further progressed causing bilateral keratinisation, vascularised, scarred and thinning of her peripheral cornea. Her visual acuity was perception of light in her right eye and hand movements in her left. Due to the extent of her disease, she was suitable for OOKP in the left eye. After the procedure performed over 2 years, her final corrected visual acuity was 6/4 in her left eye.
Conclusions: This case report demonstrates the primary indication for OOKP and aims to increase awareness of the treatment option. It has the potential to dramatically improve the visual acuity in patients resulting in a better quality of life.
