abstract: OBJECTIVE
  Evaluation of the usefulness of corneal scanning topography performed with Orbscan for the localization of corneal graft due to keratoconus.
  
  
  METHODS
  We examined 33 eyes in 33 individuals (23 men 10 women) during one year 2000/2001. Corneal topography was performed with Orbscan apparatus before the transplantation of the cornea due to the keratoconus. Trepanning depended of the thickness of peripheral cornea. Visual acuity without correction was compared with the control group of 33 eyes, after corneal transplantation done due to the corneal cone between 1998-1999, without consideration of scanning topography.
  
  
  RESULTS
  Significant differences in the post-surgical visual acuity in favor of the examined group in the range from 5/5 to 5/7 and from 5/25 to 5/50 were observed.
  
  
  CONCLUSIONS
  Scanning corneal topography will probably facilitate proper qualification for the transplantation and better postoperative visual acuity.
