1. In our study, the Icare ic200 overestimated the IOP. The overestimation increased as the baseline IOP increased. The agreement between the IOP measurement by GAT and Icare ic200 was <2 mm Hg at all ranges of IOP. The narrow limits of agreement between the tonometers for an IOP <21 mm Hg makes it a useful alternative to GAT in this pressure range.
