Abstract
Two powerful techniques: quasi-elastic light scattering (QELS) and Scheimpflug imaging (SI), are combined to provide simultaneous (within a few seconds) and objective measurements of lens opacity. The sensitivity and performance of the two techniques is evaluated by inducing cold cataract in the lens of a calf eye. The QELS detects the onset of cataractogenesis much earlier while the Scheimpflug imaging system detects it much later.Keywords
