Structural changes of the rabbit retina after 14-days tamponade of the vitreal cavity with perfluoro-organic compounds

Journal of Ophthalmology, 2015
Introduction. Perfluoro-organic compounds (PFOC) have valuable qualities for vitreoretinal surgery and their application for short-term tamponade could expand indications for preoperative treatment and improve its results.

Flow Behavior of Heavy Silicone Oil During Eye Movements

Investigative Ophthalmology & Visual Science, 2014
Currently there are various heavy silicone oil (HSO) tamponade agents available for treating inferior retinal diseases. Most of these HSO agents are either homogeneous liquids or a mixture of two components. Variations in their emulsification rates in vivo have been reported. In this study, we investigated their flow behaviors during eye-like movements.

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Upscaling the Fabrication of Rod‐Shaped Microgels: A Microfluidic Method Combining Step‐Emulsification With Consecutive Droplet Confinement in Parallelized Microchannels

Advanced Materials, EarlyView.
A microfluidic method is presented which enables parallelized fabrication of rod‐shaped microgels, based on step‐emulsification (SE) droplet generation and subsequent droplet distribution and confinement, combined in a single device. Microgel rods are fabricated in parallel at different flow rates based on two light‐mediated crosslinking chemistries ...

A Multifunctional Ionograsper Enabling Ion‐Redistribution Proximity Sensing and Structural‐Reconfiguration‐Driven Bidirectional Actuation

Advanced Materials, EarlyView.
A solid‐state ionic actuator integrates sensing, actuation, and memory within one material. A brief UV pulse induces long‐lasting deformation via coupled network rearrangement, dehydration, and rehydration, while ionic redistribution enables self‐powered sensing, supporting multifunctional, energy‐efficient soft robotic functions without continuous ...

Effect of PFCL versus heavy silicone oil on the structure and functional state of the rabbit retina

Journal of Ophthalmology, 2016
Background: The use of perfluorocarbon liquids (PFCL) and heavy silicone oil (HSO) for post-vitrectomy tamponade would potentially widen the range of indications for and improve outcomes of vitreoretinal surgery.
