About this study

Official title: Multicomponent Dietary Supplementation: Impact on Tear Secretion and Ocular Surface Inflammation in Dry Eye Syndrome Patients

The goal of this clinical trial is to explore the effect of supplementation of fish oil, lutein and zeaxanthin on the symptoms of dry eye syndrome, antioxidant capacity, oxidative stress and anti-inflammatory capacity in DES patients., it aims to answer are:

To evaluate the effects of a 12-week multicomponent dietary supplementation (capsule content are eicosapentaenoic acid 45 mg, docosahexaenoic acid 30 mg, lutein 30 mg, and zeaxanthin1.8 mg)on symptoms of dry eye syndrome, oxidative stress, antioxidant capacity, and inflammation.

To investigate the relationships between dry eye symptoms, oxidative stress, antioxidant capacity, and inflammation.

Participants will be randomly assigned to control group (n = 50) and supplement group (n = 50) and white pomegranate extract group (n = 50) for 12 weeks. Participants will complete assessments of tear secretion, antioxidant capacity, and ocular surface inflammation.

Read the detailed description
  1. Study Participants i. Inclusion criteria: (1) Aged 20 to 80 years; (2) Diagnosed with moderate or greater dry eye syndrome by an ophthalmologist. ii. Exclusion criteria: Previous ocular surgery within the last 3 months. iii. Withdrawal Criteria Participants are free to decide whether to participate in this trial, and they can withdraw their consent at any time during the trial without providing any reason. If participants experience discomfort, they may withdraw from the trial at any time without facing any penalties or compromising their rights. iv. Participants were randomly assigned to a supplement group or control group. Participants in supplement group were asked to take a capsule content are eicosapentaenoic acid 45 mg, docosahexaenoic acid 30 mg, lutein 30 mg, and zeaxanthin1.8 mg every day for 12 weeks.
  2. Subject Recruitment Interested participants will be recruited openly through posters posted at Chung Shan Medical University Hospital. The researchers will explain the trial content for 15-20 minutes, and if interested, participants will sign the informed consent form.
  3. Research Methods At weeks 0 and 12 of the trial, 10 μL of tear samples and 10 mL of blood samples will be collected from participants.
  4. The basic and OSDI questionnaires and ii. Evaluate dry eye-related indicators evaluation iii. Measure blood or tear oxidative stress and antioxidant capacity, and tear inflammatory factors were measured.
  5. All statistical data will be analyzed using SigmaPlot statistical software (version 12.5; Systat Software, San Jose, CA), and the data will be presented using an intention-to-treat (ITT) approach. The differences in continuous data between the two groups will be compared using the Student's t-test. The differences in values within the group before and after intervention will be compared using the paired t-test. The differences in ordinal data between the two groups will be assessed using the Chi-square test. Partial Spearman's correlation will be used to adjust for confounding factors (age, gender, and menopause status) to explore the correlations between changes in oxidative stress and antioxidant capacity in blood and tears, changes in inflammatory factors, and changes in dry eye assessment. Multiple linear regression will be used to analyze the effect of supplement intake on changes in oxidative stress and antioxidant capacity in blood and tears, changes in inflammatory factors, and changes in dry eye assessment. The data will be expressed as mean ± standard deviation (SD), with p < 0.05 indicating statistical significance.

Through this study, the administration of multicomponent dietary supplementation to patients with dry eye syndrome aims to understand whether different eye health nutrients improve tear secretion, antioxidant capacity, and anti-inflammatory responses. This may serve as an adjunctive treatment or symptom relief for dry eye syndrome.

Questions about this trial

What is this clinical trial studying?

A study testing Multicomponent dietary supplement group in people with Dry Eye Syndrome (DES), run by Shih Chien Huang at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ocular Surface Disease Index (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2025.
