title: Laser in situ keratomileusis for astigmatism greater than -3.50 D with the Nidek EC-5000 excimer laser.
abstract: OBJECTIVE
  LASIK with the Nidek EC-5000 excimer laser was used to treat high astigmatism.
  
  
  METHODS
  The Nidek EC-5000 excimer laser and ACS microkeratome were used in regular LASIK procedures. Results of 74 eyes with astigmatism of more than 3.50 D and up to 10.00 D were evaluated.
  
  
  RESULTS
  With Nidek algorithms, it was possible to eliminate refractive error completely or reduce it to a satisfactory amount, especially in difficult cases of mixed astigmatism with high astigmatic components.
  
  
  CONCLUSIONS
  The Nidek software for mixed and high astigmatism was efficient, predictable, and produced good results in difficult cases of high astigmatism.
