Osteo-odonto-keratoprosthesis

Osteo-odonto-keratoprosthesis (OOKP) is a type of keratoprosthesis (artificial cornea) that uses a patient's own tooth and surrounding bone to support an optical cylinder. This procedure is typically used for patients with severe corneal and ocular surface disease who are not suitable candidates for a traditional corneal transplant.

History

The OOKP procedure was first described by Italian ophthalmologist Strampelli in 1963. It has since been refined and popularized by Professor Falcinelli, who performed over 600 OOKP surgeries during his career.

Procedure

The OOKP procedure is performed in two stages. In the first stage, a tooth and part of the surrounding bone are removed from the patient. The tooth and bone are then shaped into a support for the optical cylinder and implanted into the patient's cheek to allow for tissue growth. After a few months, the second stage of the procedure is performed. The tooth-bone-cylinder complex is removed from the cheek and implanted into the eye, replacing the damaged cornea.

Indications

OOKP is indicated for patients with severe corneal and ocular surface disease who are not suitable candidates for a traditional corneal transplant. This includes patients with Stevens-Johnson syndrome, ocular cicatricial pemphigoid, and severe chemical burns.

Complications

As with any surgical procedure, there are potential complications associated with OOKP. These can include infection, extrusion of the prosthesis, and retinal detachment.
