Osteo-Odonto-Keratoprosthesis Service

Osteo-odonto-keratoprosthesis (OOKP) surgery is a specialist surgical intervention that can restore meaningful vision to patients suffering from end stage corneal blindness, and for whom conventional corneal surgery is not possible for reasons such as severe ‘dry eyes’ causing heavy scarring of the cornea. OOKP is only contemplated in patients where no other treatments would restore sight.

Treatment Procedure for Corneal Blindness

During Osteo Odonto Keratoprosthesis Services patients are initially assessed by ophthalmic and maxillofacial consultants, involving examination of the eyes, teeth and mouth. OOKP is then a two-stage procedure that firstly involves the extraction of the patient’s own tooth and bone, which are then fashioned into a ‘bolt’ and placed within the eye for supporting a synthetic optical cylinder.

The second stage of the procedure for Corneal Blindness Treatment is performed around four months after the first stage. Each surgical procedure lasts around six hours and patient required life-long follow-up.
