目得：为了评估三个波前分析仪与一个有效的双目开放式自动验光仪在确定非睫状肌麻痹眼屈光不正的准确性，方法：80只眼睛进行了检查，使用SRW-5000开放式红外自动验光仪，并在随机序列中，三个波前分析仪：1）OPD-Scan（NIDEK，Gamagori，日本），2）WASCA（Zeiss/Meditec，Jena，德国），和3）Allegretto（WaveLight Laser Technologies AG，埃尔兰根，德国）。受试者为健康成人（19名男性和21名女性;平均年龄：20.8 ± 2.5岁）。屈光不正范围为+1.5至-9.75屈光度（D）（平均值：+1.83 +/- 2.74 D），柱镜高达1.75 D（平均值：0.58 +/- 0.53 D）。由一名检查员在没有抗胆碱能药物的情况下每台仪器采集三个读数。结果：SRW-5000与波前像差分析仪的等效球镜屈光度（OPD-Scan，r = 0.959，P < 0.01）呈正相关（P < 0.01），SRW-5000与波前像差分析仪的等效球镜屈光度（OPD-Scan，r = 0.959，P < 0.01）呈负相关（P < 0.01）。
PURPOSE: To assess the accuracy of three wavefront analyzers versus a validated binocular open-view autorefractor in determining refractive error in non-cycloplegic eyes.METHODS: Eighty eyes were examined using the SRW-5000 open-View infrared autorefractor and, in randomized sequence, three wavefront analyzers: 1) OPD-Scan (NIDEK, Gamagori, Japan), 2) WASCA (Zeiss/Meditec, Jena, Germany), and 3) Allegretto (WaveLight Laser Technologies AG, Erlangen, Germany). Subjects were healthy adults (19 men and 21 women; mean age: 20.8 +/- 2.5 years). Refractive errors ranged from +1.5 to -9.75 diopters (D) (mean: +1.83 +/- 2.74 D) with up to 1.75 D cylinder (mean: 0.58 +/- 0.53 D). Three readings were collected per instrument by one examiner without anticholinergic agents. Refraction values were decomposed into vector components for analysis, resulting in mean spherical equivalent refraction (M) and J(0) and J(45) being vectors of cylindrical power at 0 degrees and 45 degrees, respectively.RESULTS: Positive correlation was observed between wavefront analyzers and the SRW-5000 for spherical equivalent refraction (OPD-Scan, r = 0.959, P
