Single-Arm Study of a Treatment for Dry Eye in People Who Struggle to Wear Contact Lenses

This research study is to see if using Lacrifill is safe, easy to use, and helpful for people who wear contact lenses but can't wear them comfortably for long. Specifically, the study aims to determine whether regular use of Lacrifill over a 2-3 month period can help people wear their contacts longer without discomfort and reduce signs and symptoms of dry eye.

Study of Blinking as a Function of Tear Film Quality

The goal of this study is to better understand how eye blinking behavior is linked to the stability of the tear film, in adults aged 18 to 65 years, with or without symptoms of dry eye. The main questions are: * Do the results of a New Blink Task reflect tear film stability ? * How are the blink related metrics in relation with each other? Researchers will compare two groups of participants-those without dry eye symptoms and those with dry eye symptoms-to see if blinking measures differ between them and whether these measures relate differently to tear film quality. Participants will: * Answer a questionnaire about dry eye symptoms * Have their visual correction measured (if they wear glasses) * Undergo non-invasive assessments of tear film quality using an imaging device * Complete three types of blink tasks, each repeated three times, including measurements of blinking and of tear film stability

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.

Penn SICCA Follow-up Study

This study will involve the collection of follow-up data for patients who previously participated in the Sjogren's International Clinical Collaborative Alliance (SICCA) study at the University of Pennsylvania. Clinical data and specimens will be collected from subjects with objective evidence of dry eye who were or were not diagnosed with Sjogren's syndrome at the time of their initial participation in the SICCA study. Specimens will be collected from participants which will include tears, saliva, whole blood, serum, DNA and possible labial minor salivary gland biopsies when indicated. All individuals will participate in a standard evaluation protocol including an oral, ocular and physical examination, objective tests for dry eyes and dry mouth and, whenever necessary, a labial minor salivary gland biopsy. The biopsy requirement is waived for those who have already had positive lip biopsies in the past.

Telemedicine for Evaluating Dry Eye Disease (DED) Using a Mobile Phone-Attached Portable Automatic Ocular Surface Imaging Device (PAOSID): A Patient-Operated Diagnostic and Continuous Ocular Surface Monitoring (COSM) System

Dry eye disease (DED) is a common eye condition that is becoming more widespread. Detecting it early, keeping track of its progression, and following up regularly can help protect vision and prevent serious complications. However, due to a shortage of ophthalmologists, limited access to eye care services, and disparities in care quality, many patients receive infrequent or insufficient clinical consultations. To address these needs, a portable automatic ocular surface imaging device (PAOSID) that attaches to a mobile phone has been developed. This device uses three types of light including white, infrared, and cobalt blue light to capture clear images and videos of the eye's surface. It also has a smart system that automatically takes high-quality images, allowing patients to use it at home independently. This device may help detect early signs of DED and monitor eye health more easily.

Comparing Tear Proteomics Profile in Dry Eye Disease pre-and Post-treatment With Low Level Light Therapy

The purpose of this research study is to understand the mechanism of action of low level light therapy and also potentially yield markers associated with good treatment response. Low-level light therapy is light-based treatment delivered through advance eye-light device. This therapy uses light energy to provide energy to the meibomian gland cells to slow down age-ing, improve tear stability and reduce inflammation.

SAS 1: Develop Ocular Disease (OSD) Diagnostic, Algorithms, and Management Protocols for Cataract Surgery

Patient: Tear film issues resulting in poor visual outcomes are a major cause of dissatisfaction after cataract surgery. There is no universal best preoperative algorithm for managing the ocular surface prior to surgery. Industry: Recent advances in tear/cornea imaging and refractive cataract surgery such as multifocal intraocular lenses will be advantageous to patients only if tear film issues can be addressed. Society: Cataract surgery is the most common ophthalmic surgery done in Singapore and worldwide. Improving vision by attending to tear film problems improves quality of life.

Evaluate the efficacy and safety of ocular surface microbiota transplantation as an adjunctive therapy for dry eye, and explore its impact on the structure of the ocular surface microbiota.

Eyelid Closure in Keratometry

Cataract surgery is one of the most common performed surgeries in the world. While in the early beginnings of cataract surgery, visual rehabilitation was the main goal of the procedure, refractive outcome and subsequent relative spectacles independency is gaining increasing importance in patients' demands. Due to the improvements in measurement techniques and prediction formulas, the prediction of postoperative refraction is possible with high accuracy. However, there are still some sources of error that lead to deviations of predicted postoperative refraction. For instance, it was shown that tear film osmolarity, an established biomarker for dry eye disease (DED), plays an important role in preoperative precision of keratometry measurements. Keratometry, the measurement of corneal curvature, is an important part of preoperative biometry. Errors in preoperative keratometry measurements lead to nearly one-to-one deviations from the predicted refraction. Therefore, proper keratometry measurements are a key element in intraocular lens (IOL) power calculations. To counteract the issue of DED in preoperative biometry, the principle of using lubricating eye drops before ocular biometry has been investigated and it was shown that the use of ocular lubricants may lead to increased variability of keratometry measurements. From our clinical observations, another possible mechanism to improve keratometry is eyelid closure for some minutes. In contrast to the long-term use of ocular lubricants to stabilize the tear film, eyelid closure is an easy and fast intervention to possibly improve the precision of keratometry measurements. Additionally, a clinical trial investigating the usage of lubricating eye drops for two weeks found no improvement of variability of keratometry in DED patients. Therefore, this study aims to investigate the effect of eyelid closure on the quality index of keratometric measurements in patients with a warning for the quality of keratometric measurements. For this purpose, a single study day including 4 repeated measurements (2 without and 2 with lid closure for 3 minutes) using an ocular biometer (IOLMaster700) will be performed.

