PACHYMETER

  • 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)
