The Schwind Workstation is the ideal formation with which you can do all refractive surgeries. A accurate wavefront abberation analysis can be made with the Schwind Wavefront Analyzer high resolution Hartmann-Shack sensor. These data are exportable to the Schwind Amaris excimer laser. The Schwind Siris combines a 3D rotating Scheimplug camera with a Placido disc topographer. Both devices can be controlled with the Schwind Workstation with one single computer and the excentive analysis can be exported as a result to the Schwind Amaris in combination with other patient data.
