Comparative Proteomic Analysis of Aqueous Humor, Anterior Lens Capsules, and Crystalline Lenses in Different Human Cataract Subtypes Versus Healthy Controls [PDF]

Proteomes
Background: The aim of this study is to investigate the pathophysiology of cataract by analyzing signaling pathways in three sample types obtained from four different lens groups: age-related (ARC), diabetic (DC), post-vitrectomy cataract (PVC) and clear

“Best Pick and Hold” with “Wrap and Roll” technique for extreme subluxated crystalline lens [PDF]

Indian Journal of Ophthalmology
Background: A severely subluxated crystalline lens refers to significant displacement of the eye’s natural lens from its normal position, often due to zonular weakness or rupture.[1] This condition can result from trauma, connective tissue disorders like

The lens capsule significantly affects the viscoelastic properties of the lens as quantified by optical coherence elastography

Frontiers in Bioengineering and Biotechnology, 2023
The crystalline lens is a transparent, biconvex structure that has its curvature and refractive power modulated to focus light onto the retina. This intrinsic morphological adjustment of the lens to fulfill changing visual demands is achieved by the ...
