[Comparative characteristics of current tonometric methods].
Corneal thickness is known to have a considerable impact on the results of applanation tonometry. A Pascal dynamic contour tonomer (SMT Swiss Microtechnology AG) the readings of which are not affected by the properties of the cornea has recently come into the world market. The objective of the investigation was to comparatively evaluate Pascal, Goldmann, and Maklakov tonometers. The mean intraocular pressure measured by various procedures significantly differed. The greatest correlation was found between dynamic contour tonometry and Goldmann's tonometry. The Pascal and Goldmann tonometers underestimated data on remeasurements. The results of applanation procedures, unlike those of dynamic contour tonometry, depend on the data of keratopachymetry.
