title: Influence of postoperative lens status on intraocular pressure in proliferative vitreoretinopathy.
abstract: OBJECTIVE
  To determine the influence of lens status on postoperative intraocular pressure (IOP) in eyes undergoing vitrectomy for repair of recurrent retinal detachment (RD) resulting from proliferative vitreoretinopathy (PVR).
  
  
  METHODS
  Retrospective, consecutive, nonrandomized, single-center series.
  
  
  METHODS
  One hundred and forty-five eyes with recurrent RD resulting from PVR were reviewed retrospectively. In all, 99 eyes underwent relaxing retinotomy at the time of surgery (68.4%). Perfluorocarbon gas (n = 60) or silicone oil (n = 85) were used as postoperative tamponades. For analysis, eyes were subdivided first based on tamponade and retinotomy status. The resultant groups then were divided further by lens status into 2 groups: aphakic eyes (aphakic group) and phakic and pseudophakic eyes (nonaphakic group).
  
  
  RESULTS
  Surgical reattachment was achieved in all eyes except one. Eyes receiving both silicone oil and relaxing retinotomy had the worst baseline characteristics compared with those receiving other interventions. In this subset of eyes, a significantly lower proportion of hypotony was found in those eyes that were aphakic after surgery when compared with those eyes that were nonaphakic (P = .037).
  
  
  CONCLUSIONS
  Surgical management of PVR often results in ultimate retinal reattachment. In eyes receiving both relaxing retinotomy and silicone oil, higher IOPs and a lower proportion of hypotony are found where a native lens or intraocular implant is absent. Removal of the lens or intraocular implant may be considered for those eyes at greatest risk of hypotony.
