A clinical trial was undertaken to determine whether a commercially available lens opacity meter (LM701), which measures backward scattered light from the lens, provides reliable clinical information about the effect of lens opacities on visual acuity. At the 0.001 level of probability we found a significant relationship between the lens opacity meter reading and both the Snellen acuity and patient's age. For a given individual there was also a relationship between the difference in the lens opacity readings between eyes and the difference in the Snellen acuities. We could not demonstrate a relation between the lens opacity reading and either the refractive error, pupil size, or near visual acuity at this level of significance.
进行了一项临床试验，以确定一种市售的晶状体混浊度仪（LM701）是否能提供关于晶状体混浊对视力影响的可靠临床信息，该仪器通过测量晶状体向后散射光来进行检测。在0.001的概率水平下，我们发现晶状体混浊度仪读数与斯内伦视力表视力及患者年龄之间存在显著关系。对于给定个体，双眼晶状体混浊度读数的差异与斯内伦视力表视力的差异之间也存在关系。在这一显著性水平下，我们未能证明晶状体混浊度读数与屈光不正、瞳孔大小或近视力之间存在关联。
