A Study of Full-Spectrum Screen Lighting for Reducing Screen-Related Eye Fatigue and Dry Eye

This study will evaluate whether full-spectrum screen bar lighting can reduce eye fatigue and dry eye symptoms after a standardized screen task. Prolonged screen use is common in daily work and study and may cause blurred vision, eye soreness, dryness, headache, and reduced attention. Light environment may be one way to improve visual comfort during screen use, but more controlled clinical evidence is needed. In this randomized, parallel-group controlled study, 112 healthy adult participants will be assigned to either a full-spectrum screen bar lighting group or a brightness-matched control group without screen bar lighting. Participants in both groups will complete an approximately 2-hour standardized screen task in a controlled laboratory environment. The study will compare changes before and after the task in objective and subjective measures of visual fatigue and dry eye, including critical flicker fusion frequency, visual fatigue questionnaire scores, eye movement and blinking parameters, pupil parameters, tear film-related measurements, and dry eye symptom scores. Safety and discomfort during the study will also be recorded.

Temporary Tear Duct Filling With Hyaluronic Acid Gel and Assessment of Dry Eye Disease (DED) After Bilateral Cataract Surgery

Dry eye disease can occur or worsen after cataract surgery and may cause ocular discomfort and reduced visual quality. Standard treatment commonly includes artificial tear eye drops, which provide temporary lubrication. Temporary occlusion of the tear drainage system may offer an alternative approach by increasing tear retention and improving tear film stability. This prospective, randomized, double-blind, inter-eye study will evaluate the use of LACRIFILL® Canalicular Gel, a crosslinked hyaluronic acid gel placed in the tear drainage system, in patients who have undergone bilateral cataract surgery. Treatment allocation will be randomized at the eye level within each participant. One eye will be assigned to treatment with LACRIFILL®, while the fellow eye will serve as the control and receive standard care with artificial tear eye drops. The study will compare the development and severity of dry eye disease between the randomized treatment and control eyes. The main outcome will be tear production measured by the Schirmer Test 1 one month after treatment. Additional assessments will include tear film stability, ocular surface findings, anterior segment imaging, visual quality, dry eye symptoms, use of artificial tears, and treatment-related safety outcomes during a three-month follow-up period.

Comparing Efficacy of Autologous Serum Eye Drops With and Without Insulin in Autoimmune Dry Eye.

Introduction: Dry Eye Disease (DED) of autoimmune origin is often severe and resistant to conventional treatments, necessitating alternative therapeutic options. Autologous Serum Eye Drops (ASED) have gained recognition for their biochemical and biomechanical properties, which closely mimic those of human tears. These properties make ASED an effective treatment for DED. Furthermore, topical insulin has demonstrated anti-inflammatory effects and promotes epithelial cell proliferation, differentiation, and migration, all of which contribute to maintaining ocular surface stability. As a result, insulin may serve as a valuable adjunct in treating moderate to severe autoimmune DED. Purpose: This study aims to assess and compare the effectiveness of autologous serum eye drops (group 1) and autologous serum eye drops combined with insulin (group 2) in improving the clinical signs and symptoms of moderate to severe DED in patients with autoimmune diseases, particularly those with Sjögren's Syndrome.

Microbiome-Focused Food Supplement for Evaporative Dry Eye Due to Meibomian Gland Dysfunction

Dry eye disease (DED) is a common chronic condition characterized by ocular surface discomfort and tear film instability. Evaporative DED associated with meibomian gland dysfunction (MGD) is a frequent phenotype and is often driven by inflammatory mechanisms. This randomized, double-blind, placebo-controlled trial evaluates whether an oral microbiome-focused food supplement improves dry eye symptoms and objective clinical signs compared with placebo over 8 weeks in adults with moderate evaporative DED due to MGD.

Autologous Serum Tears With Hyaluronate vs Balanced Salt Solution for Moderate-to-Severe Dry Eye

This study aims to find out whether adding sodium hyaluronate, a moisturizing ingredient commonly found in artificial tears, makes autologous serum eye drops more effective for treating moderate-to-severe dry eye disease. Each participant will use one version of the drops in one eye and the standard version in the other eye. The goal is to see if the new combination provides better relief, comfort, and eye surface healing compared to the traditional formulation.

Cord Blood Platelet Poor Plasma Eye Drops

Dry eye disease (DED) is a prevalent ocular condition characterized by the disruption of the ocular surface's homeostasis. It affects a significant portion of the population, particularly women and older individuals. The impact of DED on the healthcare system and patients' quality of life is substantial, with approximately 30 million adult patients (14.5%) reporting DED symptoms in the US. Global mapping studies have shown that DED prevalence ranges from 5% to 50% of the population. While chronic instillation of artificial tears is the main treatment strategy for DED, it is often ineffective in moderate to severe cases associated with corneal inflammation. Innovative therapeutic approaches using human serum and platelet derivatives have shown promising results in tear substitution. Umbilical cord blood plasma, which contains natural tissue regenerative and immunomodulatory factors, has demonstrated positive effects on corneal epithelial cells and clinical efficacy in observational studies. This study aims to develop a randomized clinical trial protocol to compare the clinical efficacy of artificial tears (control arm) and human platelet poor plasma from umbilical cord blood (treatment arm) in the treatment of DED. The results of this clinical trial will contribute to understanding the clinical efficacy of umbilical cord blood plasma eye drops compared to artificial tears in the treatment of moderate to severe DED.

Study of Proteomic Factors in Patients With Severe Dry Eye Syndrome Treated With Autologous Serum Eye Drops.

Dry eye syndrome is a multifactorial pathology of the ocular surface. Epidemiological studies report a prevalence of 15% in adults aged between 50 and 95. Depending on the severity of the disease, different treatment strategies may be proposed. The use of autologous serum eye drops (AS) represents an interesting therapeutic alternative for the most severe forms of the disease, due to the serum's composition, which is similar to that of tears. The mechanism of action of AS is still controversial, but is probably multifactorial and seems to be based on growth factors, vitamin factors and anti-inflammatory factors. The clinical response of patients could be dependent on the protein composition of the eye drops. The investigators are aiming to highlight a difference in serum protein composition that could explain the differences in clinical response between patients treated with autologous serum eye drops and to identify the proteins that would be involved in a clinical response or non-response.

Effect of Dry Eye Treatment on Corneal Astigmatism Measurements

This prospective single-center study evaluates the effect of dry eye disease and short-term ocular surface treatment on the agreement and repeatability of corneal astigmatism measurements in patients with age-related cataract. Participants undergoing preoperative cataract evaluation are classified into a control group or a dry eye disease group according to ocular surface symptoms and objective tear film findings. All participants undergo ocular surface assessment and repeated corneal measurements using three commonly used devices: IOLMaster 700, Pentacam AXL, and iTrace Prime. Measurements include keratometric corneal astigmatism, total corneal astigmatism, and vector components of astigmatism. Patients with dry eye disease receive 0.3% sodium hyaluronate eye drops four times daily for 2 weeks, after which ocular surface assessment and device measurements are repeated. The primary objective is to determine whether dry eye disease reduces interdevice agreement and test-retest repeatability of corneal astigmatism measurements, and whether short-term ocular surface treatment improves measurement stability. Interdevice agreement is assessed using Bland-Altman analysis, and repeatability is evaluated using within-subject standard deviation, test-retest repeatability, and intraclass correlation coefficient.
