Example of 40x probe exam Confoscan 4 probes - 20x, 40x, 40x with Z-Ring exam images of different layer and pathologies

The World Standard in Corneal Diagnostic

Precise display of corneal layers

  • Endothelium
  • Descemet's membrane
  • Stroma
  • Bowman's membrane
  • Epithelial layers

Accurate analysis of corneal components

  • Endothelial cells
  • Stromal Keratocytes
  • Nerve Fibres
  • Basal & Superficial Cells



  Main Features      
  • Confoscan 4 is a unique and state-of-the-art diagnostic instrument that combines a Confocal Microscope, a non-contact Endothelial Microscope and a precision Pachymeter – all technologies in one innovative and compact unit.

  • The Confoscan 4 is the first Confocal Microscopy Based Pachymeter able to do full thickness cornea measurements and to localize any intra-corneal structure, including haze.

  • The Confoscan 4 is the first Fully Automated Non-Contact Confocal Endothelial Microscope that is not affected by corneal hazes. The unit provides for a fast and fully automatic endothelial analysis in any condition. Confocality is at its highest performance with a fourth generational NIDEK Confocal Microscope.
  exam images of different layer and pathologies  


  • Automated functionalities like automatic alignment and scanning make testing, registration and evaluation of the data easier and faster than with other confocal instrumentation.

  • The new Z-Ring and high precision optics increase the stability and accuracy of the exam.

  • The new internal fixation targets lead to highly reproducible and accurate exams, a single button push allows automatic retesting of a patient in 9 different corneal locations.

  • A quick exam time and NO-Contact characteristics and floating probe system, make the exam process comfortable and safe even for light sensitive patients or for those that have undergone ophthalmic surgery.

  Example of 40x probe exam  
  • Automatic cell analysis software detects overall density, number of sides and area of each cell as well as overall pleomorphism and polimegathism indices.

  • Fully Automatic, Semi-Automatic, Manual Mode and Customisable exam parameters are available with the unit. This allows you to choose the corneal layers to be scanned - Endothelium, Epithelium or Full cornea scan in one unique patient exam.
