Purpose:
To describe and further analyze the long-term results in visual acuity (VA), anatomical retention, and rate of complications from patients who underwent Boston keratoprosthesis (B-Kpro) type 1 after ocular chemical burns in the Dominican Republic.
Methods:
A retrospective review of 42 eyes (22 OD:20 OS) of 36 patients who underwent B-Kpro type 1 implantation after severe ocular burn at Hospital Elías Santana in Santo Domingo, Dominican Republic, between April 2006 and October 2014, were included.
Results:
Demographics, VA, anatomical retention, and the rates of postoperative complications and concurrent surgeries were evaluated.
Conclusions:
The excellent anatomical retention rates and visual outcomes presented in this study support the remarkable capability of B-Kpro type 1 to restore functional VA in eyes with severe chemical injuries. However, strict control of the postoperative complications is necessary for long-term success. In conclusion, the use of a B-Kpro type 1 after severe chemical burn is a viable option in patients otherwise condemned to the high risk of failure associated with conventional corneal grafts.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
