Morphology of age-related cuneiform cortical cataracts: the case for mechanical stress
Acta Ophthalmologica, 08/21/2012
Michael R et al. – Because the lens cortex and nucleus have different viscoelastic properties in young and old lenses, authors hypothesize that external forces during accommodation cause shear stress predominantly in this border zone. The location of the described changes suggests that these mechanical forces may cause fiber disorganization, small cortical opacities, and ultimately, cuneiform cataracts.
