The new measuring technique uses an ultra-high-speed Scheimpflug camera in combination with an air pulse to determine IOP values with great precision. Initial studies have confirmed the high degree of reproducibility in comparison to that obtained by Goldmann applanation tonometry and non-contact tonometry1).
The measurement principle employed here ensures results uninfluenced by such factors as insufficient tear film or patient positioning. Automatic release and specified measurement quality guarantee user-independent data. Up to 6 measurements can be taken, and the average IOP is printed out or displayed. IOP measurements can be corrected with the aid of pachymetry-based correction tables including the Dresden correction table and the new Spoerl correction table, which takes patient age into account.
