title: Clinical evaluation of the Dicon CAT 100 applanation tonometer.
abstract: A comparison of the Dicon CAT 100 applanation tonometer with the Goldmann tonometer in anesthetized human eyes with normal corneas disclosed high correlations for low, intermediate, high, and mean readings, but regression analysis showed that the y intercept was significantly different from 0 and that the slope was different from 1. The CAT 100 systematically overestimated low intraocular pressure levels and underestimated high intraocular pressure levels and thus is not accurate enough for clinical use.
