In 50 eyes with nuclear cataract, posterior subcapsular cataract and cortical cataract and 34 normal eyes, the amount of scattered light was determined using the Opacity Lensmeter 701 to determine its accuracy in distinguishing between clear and cataractous lenses. Taking as a basis the manufacturer's statement that normal lenses show Opacity Lensmeter readings of less than 25 and that cataractous lenses show Opacity Lensmeter readings of more than 30, 94% of the nuclear cataract cases, 62% of the posterior subcapsular cases and 66% of the cortical cataract cases were identified as being pathologically opaque. Of the normal eyes, 88% had an Opacity Lensmeter reading of less than 25. Among the types of cataract examined, a significant linear relationship (P < 0.05) between visual acuity loss due to cataract and scattered light measurements could be found only in eyes with nuclear cataract, with the individual results heavily scattered around the linear regression. In the case of nuclear cataracts, measuring scattered light with the Opacity Lensmeter is suitable for making general statements on visual loss due to cataract for a whole group of patients. However, in individual cases the results can only be used together with other clinical examinations.
在50只患有核性白内障、后囊下白内障和皮质性白内障的眼睛以及34只正常眼睛中，使用701型不透明度晶状体计测定散射光量，以确定其在区分透明晶状体和白内障晶状体方面的准确性。以制造商的声明为依据，即正常晶状体的不透明度晶状体计读数小于25，白内障晶状体的不透明度晶状体计读数大于30，94%的核性白内障病例、62%的后囊下白内障病例和66%的皮质性白内障病例被确定为病理性混浊。在正常眼睛中，88%的不透明度晶状体计读数小于25。在所检查的白内障类型中，仅在核性白内障患者的眼中发现白内障导致的视力丧失与散射光测量之间存在显著的线性关系（P<0.05），个体结果在直线回归周围严重分散。对于核性白内障，用不透明度晶状体计测量散射光适用于对一组患者因白内障导致的视力丧失做出一般性陈述。然而，在个别情况下，结果只能与其他临床检查一起使用。
