title: Automated visual axis alignment for refractive excimer laser ablation.
abstract: OBJECTIVE
  To describe the use of new laser alignment and delivery software in the NIDEK Advanced Vision Excimer laser platform (NAVEX) that allows centration based on surgeon specification.
  
  
  METHODS
  Descriptive article with a case report.
  
  
  RESULTS
  The software allows specification via numeric entry of the exact placement of the laser tapered to the position of the visual axis or the line of sight.
  
  
  CONCLUSIONS
  The ability to specify the exact location of the laser ablation based on pupil position is fundamental in patients undergoing custom ablation and those with eccentric fixation. A conservative treatment strategy is recommended for initial experience with this alignment software.
