To evaluate the intrasubject repeatability of the ocular aberrometry obtained with a new ocular pyramidal aberrometer technology in a sample of normal eyes.
A total of 53 healthy eyes of 53 subjects with ages ranging from 18 to 45 years were included in this study. In all cases, three consecutive acquisitions were obtained. Intrasubject repeatability of the measurements with a pyramidal aberrometer was calculated. Intrasubject repeatability for 4.0- and 6.0-mm pupils was evaluated within the subject standard deviation (S) and intraclass correlation coefficient.
Low values of the S and intraclass correlation coefficient outcomes close to 1 were observed for the sphere and cylinder at 3.0-mm pupil size. Most low S and intraclass correlation coefficient values close to 1 were observed for total, low-order aberrations and higher-order aberrations root mean square and for each Zernike coefficient analysis (intraclass correlation coefficient ⩾0.798) at 4.0-mm pupil size, with more limited outcomes for the aberrometric coefficient of Z(4, 4) with an intraclass correlation coefficient of 0.683. For a 6.0 mm pupil diameter, low S and intraclass correlation coefficient values close to 1 were observed for all aberrometric parameters or Zernike coefficients analyzed (intraclass correlation coefficient ⩾0.850).
The new pyramidal aberrometer Osiris provides repeatable and consistent measurements of ocular aberrometry measurements in normal eyes.
在正常眼样本中，评估采用新型眼锥面像差仪技术获得的眼像差测量结果的受试者内重复性。
本研究纳入了53名年龄在18至45岁之间受试者的53只健康眼睛。在所有情况下，均进行了连续三次采集。计算了锥面像差仪测量的受试者内重复性。在受试者标准差（S）和组内相关系数范围内，评估了4.0毫米和6.0毫米瞳孔的受试者内重复性。
在3.0毫米瞳孔大小时，球镜和柱镜的S值较低，组内相关系数结果接近1。在4.0毫米瞳孔大小时，对于总低阶像差、高阶像差均方根以及每个泽尼克系数分析（组内相关系数⩾0.798），观察到大多数较低的S值和接近1的组内相关系数值，而对于Z（4, 4）像差系数，组内相关系数为0.683，结果较为有限。对于6.0毫米瞳孔直径，在分析的所有像差参数或泽尼克系数中，观察到较低的S值和接近1的组内相关系数值（组内相关系数⩾0.850）。
新型锥面像差仪Osiris在正常眼中提供了可重复且一致的眼像差测量结果。
