Scheimpflug imaging of the post lens tear film during contact lens wear [PDF]

, 2014
A new imaging methodology is described to visualise the post lens tear film (PLTF) during contact lens wear. A rotating-Scheimpflug camera in combination with sodium fluorescein allows evaluation of the PLTF for different contact lens modalities,

Reconstruction of deep and perforating corneal defects in dogs—A review (Part II/III): Biomaterials and keratoprosthesis

Veterinary Ophthalmology, Volume 28, Issue 2, Page 532-542, March 2025.
Abstract The surgical reconstruction of severe corneal ulcers is a common and crucial component of the clinical practice of veterinary ophthalmology. Numerous surgical techniques are used in dogs for corneal reconstruction, and these techniques may be categorized by the material used to repair the corneal lesion.

Mild Topographic Abnormalities that Become More Suspicious on Scheimpflug Imaging

, 2009
Purpose Although several screening methods exist, postoperative corneal ectasia after refractive surgery is a severe complication. One possibility for this might be the fact that screening methods may fail in detection of preoperative risk factors such ...

Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype

Diabetes, Obesity and Metabolism, Volume 28, Issue 11, Page 9809-9818, November 2026.
ABSTRACT Context Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one‐third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro‐metabolic phenotype involving the retina,

Developing Soft Interconnected Microchannel Network for 2D Skin‐Like Actuator

Advanced Science, Volume 13, Issue 60, 28 October 2026.
A soft interconnected network of microchannels is proposed to develop new pneumatic actuators for future bio‐inspired soft robots. Simultaneous stimulation of this network generates regional asymmetric strains in walls of microchannels whose interaction across the entire surface leads to bending curvatures in multidimensions.

One‐Year Results of Accelerated Transepithelial Corneal Cross‐Linking for Progressive Keratoconus: A Prospective Interventional Study

Eye &ENT Research, Volume 3, Issue 3, Page 168-174, September 2026.
ABSTRACT Background Keratoconus is a progressive corneal ectatic disorder. Accelerated transepithelial corneal cross‐linking (ATE‐CXL) aims to halt progression while preserving the epithelium, but evidence on its 12‐month efficacy requires further evaluation.
