title: Risk factors of acute endophthalmitis after cataract extraction: a case-control study in Asian eyes.
abstract: OBJECTIVE
  To describe risk factors of acute endophthalmitis after cataract extraction in an Asian population.
  
  
  METHODS
  A retrospective, case-control study. Cases (n = 34) were patients with acute endophthalmitis presenting within 6 weeks after cataract surgery. Three controls per case (n = 102) were randomly selected from the cataract surgery list matched on the date of operation of cases.
  
  
  RESULTS
  Few risk factors were identified. In multivariable analysis, endophthalmitis was associated with silicone intraocular lens (odds ratio 5.1, 95% confidence intervals, 1.2 to 21.6, compared to poly(methylmethacrylate) lens) and posterior capsular rupture during surgery (odds ratio 20.9, 95% confidence intervals 2.3 to 187.9).
  
  
  CONCLUSIONS
  Silicone intraocular lens and rupture of the posterior capsule are risk factors of acute endophthalmitis after cataract surgery.
