title: MANAGEMENT OF VITREAL LOSS FROM POSTERIOR CAPSULAR RUPTURE DURING CATARACT OPERATION: Posterior Versus Anterior Vitrectomy.
abstract: OBJECTIVE
  To compare the efficacy between 23-gauge sutureless pars planar vitrectomy (PPV) and anterior vitrectomy in the management of vitreous loss associated with posterior capsular rupture during cataract surgery.
  
  
  METHODS
  Medical records of 139 eyes which sustained posterior capsular rupture and vitreal prolapse to anterior chamber during cataract surgery were retrospectively reviewed. Thirty-two eyes which underwent 23-gauge sutureless PPV (group PPV) and 107 eyes which underwent anterior vitrectomy (group AntV) were compared in postoperative visual and anatomical outcomes, operation time, and complications.
  
  
  RESULTS
  No significant differences were found between the groups in final best-corrected visual acuity of 20/40 or better (AntV vs. PPV = 80.4 vs. 90.6%, P = 0.139). However, the visual recovery rates (20/40 or better) 1 day, 1 week, 1 month postoperatively were significantly higher in group PPV (AntV vs PPV = 22.4 vs. 44%, 32.2 vs 58.6, 51.9 vs. 78.1%). Postoperative intraocular pressure-related complications requiring medication were less evident in group PPV (AntV vs. PPV = 52.3 vs. 6.3%, P < 0.001). Twelve cases (11.2%) of group AntV and 0 cases of group PPV underwent secondary operation during follow-up. Although no postoperative complications occurred in group PPV, complications such as endophthalmitis, retinal detachment, cystoid macular edema, intraocular lens instability were observed in the AntV group (none vs. 14%, P = 0.022).
  
  
  CONCLUSIONS
  Twenty-three-gauge sutureless PPV is a safe and reliable solution for managing vitreous loss during cataract surgery. Therefore, it is expected to be considered primarily in institutes with vitreoretinal surgeons.
