title: Boston type 1 keratoprosthesis for severe blinding vernal keratoconjunctivitis and Mooren's ulcer.
abstract: Indications for the Boston keratoprosthesis differ throughout the world depending on the prevailing regional causes of end-stage corneal disease. We report the short term anatomical and functional outcomes of the Boston type 1 keratoprosthesis for severe bilaterally blinding vernal keratoconjunctivitis and Mooren's ulcer. A retrospective chart review was conducted of 2 patients who underwent several unsuccessful ocular surface reconstruction procedures before Boston type 1 keratoprosthesis implantation. The anatomical and visual outcomes of the Boston type 1 keratoprosthesis at 1 year of follow-up were assessed clinically and by anterior segment optical coherence tomography imaging. The keratoprosthesis was retained in both the eyes at 1 year postoperatively with a best-corrected visual acuity of 20/30 in both patients. To our knowledge this is the first report of successful Boston keratoprosthesis implantation for these two unusual indications.
