How to measure

The measurement technique with the slit lamp is similar to a Goldmann measurement.

There are five main differences

  • no fluorescein - just a drop of anesthetic
  • switch PASCAL on and center nicely on the middle of the cornea
  • advance the PASCAL until the leverarm is upright
  • fineadjust looking through the slitlamp
    center the contact area (black rim) to the middle of the cornea
  • measure listening to the melody of IOP untill you hear the Q-indicator-tone
