• Contact and immersion methods
• Automatic control of measurement scatters (with manual correction)
• Calculations of means and standard deviations
• Automatic TGC adjustment;GAIN adjustment up to 110dB
• Memory of 20 scans with measurements for further analysis
• Probe with central light beam for correct eye positioning
• Customizable for 10 users,  10 profiles for each.
• Adjusting  and test via attached calibrator.

SPECIFICATIONS:

 -  probe frequency - 12 MHz

 -  range of scan 40 mm 

 -  clinical resolution   0.1 mm 

 -  electronic resolution  –/+ 0.01 mm

• Quick measurements of thickness for all corneal  types

  - automatic and manual measurements

  - measurement of thickness at arbitrarily selected points

  - calculation of mean from measurements

  - standard deviation of the measured thickness

  - ability for rejecting uncorrected  measurements

• Very high level of accuracy and repeatability of all measurements:

  - sophisticated algorithms  for the accuracy improvement 
  - very high frequency for measuring purpose- 400 MHz

  - high averaging ratio - 512 automatic measurements cycles.  

• Intra-ocular pressure (IOP) calculations with  measuring  and/or manual correction
• Five IOP correction formulas : (Kohlhas/Shah, Herndon/ Doughty, Whitacre et al., Ehlers et al., custom - own)
• BIAS percentage deviation of the measured thickness from 60% to 130%
• TEST function for automatic checking the correctness of operation (without using external phantoms or patterns)
