title: Surgical outcomes for primary rhegmatogenous retinal detachments in phakic and pseudophakic patients: the Retina 1 Project--report 2.
abstract: OBJECTIVE
  To compare anatomical and functional outcomes for 546 phakic and pseudophakic primary rhegmatogenous retinal detachments (RDs) treated by pars plana vitrectomy or scleral buckling.
  
  
  METHODS
  Prospective, non-randomised, interventional study in 15 centres in Spain and Portugal, with data from RDs consecutively treated from January 2005 to May 2007. Cases with preoperative proliferative vitreoretinopathy grade C-1 or higher and perforating trauma were excluded. Minimum follow-up was 3 months. Twenty-seven pre-, intra- and post-surgical variables for each patient were analysed. Multivariate analysis was carried out by logistic regression analysis with stepwise selection of variables.
  
  
  RESULTS
  Data from 546 patients were analysed. Global anatomical success was 94.7%. Logistic regression analysis showed that only the development of postoperative proliferative vitreoretinopathy was associated with a poor anatomical outcome. The poorest functional results were associated with macular involvement, extension of RD, previous RD surgery, time of evolution of RD, and age of patient. Hierarchical log-linear analysis showed no effect of the lens status (phakic versus pseudophakic) on the functional results. However, pars plana vitrectomy was most often performed in pseudophakic eyes and resulted in a worse final visual acuity (p<0.001).
  
  
  CONCLUSIONS
  No differences in anatomical success between phakic and pseudophakic eyes were found in this series. Pars plana vitrectomy was most often performed in pseudophakic eyes and had a greater probability of a worse final visual acuity than scleral buckling.
