In vivo Observation of the Crystalline Lens Capsule

Ophthalmic Research, 1988
The crystalline lens capsules of eye bank eyes, intraocular lens (IOL)-inserted eyes and those of monkey and rabbit eyes were observed in vivo and/or in vitro through a specular microscope or Scheimpflug slit images in combination with new image-processing techniques and scanning electron microscopy. Shagreen patterns seen in both human and animal eyes

Characterizing human decellularized crystalline lens capsules as a scaffold for corneal endothelial tissue engineering [PDF]

Journal of Tissue Engineering and Regenerative Medicine, 2018
The idea of transplanting a sheet of laboratory-grown corneal endothelium dates back to 1978; however, the ideal scaffold is still lacking. We hypothesized that human crystalline lens capsules (LCs) could qualify as a scaffold and aimed to characterize the properties of this material for endothelial tissue engineering. LCs were isolated from donor eyes,

Proteomic analysis of the bovine and human ciliary zonule [PDF]

, 2016
PURPOSE: The zonule of Zinn (ciliary zonule) is a system of fibers that centers the crystalline lens on the optical axis of the eye. Mutations in zonule components underlie syndromic conditions associated with a broad range of ocular pathologies ...

Radiocarbon dating of the human eye lens crystallines reveal proteins without carbon turnover throughout life. [PDF]

PLoS ONE, 2008
BackgroundLens crystallines are special proteins in the eye lens. Because the epithelial basement membrane (lens capsule) completely encloses the lens, desquamation of aging cells is impossible, and due to the complete absence of blood vessels or ...

Age-Related True Exfoliation of the Lens Capsule: Phacoemulsification Surgery Results

Case Reports in Ophthalmology, 2015
Historically associated with glassblowers, true exfoliation of the crystalline lens involves a splitting or delamination of the capsule. We reviewed the phacoemulsification records of a single surgeon for patients with true exfoliation of the lens ...

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.

A medieval fallacy: the crystalline lens in the center of the eye. [PDF]

, 2016
ObjectiveTo determine whether, as most modern historians have written, ancient Greco-Roman authors believed the crystalline lens is positioned in the center of the eye.BackgroundHistorians have written that statements about cataract couching by Celsus ...

The importance of parameter choice in modelling dynamics of the eye lens [PDF]

, 2017
The lens provides refractive power to the eye and is capable of altering ocular focus in response to visual demand. This capacity diminishes with age.
