To compare Plusoptix (Gmbh, Nuremberg, Germany), 2WIN (Adaptica, Padua, Italy), the benchtop refractometer (Auto-Kerato-Refractometer KR-8900; Topcon Co, Tokyo, Japan), and retinoscopy with regard to the consistencies.
In our prospective study, 200 eyes of 100 patients were included. We analyzed the demographics and characteristics of the patients, the percentage of patients from whom measurements could not be obtained, the measurements from both patients' eyes of pupil diameter, spherical, cylindrical, axis, and spherical equivalence.
The mean age ± SD was 7.8±4.5 years (range, 1-18 years). Pupil diameter measurements were found to be consistent (Cronbach's alpha value >0.8). The sphere and spherical equivalence measurements for both eyes were found to be consistent with each other in all apparatus (Cronbach's alpha value >0.8). However, consistency was found to be lower in cylindrical values and the Jackson cross-cylinder measurements at 0° and 45° axis were found to be inconsistent with each other (Cronbach's alpha value <0.8).
While consistency was observed in all methods in terms of sphere and spherical equivalence, consistency dropped in cylindrical values and no consistency was observed in axis values. It is important to take this point into consideration, especially in axis measurements.
比较Plusoptix（德国纽伦堡Gmbh公司）、2WIN（意大利帕多瓦Adaptica公司）、台式验光仪（自动角膜验光仪KR - 8900；日本东京拓普康公司）以及检影法在一致性方面的表现。
在我们的前瞻性研究中，纳入了100例患者的200只眼睛。我们分析了患者的人口统计学特征和特点、无法获得测量值的患者百分比、患者双眼的瞳孔直径、球镜、柱镜、轴位以及等效球镜的测量值。
平均年龄±标准差为7.8±4.5岁（范围为1 - 18岁）。发现瞳孔直径测量值具有一致性（克朗巴哈系数值>0.8）。在所有仪器中，双眼的球镜和等效球镜测量值彼此一致（克朗巴哈系数值>0.8）。然而，发现柱镜值的一致性较低，并且在0°和45°轴位的交叉柱镜测量值彼此不一致（克朗巴哈系数值<0.8）。
虽然在球镜和等效球镜方面所有方法都观察到了一致性，但柱镜值的一致性下降，轴位值未观察到一致性。尤其在轴位测量中考虑到这一点很重要。
