To evaluate the repeatability of a pyramidal wavefront-based refraction (WFR) measurement and its agreement with dry autorefraction (DR), cycloplegic autorefraction (CR), and subjective refraction (SR) in myopic refractive surgery candidates.
One hundred eighty-nine eyes from 189 participants were evaluated. PERAMIS aberrometry (PERAMIS; SCHWIND eye-tech-solutions, Kleinostheim, Germany), DR, and CR, as well as SR, were completed for all candidates. The repeatability of PERAMIS measurements was assessed, and the Bland-Altman plots were used to test the agreement between different methods.
Repeatability of the PERAMIS aberrometer was very high in the measurement of all refractive elements (Sphere, cylinder, spherical equivalent [M], J0, and J45) (interclass correlation coefficient >0.980 for all). A significant myopic shift was found with WFR compared to CR (0.45 diopter [D]) and SR (0.28 D) ( < 0.05). For the M component, there was a significant difference between WFR and CR ( < 0.05). J0 component measured with WFR was significantly different from SR and CR ( < 0.05). For the J45 variable, all three refraction methods were comparable (all, > 0.05). In M > 5.00 D, a difference of 0.79 D (limit of agreement: -3.50-1.90) was found between WFR and CR.
In lower degrees of myopia, WFR was in good agreement with the manifest autorefraction. WFR, CR, and SR techniques were comparable in measuring astigmatism, especially in oblique astigmatism.
评估基于锥体波前的验光（WFR）测量的可重复性，及其与近视屈光手术候选者的干式自动验光（DR）、睫状肌麻痹验光（CR）和主观验光（SR）的一致性。
对189名参与者的189只眼睛进行评估。所有候选者均完成了PERAMIS像差仪（PERAMIS；德国施温德眼科技术解决方案公司，克莱诺施泰姆）、DR、CR以及SR检查。评估了PERAMIS测量的可重复性，并使用Bland-Altman图来检验不同方法之间的一致性。
PERAMIS像差仪在测量所有屈光成分（球镜、柱镜、等效球镜[M]、J0和J45）时的可重复性非常高（所有组内相关系数均大于0.980）。与CR（0.45屈光度[D]）和SR（0.28 D）相比，WFR发现有显著的近视偏移（P<0.05）。对于M成分，WFR和CR之间存在显著差异（P<0.05）。用WFR测量的J0成分与SR和CR有显著差异（P<0.05）。对于J45变量，所有三种验光方法具有可比性（所有P>0.05）。在M>5.00 D时，WFR和CR之间存在0.79 D的差异（一致性界限：-3.50-1.90）。
在低度近视中，WFR与显然验光结果一致性良好。WFR、CR和SR技术在测量散光方面具有可比性，尤其是在斜向散光方面。
