Purpose
The purpose of this report was to describe a new alternative surgical technique combining oral mucosa and the Boston Keratoprosthesis type II (BKPro II) in a patient with severe chemical burn.
Setting
Cruces University Hospital, Spanish Tertiary Eye Care Hospital, a reference center.
Methods
We present a case of a 37-year-old man who suffered a severe bilateral chemical burn. Visual acuity was light perception and projection in both eyes. After many surgeries, he presented a corneal thinning in his right eye that was managed with an autologous oral mucosa graft. Considering the limited function of the eyelids, mild symblepharon, and dry ocular surface, we proposed the implantation of a BKPro II. Osteo-odonto-keratoprosthesis or tibial bone keratoprothesis was discarded at the patient’s express wish. A year and a half later, the oral mucosa was transplanted, and once the ocular surface was stabilized, we performed the transmucosal implantation of the BKPro II modifying the standard procedure.
Results
After 65 months of follow-up, the patient did not develop any complications, his visual acuity is stable (0.3 decimal), and funduscopic examination showed a pale optic disk, vascular tortuosity, and an epiretinal membrane that remains stable up to this period.
Conclusions
Transmucosal BKPro II may be considered as an alternative surgical technique for implant support in BKPro II carriers who want to improve their cosmesis avoiding, avoid complete tarsorrhaphy, and do not want to be exposed to dental or bone surgeries.
