title: Vitreoretinal surgery in eyes with Pintucci biointegrable keratoprosthesis.
abstract: OBJECTIVE
  The purpose of this study was to describe the challenges in preoperative evaluation, complexity of surgical maneuvers, and intricacies of postoperative management in eyes with Pintucci biointegrable keratoprosthesis requiring vitreoretinal intervention. Ocular surface disorders like Stevens-Johnson syndrome, chemical burns, and ocular cicatrical pemphigoid render the eye inamenable to penetrating keratoplasty. Hence, permanent keratoprosthesis is used for visual rehabilitation in such eyes. Management of vitreoretinal complications in such eyes is a challenging situation because of the difficult approach, limited visibility and maneuverability, and meticulous postoperative care.
  
  
  METHODS
  Five patients (mean age: 18 years) with Pintucci biointegrable keratoprosthesis who underwent surgical intervention for vitreoretinal disorders between 2003 and 2008 were evaluated. All patients underwent pars plana vitrectomy with adjunct procedures and intraocular tamponade.
  
  
  RESULTS
  Retinal reattachment was achieved in all cases. Mean best corrected visual acuity improved from 20/10,000 to 20/1,200. Mean duration of follow-up was 108 days.
  
  
  CONCLUSIONS
  Vitreoretinal surgery in eyes with Pintucci biointegrable keratoprosthesis is a highly challenging situation that requires intricate planning and an integrated approach. However, it can result in good anatomical and functional outcomes.
