title: Pars plana vitrectomy for the management of retained lens material after cataract surgery.
abstract: OBJECTIVE
  To evaluate the management and outcomes of patients undergoing pars plana vitrectomy (PPV) for retained lens material after cataract surgery; and to evaluate risk factors for poor visual outcome, retinal detachment, raised intraocular pressure (IOP), and cystoid macular edema (CME).
  
  
  METHODS
  Retrospective interventional consecutive case series.
  
  
  METHODS
  setting: Institutional and Clinical practice. study population: Patients with retained lens material after cataract surgery who underwent vitrectomy at Sydney Eye Hospital between July 1, 1998 and October 31, 2003. intervention: Standard three-port PPV/lensectomy. main outcome measures: Final best-corrected visual acuity (BCVA), retinal detachment, raised IOP, and CME.
  
  
  RESULTS
  A total of 223 eyes of 223 patients were included, with a mean follow-up of 20.5 months after vitrectomy. Final BCVA was 6/12 or better in 159 patients (71.3%). Retinal detachment occurred in 20 patients (9%), with 11 diagnosed before or during vitrectomy, and nine occurring after vitrectomy. Ten patients (5.0%) developed raised IOP and 42 (23.2%) developed CME. Poor final visual acuity was associated with retinal detachment (P = .0026), and with poor visual acuity at presentation (P = .030). There was a significant association between retinal detachment and a long interval (>30 days) between cataract surgery and vitrectomy (P = .00047) and between retinal detachment and younger age (P = .0070).
  
  
  CONCLUSIONS
  Visual acuity results in this study compared favorably with previously published reports. Although the overall rate of retinal detachment was low, it was significantly higher in those with a delayed interval between cataract surgery and vitrectomy, and was significantly associated with a poorer visual outcome.
