The Landers-Foulks temporary operating keratoprosthesis was used in the treatment of a severe double perforating injury involving both the cornea and retina in a 12-year-old boy. The use of the keratoprosthesis permitted surgical intervention at the optimal time for successful treatment of the retina and vitreous, providing the patient with useful visual acuity. The temporary keratoprosthesis is an excellent device for the subacute management of massive ocular trauma involving both anterior and posterior segments.
