title: [Corneal astigmatism after trabeculectomy].
abstract: OBJECTIVE
  The aim of the present study was to investigate the effect of conventional and mitomycin trabeculectomy on the corneal astigmatism.
  
  
  METHODS
  Measurements with the use of computer-assisted videokeratography (Eye-Sys) were performed in 34 glaucoma patients who underwent trabeculectomy. Color-coded topography maps were analyzed to obtain astigmatic data.
  
  
  RESULTS
  The mean surgically-induced astigmatism in conventional trabeculectomy group was 2.2 D and in the mitomycin group 4.0 D, 1 day post-op, 1.3 D and 3.0 D after 10 days and 0.4 D and 1.1 D after 3 months, respectively.
  
  
  CONCLUSIONS
  There was an apparent correlation between the amount of induced astigmatism and the use of mitomycin. This may be related to the impaired healing process of trabeculectomy wound and lower intraocular pressure in the mitomycin group.
