目的.评估Galilei Dual Scheimpflug分析仪（GDSA）、生物计IOL Master和自动角膜/屈光计WAM 5500在眼前节检查中的正常值和可重复性。方法.前瞻性连续招募88例健康志愿者的88只眼。评估重复性，计算组内相关系数（ICC）。结果重复测量之间的相关性显示，除了角膜散光Galilei（0.79）和WAM（0.68）外，所有参数的可靠性均接近完美（ICC > 0.81）。通过GDSA和其他方法测量的平坦模拟角膜曲率（SimK）和陡峭SimK值之间存在统计学显著差异（P < 0.001）;但是，使用IOL Master和WAM 5500获得的值之间没有统计学显著差异（分别为P = 0.302和P = 0.172）。或在IOL Master和GDSA测量的ACD（P < 0.001）和WTW（P = 0.007）之间。结论. IOL Master和WAM 5500的眼前节测量结果具有高度可重复性、可比性和良好相关性。在健康的年轻人中，评价的参数具有很好的重复性，尽管GDSA和IOL Master之间以及GDSA和WAM 5500之间存在显著差异。
Purpose. To assess the normal values and the repeatability of the Galilei Dual Scheimpflug Analyzer (GDSA), the biometer IOL Master, and the autokerato/refractometer WAM 5500 in anterior segment examinations. Methods. Eighty-eight eyes from 88 healthy volunteers were prospectively and consecutively recruited. The repeatability was assessed, calculating the intraclass correlation coefficient (ICC). Results. The correlations among the repeated measurements showed nearly perfect reliability (ICC > 0.81) for all of the parameters, except corneal astigmatism Galilei (0.79) and WAM (0.68). There were statistically significant differences (P < 0.001) between the values of the flat simulated keratometry (SimK) and the steep SimK measured by GDSA and the other methods; however, there were no statistically significant differences for the values obtained with the IOL Master and WAM 5500 (P = 0.302 and P = 0.172, resp.) or between the values of the ACD (P < 0.001) and WTW (P = 0.007) measured by the IOL Master and GDSA. Conclusions. The anterior segment measurements from the IOL Master and WAM 5500 were highly repeatable, comparable, and well correlated. In healthy young persons, the evaluated parameters had very good repeatability, although significant differences were found between the GDSA and IOL Master and between the GDSA and WAM 5500.
