Paper Abstract

Speckle-modulated laser fields arising at in vitro measurements of different types of human cataractous lenses have been investigated experimentally. Computer analysis of digital images has allowed to estimate of destruction of the spatial coherence of a laser beam scattered by a turbid lens. Applied speckle-technologies have permitted the range of retinal angular resolution to be estimated with the help of laser retinometer at the stage of preoperative cataract diagnosis. Effect of saturation of the average speckles size in multiple-scattering biotissues gives good opportunities to determine preoperative retinal visual acuity for any type of cataracts in vivo.
