Age-Related Changes to the Three-Dimensional Full Shape of the Isolated Human Crystalline Lens
Investigative Ophthalmology and Visual Science, 2020 Purpose Studying the full shape crystalline lens geometry is important to understand the changes undergone by the crystalline lens leading to presbyopia, cataract, or failure of emmetropization, and to aid in the design and selection of intraocular ...

Crystalline lens imaging with a slit-scanning system [PDF]
, 2011 [Introduction] The human crystalline lens plays a fundamental role on the retinal image quality. The ability of the lens to change its shape and, consequently, the total refractive power of the eye, during accommodation, enables one to focus objects at a

Effect of Tropicamide on crystalline Lens rise in low-to-moderate myopic eyes
BMC Ophthalmology, 2020 Background Cycloplegics have been reported to induce changes in the lens thickness. However, the studies of correlation between cycloplegia and the lens position are limited. This study aims to investigate changes in crystalline lens rise (CLR) and other

Hardness of porous nanocrystalline Co-Ni electrodeposits [PDF]
, 2013 The Hall-Petch relationship can fail when the grain size is below a critical value of tens of nanometres. This occurs particularly for coatings having porous surfaces.

Observing 3-hydroxyanthranilate-3,4-dioxygenase in action through a crystalline lens
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance NAD+ plays a critical role in redox-linked biological reactions as a cofactor or substrate. The knowledge of its de novo biosynthesis in mammals and certain bacteria is incomplete due to missing information of a nonheme iron dioxygenase ...

Finite element study of the accommodation behaviour of the crystalline lens after fs-laser treatment [PDF]
, 2013 With aging the ability of the crystalline lens to adapt to different viewing distances decreases. Until now there is no satisfying treatment available.
