Artificial tears or lubricants is a developing category in pharmaceutical research, due to the permanent increasing incidence of dry eye syndrome caused by the extensive use of personal computers and other gadget screens, associated with global warming and pollution. Considering the role of inflammation in dry eye syndrome, characterized by the production of free radicals, it is imperative to determine which elements are more significant in forming an artificial tear more effectively and more comfortably for the eye state and for the quality of life. Thus, the aim of the present study was to examine the evolution of the total antioxidant capacity of some frequently commercialized artificial tears via the photochemiluminescence method, using an antioxidant capacity of lipid soluble substances procedure, prior and subsequent to the exposure of these therapy agents to some physical agents. This is a preliminary research aiming to evaluate the impact of various environmental factors on these ophthalmic products, to be continued by evaluating whether the effectiveness of these products, in terms of objective examination and patient preference and adherence criteria, is impacted by the conditions of use and storage. Thus, the total antioxidant capacity of the evaluated artificial tear samples after UVC irradiation at 254 nm wavelength was studied, in order to investigate whether their status suffered any change in terms of antioxidant potential. In addition to the findings obtained in the study, some recommendations were also made.

The Effect of Autologous Serum Tears 50% on the Ocular Surface of Patients With Severe Dry Eye Disease due to Sjogren Syndrome: A Prospective, Double-Blind, Randomized, Controlled, Contralateral Eye Study.

January 2025
Department of Ophthalmology, University of Cyprus Medical School, Nicosia, Cyprus.
Purpose: To assess the impact of autologous serum (AS) tears at a 50% concentration on the ocular surface of patients with refractory dry eye disease (DED) because of Sjogren syndrome.
Methods: Twenty eyes of ten patients with severe immune-mediated DED were contralaterally randomized to receive either AS tears 50% or artificial tears between June 2021 and May 2023. Changes in tear stability, ocular surface staining, and in the morphology of the corneal sub-basal nerves were evaluated before treatment and at 1, 2, and 3 months after treatment using objective tests for DED and confocal microscopy.
Circumferential Fiber Augmentation Technique Combined With Transtibial Pullout Repair.

This Technical Note describes a surgical approach that combines circumferential fiber augmentation with transtibial pullout repair for the treatment of medial meniscal posterior root tears. To address the challenge of meniscal extrusion and subsequent joint space narrowing that predisposes to osteoarthritis, this technique uses an artificial ligament to add circumferential collagen fiber reinforcement to improve meniscal extrusion. This integrated approach is designed to address the limitations of conventional tibial pullout repairs by potentially providing better results in preventing meniscal extrusion.

Aims: To understand current clinical management of dry eye disease (DED), based on its perceived severity and subtype by practitioners across the world.
Methods: The content of the anonymous survey was chosen to reflect the DED management strategies reported by the Tear Film and Ocular Surface Society (TFOS) 2 Dry Eye Workshop (DEWS II). Questions were designed to ascertain practitioner treatment choice, depending on the subtype and severity of DED.
Blood component therapy for dry eye disease: a systematic review and network meta-analysis.

Department of Ophthalmology, Zhangye People's Hospital Affiliated to Hexi University, Zhangye, China.
Objective: Blood component therapy has shown promising potential as an emerging treatment for dry eye disease; however, it remains unclear which specific blood component is the most effective. This study aims to compare the efficacy of different blood components in the treatment of dry eye disease through a network meta-analysis, with the goal of providing the latest and most reliable evidence for clinical practice.
Methods: We conducted a systematic search of the PubMed, Web of Science, Cochrane, Embase, and Scopus databases, with the search concluding on June 1, 2024.
