DEVELOPMENTAL DEFORMITIES OF THE CRYSTALLINE LENS. [PDF]
Journal of the American Medical Association, 1908 In the observation brought forward in this paper I propose to show how several forms of congenital cataract are the outcome of arrests of development in the lens at different stages in its formation. I am, naturally, aware that to attribute a condition to an arrest of development offers only a partial explanation of its etiology, leaving the cause of ...

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Age-dependence of the average and equivalent refractive indices of the crystalline lens
, 2014 Lens average and equivalent refractive indices are required for purposes such as lens thickness estimation and optical modeling. We modeled the refractive index gradient as a power function of the normalized distance from lens center. Average index along
