title: The development of cataract following trabeculectomy.
abstract: OBJECTIVE
  To determine the risk of cataract development following trabeculectomy.
  
  
  METHODS
  A prospective follow-up study of patients seen pre-operatively and at one, three, six and 12 months following surgery and subsequently at yearly intervals.
  
  
  METHODS
  Ophthalmology Department of Nottingham University Hospital.
  
  
  METHODS
  Fifty-seven patients with primary open angle glaucoma, including pseudoexfoliation, undergoing trabeculectomy.
  
  
  METHODS
  Increases in lens opacity measured by the Lens Opacity Meter 701, the Keeler Projectoscopy and clinical grading.
  
  
  RESULTS
  Of 35 patients seen at six months post-operatively, none had lost two Snellen lines of visual acuity due to lens opacity, although three patients showed evidence of increasing lens opacity on all three parameters.
  
  
  CONCLUSIONS
  There is no evidence of visually significant lens opacity occurring at six months post-operative follow-up.
