The ability of the human lens to accommodate is mediated by the ciliary muscle and zonule;
the manifest optical power changes depend on the shape and material properties of the …

Photogrammetry is a science and technology which allows quantitative traits to be
determined, ie the reproduction of object shapes, sizes and positions on the basis of their …

Quantifying the full 3-D shape of the human crystalline lens is important for improving
intraocular lens power or sizing calculations in treatments of cataract and presbyopia. In a …

Handbook of Visual Optics offers an authoritative overview of encyclopedic knowledge in the
field of physiological optics. It builds from fundamental concepts to the science and …

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 …

The eye's accommodative mechanism changes optical power for near vision. In
accommodation, ciliary muscle excursion relieves lens tension, allowing it to return to its …

Purpose: Measurement of crystalline lens geometry in vivo is critical to optimize performance
of state-of-the-art cataract surgery. We used custom-developed quantitative anterior …

Purpose: The purpose of this study was to utilize in vivo magnetic resonance imaging (MRI)
and optical modeling to investigate how changes in water transport, lens curvature, and …

Presbyopia is an age-related ocular disorder where accommodative ability declines so that
an individual's focusing range is insufficient to provide visual clarity for near and distance …

An investigation was carried out with the aim of reconstructing the gradient index (GRIN)
profile of human crystalline lenses ex-vivo using optical coherence tomography (OCT) …
