title: Boston keratoprosthesis for keratopathy in eyes with retained silicone oil: a new indication.
abstract: OBJECTIVE
  To analyze the visual outcome of Boston keratoprosthesis for keratopathy in silicone oil-filled eyes.
  
  
  METHODS
  Retrospective chart review of patients with silicone oil-induced keratopathy undergoing Boston keratoprosthesis between January 2008 and June 2010 was performed. Patients received Boston keratoprosthesis as the primary procedure or after a failed penetrating keratoplasty because of silicone oil-induced keratopathy after assessing possible visual potential. Silicone oil had to be retained in all eyes because of persistent ocular hypotony.
  
  
  RESULTS
  Of the 8 eyes that underwent surgery, anatomic retention and visual improvement were noted in 7 eyes (87.5%). The visual acuity improved to 20/200 or better in 6 eyes (66.67%). Repeated corneal melt necessitated the removal of the prosthesis with corneal transplant in 1 eye. Membranectomy was performed twice for retroprosthetic membrane in 1 eye.
  
  
  CONCLUSIONS
  Boston keratoprosthesis seems to be a viable option for visual rehabilitation in postvitrectomized eyes with a decrease in vision due to retained silicone oil-induced keratopathy.
