The Lens Opacity Meter (LOM) has been developed as a method of quantifying lens opacity. It was compared both with a photographic system and with measured visual acuity. The LOM is a simple system to operate and requires minimal training. LOM readings were correlated with the presence and severity of nuclear opacity and also total cataract grade. It also showed a correlation with visual acuity. LOM readings were not useful in documenting the presence or severity of cortical or posterior subcapsular opacity, and in these cases there was considerable variation in the LOM readings. These data suggest that the LOM may be of limited value as a simple screening test, but it has limited use in discriminating between various types of severity of opacities.
晶状体混浊度仪（LOM）已被开发出来作为一种量化晶状体混浊的方法。它与摄影系统以及测量的视力进行了比较。LOM是一个操作简单的系统，只需极少的培训。LOM读数与核性混浊的存在和严重程度以及白内障总分级相关。它还与视力相关。LOM读数对于记录皮质性或后囊下混浊的存在或严重程度并无用处，在这些情况下，LOM读数存在相当大的差异。这些数据表明，作为一种简单的筛查测试，LOM的价值可能有限，但在区分不同类型混浊的严重程度方面用途有限。
