Fig. 1From: In vivo ultraosound elastographic evaluation of the age-related change of human lens nuclear stiffnessa to c Three images taken repeatedly with the ultrasound echolucency (right) and elastic (left) mode of the right eye of a 75 y/o man from Group A with a visual acuity of 20/20 and an axial length of 23.0 mm. The deep blue colour of the lens nucleus demonstrates that the strain rate is low, and therefore, the lens nucleus is stiffBack to article page