To determine the efficacy of switching participants who are being treated with Xiidra to acoltremon 0.003%. Hypothesis: Switching to acoltremon 0.003% will greatly improve the signs and symptoms of participants who were being treated with Xiidra at 28 days post-treatment compared to baseline.

Impact of TRYPTYR on a Patient's Quality of Life and Ability to Perform Work

This 1-month, 3-visit study will be conducted at the Southern College of Optometry (Memphis, TN), Kannarr Eye Care, LLC (Pittsburg, KS) and Complete Eye Care of Medina (Minneapolis, MN). Adults ≥18 years of age who have been diagnosed with DED for at least 6 months and who are currently symptomatic (Eye Dryness VAS Score ≥40) will be recruited. Subjects will have an abnormal Schirmer test of \<10 mm/5 min. Subjects will also be required to score ≤70 on the IDEEL Quality of Life (QoL) Work domain to ensure that their DED symptoms are significantly impacting their ability to do work.9 Subjects will be required to have corrected distance visual acuity of 20/32 (0.2 logMAR) or better.

Switching From Restasis to TRYPTYR

Switching to acoltremon 0.003% will significantly improve the signs and symptoms of participants who were being treated with Restasis at 28 days post-treatment compared to baseline. Dry eye disease (DED) is a prevalent condition that commonly affects patients of working age in addition to the elderly. DED is a complex condition that results in ocular symptoms such as dryness and burning and signs such as decreased tear production (aqueous deficient DED) or increased tear evaporation (evaporative DED). Unfortunately, there is not a perfect correlation between DED signs and symptoms, which makes diagnosis and timely treatment challenging.

High Resolution, High-speed Multimodal Ophthalmic Imaging

Knowledge of the pathogenesis of ocular conditions, a leading cause of blindness, has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems are limited in resolution, speed, or access to certain structures of the eye. The use of a high-resolution imaging system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many microstructures of the eye: photoreceptors, vessels, nerve bundles in the retina, cells and nerves in the cornea. The use of a high-speed acquisition imaging system makes it possible to detect functional measurements such as the speed of blood flow. The combination of data from multiple imaging systems to obtain multimodal information is of great importance for improving the understanding of structural changes in the eye during a disease. The purpose of this project is to observe structures that are not detectable with routinely used systems.

Evaluation of New Color Temperature Adjustment Mode in Preventing Dry Eye and Visual Fatigue

The Effect of Eyeliner on Tear Composition, Tear Secretion and Tear Film Stability.

Eyeliner is one of the most common eye cosmetics. The main ingredients are titanium oxide, pigment, grease and preservative. The user will apply the eyeliner to the eyelid and eyelash. With the blinking again and again, the components of the eyeliner may enter the tear film and continue to act on the eye surface. Therefore, the investigators suspect that the use of eyeliner may be an important factor leading to dry eye disease. In order to explore the relationship between the use of eyeliner and dry eye disease, the investigators plan to collect eye surface characteristic data of the two groups of people who use eyeliner and who do not use it.Then use Raman analysis to explore whether the use of eyeliner will lead to changes in tear composition.The investigators intend to analyze the difference of tear composition between the two groups to understand the relationship between the change of tear composition and tear film stability.So that the investigators can identify the risk factors of dry eye disease, and provide basis for prevention and early treatment.

Assessment of CataClear, Tear Film Stability, Tear Volume, and Dry Eye Symptoms Using Stem Cells Fortified Eye Drops

Dry Eye Disease (DED) is a multifactorial condition that affects the ocular surface, leading to discomfort, tear film instability, and potential visual disturbances. Its global prevalence ranges between 5% and 50%, making it a significant cause of reduced quality of life and a growing burden on healthcare systems. Cataract, defined as a progressive opacification of the lens, remains the leading cause of preventable blindness worldwide, responsible for about 33% of all cases, affecting an estimated 94 million people. Its incidence increases with age and is influenced by factors such as ultraviolet exposure, diabetes, smoking, and genetic predisposition. Low- and middle-income countries (LMICs) face a disproportionately high burden due to limited access to surgical care. The economic impact of cataract is profound, including both direct costs (surgery, post-op care) and indirect costs (lost productivity, caregiver dependency), with global productivity losses estimated at $53 billion annually. Beyond economics, cataract significantly impairs quality of life, contributing to psychological distress, depression, loss of independence, and increased risk of cognitive decline. Addressing this burden requires integrated strategies that ensure equitable access to treatment, reduce financial barriers, and include psychosocial support. In parallel, emerging regenerative therapies such as stem cell-fortified eye drops offer new hope. These treatments, utilizing mesenchymal stem cells (MSCs), aim to restore ocular surface health in conditions like DED by reducing inflammation and enhancing tissue repair. The current study evaluates the efficacy of such drops in improving tear film stability, tear volume, and overall clinical symptoms using advanced diagnostic tools.
