Anaesthetic implications of osteo-odonto-keratoprosthesis surgery.
Patients with bilateral corneal blindness in whom corneal transplantation has either been unsuccessful or inappropriate may be considered for osteo-odonto-keratoprosthesis surgery. During a two-stage procedure the surface of the cornea is removed and covered with a graft of buccal mucosa. An optical cylinder, supported by an osteo-odonto lamina planed from a tooth is then inserted into the mucosa to act as a lens. The anaesthetic implications of this operation include care of patients from a wide age range, often with underlying medical problems undergoing two operations of prolonged duration. The eye can be 'open' during both stages of the operation and anaesthetic techniques directed towards prevention of rises in vitreal pressure are essential. This article outlines the surgical process of osteo-odonto-keratoprosthesis surgery with reference to our anaesthetic experiences from nine cases.
