title: Tilt and decentration of the intraocular lens following combined vitrectomy and pars plana lensectomy.
abstract: OBJECTIVE
  To investigate intraocular lens (IOL) tilt and decentration following combined vitrectomy and pars plana lensectomy (PPL) with IOL implantation in patients with proliferative diabetic retinopathy.
  
  
  METHODS
  We followed 25 patients with proliferative diabetic retinopathy who underwent PPL and IOL (MA60BM) implantation at the time of pars plana vitrectomy (PPL group), and 25 patients who underwent phacoemulsification and IOL (MA60BM) implantation without vitrectomy (PE group). Intraocular lens tilt and decentration were evaluated quantitatively, using the anterior eye segment analysis system, approximately 12 months after surgery.
  
  
  RESULTS
  There was no significant difference in IOL tilt (p = 0.47) or decentration (p = 0.26) between the PPL and PE groups.
  
  
  CONCLUSIONS
  The present study suggests that tilt and decentration of the IOL are acceptable in combined vitrectomy and pars plana lensectomy.
