To introduce a novel methodology for subjective refraction based on power vectors with a conventional phoropter.
A conventional phoropter was used to measure power vector components of refraction (M, J and J) directly by using the sphere power (for M measurement) and the cylinder power combined with the Jackson cross-cylinders (for J and J measurements). Conventional subjective refraction was also performed, and this result was mathematically transformed into power vector notation for comparison purposes. Visual acuities with the conventional prescription and the quasi-vector-based prescription were compared.
Refractive error from 40 healthy participants was measured by conventional and quasi-vector-based subjective refraction. No differences were found between methods for any of the power vector components of refraction (p > 0.21 in all cases). The visual acuity achieved with the prescriptions yielded similar values (p = 0.85).
Subjective refraction can be measured directly in power vector notation using a conventional phoropter without any additional adaptation and computation.
介绍一种基于屈光力矢量，使用传统综合验光仪进行主观验光的新方法。
使用传统综合验光仪，通过球镜度（用于测量M）以及柱镜度结合交叉柱镜（用于测量J0和J45）直接测量屈光力矢量分量。同时也进行了传统主观验光，并将结果进行数学转换为屈光力矢量表示法以便比较。比较了传统处方和基于准矢量处方下的视力。
通过传统主观验光和基于准矢量的主观验光测量了40名健康参与者的屈光不正。两种方法在任何屈光力矢量分量上均未发现差异（所有情况下p>0.21）。两种处方下获得的视力值相似（p = 0.85）。
使用传统综合验光仪可以直接以屈光力矢量表示法测量主观验光，无需任何额外的调整和计算。
