About this study

HydroEye® is a dietary omega 3 fatty acid supplement that contains both EPA and DHA, as well as GLA and ALA in the form of black currant seed oil. It also has vitamins A, E, C, B6, and magnesium, many of which are involved in fatty acid metabolism. In 2013, Sheppard et al. tested HydroEye® in dry eye patients who were not contact lens wearers and found that symptoms and corneal smoothness improved in response to HydroEye® supplementation. To date, HydroEye® has not been assessed in patients with contact lens discomfort; therefore, the purpose of this clinical trial is to determine the efficacy of HydroEye® as a treatment for contact lens discomfort.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Average Contact Lens Dry Eye Questionnaire (CLDEQ-8) Score

    The CLDEQ-8 is a contact lens specific symptoms survey, range = 0-37 with 37 being most symptomatic.

    Measured: 6 months

Secondary outcomes (7)
  1. Average of Tear LTB4 Levels in Picograms Per Milliliter

    If there is an adequate number of tear samples collected, LTB4 values will be tested with a biochemical assay to estimate eye surface inflammation. Pooled tears may be needed.

    Measured: Baseline, 6 months

  2. Average Standardized Patient Evaluation of Eye Dryness (SPEED) Questionnaire Score

    The SPEED is a dry eye specific symptoms survey, we are using the Rasch validated version; range = 0-28 with 28 being most symptomatic.

    Measured: 6 months

  3. Number of Participants With a Non-zero Neuropathic Pain Symptom Inventory (NPSI) Questionnaire Score

    NPSI is a pain specific symptoms survey; range = 0-100 with 100 being most symptomatic. The survey is used to assess serious and chronic pain; therefore the number of subjects with non-zero NPSI values was expected to be minimal, and change to non-zero values was measured in treatment and placebo arms.

    Measured: 6 months

  4. Average Tear Breakup Time in Seconds

    This is a measure of tear stability with higher values being better (seconds).

    Measured: 6 months

  5. Average Schirmer I Test in mm

    This is a measure of tear volume with higher values being better (0 mm - 35 mm).

    Measured: 6 months

  6. Average Corneal Staining Score

    This is a measure of eye irritation with higher values being worse (NEI scale with range of 0 to 15) with higher scores being worse.

    Measured: 6 months

  7. Average Conjunctival Staining Score

    This is a measure of eye irritation with higher values being worse (NEI scale with range of 0 to 18).

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing HydroEye® in people with Dry Eye and Contact Lens Complication, run by University of Alabama at Birmingham at 1 site in United States.

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 11 inclusion and 13 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: stopped early, as of the sponsor's last update on 6 Mar 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 United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Average Contact Lens Dry Eye Questionnaire (CLDEQ-8) Score (time frame: 6 months). 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 6 Mar 2025.
