Intraocular pressure (IOP) in the right eye of 113 patients was measured with one XPERT NCT air-puff non-contact tonometer (XPERT) and compared with IOP measured with one Goldmann applanation tonometer (GAT). Precision of the methods was judged by variance analysis, indicating that GAT was slightly more precise than XPERT. The slope of the linear relationship between the methods did not differ significantly from 1.0. Mean difference between the methods was 0.92 mmHg, XPERT measuring lower than GAT, p = 0.00017. The intra-individual difference between methods ranged from -8.00 to 8.67 mmHg, and standard deviation (SD) of differences was 2.52 mmHg. The 95% limits of agreement between the two methods were -5.85 to 4.01 mmHg. The SD of differences is of approximately the same size as previous XPERT vs GAT as well as previous GAT vs GAT studies.
使用一台XPERT NCT气吹式非接触眼压计（XPERT）测量了113例患者右眼的眼压，并与使用一台Goldmann压平眼压计（GAT）测量的眼压进行比较。通过方差分析判断方法的精密度，结果表明GAT比XPERT稍精确。两种方法之间线性关系的斜率与1.0无显著差异。两种方法的平均差异为0.92 mmHg，XPERT测量值低于GAT，p = 0.00017。两种方法之间的个体内差异范围为-8.00至8.67 mmHg，差异的标准差（SD）为2.52 mmHg。两种方法之间的95%一致性界限为-5.85至4.01 mmHg。差异的SD与之前XPERT与GAT以及之前GAT与GAT研究的大小大致相同。
