title: Deviated hydroxyapatite orbital implant syndrome.
abstract: OBJECTIVE
  To describe a patient with a deviated orbital implant after enucleation.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  We examined a postenucleation patient with a medially deviated ("esotropic") implant after peg drilling. Modification of the posterior surface of the prosthesis improved cosmesis in the primary position.
  
  
  CONCLUSIONS
  During enucleation surgery, surgeons may use a spherical implant rather than modify the anterior face in patients with preexisting strabismus, with severe trauma to the extraocular muscles, or with risk of implant deviation. Additionally, secondary procedures may alter implant position. Occasionally, patients without obvious preoperative risk factors may have deviation of the modified face of the implant. Flattening the implant creates an asymmetric surface that may lead to a deviated orbital implant.
