furthermore , the data can be quickly processed to yield indices which can be used to characterize the cataract : 1 ) the integral of an axial densitogram as a criterion of average lens opacity , and 2 ) the difference between the linear regressions of the densitograms of the anterior and posterior lens halves as a criterion of cataract form ( e.g. , nuclear vs. cortical cataract ) .
