• INTRODUCTION
• Galilei is a multifunctional system that
  integrates the two more valuable technologies
  presently
• available to study the cornea Placido
  reflection of rings and dual Scheimpflug imaging.
• Combined system displays maps with 14,400 point
  values of real topography, elevation and
  pachymetry calculated from 122,000 data points
  assessed from the cornea and the anterior segment
  of the eye

• Features
• Two Scheimpflug cameras
• Double Placido calculation
• Digital top view camera
• Iris recognition device
• Cyclotorsion correction
• Anterior surface topography
• Posterior surface topography
• Corneal Pachymetry
• Anterior chamber pachymetry
• Corneal 3-D densitometry
• Lens 3-D densitometry
• Biometry of anterior segment
• Zernike WF analysis of cornea
• Differential maps
• Zoom of all Scheimpflug images

• Applications
• Keratoconus diagnosis
• Preop/postoperative exams
• Follow up of corneal diseases
• Topographic biomechanical signs
• Cataract diagnosis
• Biometry of anterior segment
• Digital goniometry
• Eye photography
• Photographic records
• Corneal power for IOL calculation
• Postop of multi-focal toric IOLs
• WF study of the cornea
