WebFor every 100-microm increase in CCT, the difference (Icare-GAT) increased by 1 mm Hg. Of the 38 consecutive patients surveyed, 28 (73.7%) rated the Icare more comfortable than GAT, with only 2 (5.3%) rating it less comfortable (P<0.001). Conclusions: There is good correlation between the 2 methods of IOP measurement, even at extremes of IOP ... WebHowever, IOP measurements by GAT have been shown to be affected by the central corneal thickness (CCT), irrespective of the tonometer used. 3,4 Although it is considered necessary to adjust IOP by CCT for proper evaluation of IOP, Herndon 5 has suggested that the results vary, even when using various algorisms.
