A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

Acta Ophthalmologica, EarlyView.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, EarlyView.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

Can Artificial Intelligence Identify the Ideal Ablation Area for the Patients With Atypical Atrial Flutter? A Proof of Concept Study Using Developed Software

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Catheter ablation for atypical atrial flutter (AFL) is challenging owing to its complex circuit. Consequently, the success rate varies depending on the circuit complexity and the operator's level of experience. Objective This study aimed to create software using artificial intelligence to identify the critical isthmus of atypical ...

Contrast by electron microscopy in thick biological specimens

Journal of Microscopy, EarlyView.
Abstract The contributions of coherent bright‐field phase and incoherent dark‐field amplitude contrast are investigated for thick biological specimens. A model for a T4 phage is constructed and images simulated for both TEM and STEM phase contrast using a multislice code.

Predicting patient‐reported quality of vision through multifocal optics

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To explore the agreement between computationally modelled point‐spread functions (PSFs) and multifocal soft contact lens wearers' descriptions of image quality. Methods In Phase 1, participants were fitted with a single vision soft contact lens (SCL) in the left eye, and four different multifocal (MF) SCLs in the right eye in ...
