title: Delayed visual loss after pars plana vitrectomy for retained lens fragments.
abstract: OBJECTIVE
  To report visual results and postoperative complications in patients undergoing vitrectomy for retained lens fragments.
  
  
  METHODS
  Retrospective, noncomparative, interventional case series of 42 consecutive patients undergoing vitrectomy for retained lens fragments by a single surgeon, all with a minimum of 6 months' follow-up. The main outcome measurement was best corrected visual acuity at 3 months and at final follow-up visit.
  
  
  RESULTS
  Although 67% of eyes achieved a postoperative visual acuity of 20/40 or better at 3 months, 17% had events during follow-up that resulted in loss of vision to less than 20/40. Final best corrected visual acuity 20/40 or better was achieved in 50% of eyes. Retinal detachment occurred in 17%, and 21% of eyes required long-term therapy for glaucoma.
  
  
  CONCLUSIONS
  Patients undergoing vitrectomy for retained lens fragments often develop delayed visual loss. Long-term surveillance is necessary in these patients.
