Fig. 3From: 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 22 y/o man from Group Cwith visual acuity of 20/20 and an axial length of 23.7 mm. The dark green colour of the lens nucleus demonstrates that the strain rate and stiffness are approximately the same as those of the 55 y/o participantBack to article page
