title: Posterior-segment surgeries with a two-port modified multiport illumination system.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the safety and efficacy of a modified two-port multiport illumination system (MIS) in different vitreoretinal surgeries.
  
  
  METHODS
  Sixty-one patients had undergone pars plana vitrectomy for complications of retinal diseases with the modified MIS. Only two-port pars plana vitrectomy was performed with the MIS. Visual acuity, intraoperative and postoperative complications, intraocular pressure and the retinal reattachment rate were evaluated. The mean follow-up time was 3 months (range 1-6 months).
  
  
  RESULTS
  Visual acuity was stabilized in 40 (65.5%) of 61 eyes, improved in 15 eyes (24.5%) and deteriorated in 6 eyes (9.8%). No intraoperative complications occurred. Postoperative complications were hypotony in 12 eyes, rehemorrhage in 2 eyes and choroidal detachment in 1 eye. Five cases required conversion to standard three-port vitrectomy. Mean overall preoperative and postoperative intraocular pressures were 17.4 and 11.9 mm Hg, respectively.
  
  
  CONCLUSIONS
  Despite some limitations the modified MIS with two-port sclerotomy is a good, comfortable and safe option for posterior-segment surgeries.
