title: Postoperative complications following vitrectomy for proliferative diabetic retinopathy with sew-on and noncontact wide-angle viewing lenses.
abstract: OBJECTIVE
  To compare the occurrence of vitreous hemorrhages and retinal detachments following vitrectomy surgery with sew-on lenses to a noncontact wide-angle lens system.
  
  
  METHODS
  Retrospective review of 180 patients who underwent primary vitrectomy for proliferative diabetic retinopathy. The occurrence of persistent and recurrent vitreous hemorrhages as well as postoperative retinal detachments in the two groups was determined.
  
  
  RESULTS
  There was no statistically significant difference in the occurrence of persistent vitreous hemorrhages between the sew-on (55%) and the wide-angle (42%) lens systems (P = 0.099). Likewise, recurrent vitreous hemorrhages were similar in both the sew-on (15%) and the wide-angle (17%) lens systems (P = 0.838). However, postoperative detachments were more frequent in the sew-on group (9%) than in the wide-angle (1%) group (P = 0.046).
  
  
  CONCLUSIONS
  In patients with proliferative diabetic retinopathy, using a wide-angle noncontact lens system significantly reduced the incidence of postoperative retinal detachments, but not persistent or recurrent vitreous hemorrhages.
