Computational simulation of aqueous humour dynamics in the presence of a posterior-chamber versus iris-fixed phakic intraocular lens. [PDF]
PLoS ONE, 2018 PURPOSE:To compare aqueous humour (AH) dynamics in the presence of a precrystalline (Implantable Collamer Lens®; ICL) or iris-fixed (Artiflex®) phakic intraocular lens (PIOL).

Delhi Journal of Ophthalmology, 2022 Microspherophakia usually presents with various systemic and ocular features, and is rarely as an isolated incident. In this manuscript, we have reported a rare occurrence of bilateral isolated microspherophakia with unilateral total anterior luxation of

THE AUTOLYSIS OF THE CRYSTALLINE LENS [PDF]
Journal of the American Medical Association, 1911 In the study of traumatic cataract and the needling operation, I was struck with the very scant description of the manner in which the lens becomes opaque and the causes for its opacity and final absorption. Parsons 1 states that after exposure of the lens fibers to the action of the aqueous they swell up, become opaque, protrude through the capsular ...

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency
Advanced Materials, EarlyView.This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films
Advanced Materials, EarlyView.ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

A rare case of traumatic posterior phacocele with retinal detachment
Indian Journal of Ophthalmology, 2016 Dislocation of crystalline lens into the anterior subconjunctival or subtenon′s space is a rare but known complication of blunt trauma. Dislocation into the posterior subtenon′s space is even rarer and can be associated with a complication such as occult

Advanced Materials, EarlyView.Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.
