title: Pars Plana Vitrectomy Combined With Either Secondary Scleral-Fixated or Anterior Chamber Intraocular Lens Implantation.
abstract: OBJECTIVE
  To compare visual outcomes among eyes that underwent pars plana vitrectomy (PPV) in combination with either anterior chamber intraocular lens implantation (ACIOL) or scleral suturing of posterior chamber lens (PCIOL).
  
  
  METHODS
  Retrospective comparative case series.
  
  
  METHODS
  All eyes presented with aphakia or luxated or subluxated posterior chamber intraocular lens (IOL) following complicated cataract surgery, trauma, or spontaneous dislocation. Eyes involving visually significant macular pathology, past retinal detachment, follow-up of less than 6 months, and surgeries requiring the removal of an ACIOL were excluded. The main outcomes measured were final best-corrected visual acuity (BCVA) and surgical complication rates.
  
  
  RESULTS
  Fifty-seven eyes met inclusion criteria; median follow-up was 13.2 months. Initial median BCVA for ACIOL patients was logMAR 1.301 (Snellen equivalent 20/400, range 20/20 to light perception); final median BCVA was logMAR 0.477 (Snellen equivalent 20/60, range 20/20 to light perception, P < .001). Initial median BCVA for PCIOL patients was logMAR 1.239 (Snellen equivalent 20/347, range 20/60 to light perception); final median BCVA was logMAR 0.301 (Snellen equivalent 20/40, range 20/20 to hand motions, P < .001). The change in BCVA between the 2 groups over the course of the study was similar (P > .05). More epiretinal membrane (ERM) formations occurred postoperatively in the ACIOL group (P = .011). Other complication rates were similar between both groups.
  
  
  CONCLUSIONS
  PPV with secondary IOL placement is safe and effective, resulting in improved visual outcomes regardless of the technique used. Patients undergoing ACIOL placement have a higher incidence of ERM formation.
