Dry Eye Syndrome (DES)

Compare eye dryness following laser-assisted in situ keratomileusis (LASIK) surgery to eye dryness prior to receiving perioperative Miebo in patients with dry eye disease (DED)

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.

The objective of this 2-part study is to assess the safety and tolerability of the new ocular lubricating drop ABR2 during short-term use in subjects for the temporary relief of ocular discomfort due to dryness of the eye. In Part 1, participant will receive 1 drop of ABR2 in one eye and through assessments over a 1-hour period. In Part 2, participant will use 1 drop of ABR2 at least two times a day for 28-day period (may use up to 4 times a day as needed) This is a single arm, open label study with no placebo or comparative arm.

This is a single-center prospective open-label, clinical trial to explore proteomic expression of tear fluid biomarkers in patients with dry eye treated with Lifitegrast.

The goal of this clinical trial is to learn whether Kelulut honey eyedrops are safe and helpful in treating dry eye disease in adults. It will also learn about any side effects that may occur with the use of Kelulut honey eyedrops. This Kelulut honey eyedrops are sterile ophthalmic solutions formulated with honey derived from stingless bees (Trigona spp.) at concentrations of 12.5% 25% and 50%. The eyedrop formulations are prepared according to a standardized laboratory protocol to ensure sterility, stability, and suitability for ocular use. Full formulation details are proprietary but can be provided to the ethics committee or regulatory authorities upon request. The main questions this clinical trial aims to answer are: 1. Does Kelulut honey improve tear film stability and dry eye symptoms? 2. Are Kelulut honey eyedrops safe and well tolerated on the ocular surface? Researchers will compare different concentrations of Kelulut honey eyedrops to determine which concentration provides the best balance of safety and clinical benefit. Participants will: 1. Use Kelulut honey eyedrops (12.5%, 25%, or 50%) three times daily for 1 month, in addition to continuing their usual dry eye treatments. 2. Attend scheduled follow-up visits (on week 2 and week 4) for eye examinations and dry eye assessments (e.g., TBUT, ocular surface staining, Schirmer test, and OSDI). 3. Report any changes in symptoms or any discomfort, including stinging, redness, irritation, or other adverse effects experienced during the study.

This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy of adding laser acupuncture at Fengchi (GB20), Zanzhu (BL2), Hegu (LI4), and Quchi (LI11) acupoints to standard care for the treatment of dry eye symptoms in both Sjögren's Syndrome-related dry eye (SJS-DES) and non-Sjögren's Syndrome-related dry eye (Non-SJS-DES) populations. A total of 140 dry eye patients will be recruited and divided into two groups: 70 participants with SJS-DES and 70 with Non-SJS-DES. Participants will be randomly assigned into three groups: Sham+LA group (60 participants receiving 4 weeks of placebo laser acupuncture followed by 4 weeks of active laser acupuncture), LA+LA group (60 participants receiving 4 weeks of active laser acupuncture followed by another 4 weeks of active laser acupuncture), and a Waiting List group (20 participants receiving no laser acupuncture treatment). Each session will target the Fengchi (GB20), Zanzhu (BL2), Hegu (LI4), and Quchi (LI11) acupoints bilaterally, performed twice a week. The total study period is 8 weeks, and the treatment efficacy will be assessed at the end of the 8-week treatment. The Waiting List group (20 participants) will not receive any laser acupuncture treatment during this period. Efficacy will be evaluated using the Numerical Rating Scale (NRS), Schirmer's test, Ocular Surface Disease Index (OSDI), EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI), Traditional Chinese Medicine (TCM) tongue diagnosis, TCM pulse diagnosis, TCM constitution questionnaire, TCM heart rate variability analysis, nailfold microcirculation assessment, and iris examination. This study aims to investigate the impact of laser acupuncture on dry eye symptom improvement and the potential markers that differentiate between SJS-DES and Non-SJS-DES patients. The goal is to develop a comprehensive integrated care model for early screening, diagnosis, and personalized treatment plans for Dry Eye Syndrome and Sjögren's Syndrome, achieving the ultimate objective of "Holistic Health Care."

By analyzing the differential proteins in exosomes, this study aims to understand the pathological mechanisms of SJS and DES, identify potential diagnostic and therapeutic methods, and advance the diagnosis and treatment of these diseases.
