We conducted a reproducibility study on the Kowa Early Cataract Detector, a laser light scattering spectroscope that determines the diameter of particles within the lens and designed to quantify changes in particle size in early cataracts. We found good reproducibility in the nuclear region (where changes are homogeneous), but found poor reproducibility in the cortical region (where changes are heterogeneous). We advise careful evaluation of other similar devices before extensive use.
