Review of clinical outcomes of a cationic emulsion tear substitute in patients with dry eye disease

open access: yesActa Ophthalmologica, Volume 102, Issue 4, Page 382-390, June 2024.
Abstract First‐line options for the treatment of dry eye disease (DED) rely on artificial tears (ATs), among which cationic emulsion (CE)‐based ATs have been developed in order to mimic the healthy tear film for an improved restoration of the ocular surface homeostasis. In this review, we describe the outcomes reported in several studies, assessing the

Efficacy of far infrared functional glasses in the treatment of meibomian gland dysfunction‐related dry eye

open access: yesMedComm, Volume 5, Issue 4, April 2024.
In this clinical trial, 61 patients with MGD‐related DED wore FIR‐functional eyeglasses throughout the day and underwent a comprehensive eye assessment at the trial's end. Significant improvements were observed in the symptoms, clinical signs, and meibomian gland function of patients with MGD‐related DED.

Analytical method to find the optimal parameters for gas detectors based on correlation spectroscopy using a Fabry-Perot interferometer [PDF]

open access: yes, 2007
Several designs of infrared sensors use a Fabry-Perot Interferometer (FPI) to modulate the incident light. In this work we analyse the particular case where the FPI fringes are matched with very well defined ro-vibrational absorption lines of a target ...

Full-field optical coherence tomography using a fibre imaging bundle [PDF]

open access: yes, 2006
An imaging fibre bundle is demonstrated for spatially-multiplexed probe beam delivery in OCT, with the aim of eliminating the mechanical scanning currently required at the probe tip in endoscopic systems.

Clinical Accuracy of an Advanced Corneal Topographer with Tear-Film Analysis in Functional and Structural Evaluation of Dry Eye Disease

open access: yes, 2020
Purpose: Dry eye disease (DED) is a common condition that significantly lowers the quality of life. As the disease grows more prevalent, multiple commercial instruments have been developed to measure the ocular surface of dry eyes, but no single device ...
