Laser‐Assisted Micropatterned 3D Printed Scaffolds with Customizable Surface Topography and Porosity for Modulation of Cell Function

Advanced Healthcare Materials, Volume 14, Issue 3, January 27, 2025.
This study shows that integrating 3D printing with femtosecond laser engraving enables the precise formation of surface patterns on biomaterial scaffolds. The laser‐engraved micropatterns, such as microgrooves and micropits on poly(ε‐caprolactone) (PCL) scaffolds, retain their shape for at least 14 d in aqueous environments, significantly enhancing ...

Optical Evaluation of New Designs of Multifocal Diffractive Corneal Inlays

Journal of Ophthalmology, Volume 2019, Issue 1, 2019., 2019
Purpose. To assess the imaging properties of two different designs of a new concept of corneal inlays whose working principle is based on diffraction. Methods. The quality of the retinal images provided by Diffractive Corneal Inlays (DCIs) was evaluated theoretically in comparison with Small Aperture Corneal Inlay (SACI). ZEMAX OpticStudio software was

Human eyes do not need monochromatic aberrations for dynamic accommodation

Ophthalmic and Physiological Optics, Volume 37, Issue 5, Page 602-609, September 2017., 2017
Abstract Purpose To determine if human accommodation uses the eye's own monochromatic aberrations to track dynamic accommodative stimuli. Methods Wavefront aberrations were measured while subjects monocularly viewed a monochromatic Maltese cross moving sinusoidally around 2D of accommodative demand with 1D amplitude at 0.2 Hz.

Propagation length enhancement of surface plasmon polaritons in gold nano‐/micro‐waveguides by the interference with photonic modes in the surrounding active dielectrics

Nanophotonics, Volume 6, Issue 5, Page 1109-1120, March 2017., 2017
Abstract In this work, the unique optical properties of surface plasmon polaritons (SPPs), i.e. subwavelength confinement or strong electric field concentration, are exploited to demonstrate the propagation of light signal at 600 nm along distances in the range from 17 to 150 μm for Au nanostripes 500 nm down to 100 nm wide (30 nm of height ...

Impact of stimulant treatment on refractive errors and pupil diameter in attention deficit hyperactivity disorder

Acta Ophthalmologica, Volume 102, Issue 5, Page e842-e850, August 2024.
Abstract Purpose The relationship between attention deficit hyperactivity disorder (ADHD) and visual impairment remains poorly understood, and the impact of visual impairment on the development of ADHD is uncertain. The aim of this study was to investigate the refractive profile and ocular biometric characteristics in patients diagnosed with ADHD and ...

Assessing neophyte response to daily disposable silicone hydrogel contact lenses: A randomised clinical trial investigation over one month

Ophthalmic and Physiological Optics, Volume 44, Issue 5, Page 876-883, July 2024.
Abstract Objective This randomised clinical trial assessed the impact on symptoms, tear film dynamics and ocular surface integrity of daily disposable silicone‐hydrogel contact lenses (CLs) over a month, paying special attention to lid wiper epitheliopathy (LWE) and its implications for CL discomfort.
