What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Three 15-minute sessions were performed at weekly intervals. The treatment was delivered with a wavelength of 625 nm and a radiance of 35 mW/cm², resulting in a total energy dose of approximately 32 J/cm² applied to the facial and eyelid regions with eyes closed.

  • Topical Cyclosporine ADrug

    CsA 0.1% twice per day

  • Topical tacrolimusDrug

    Tacrolimus 0.1% twice per day

What is being measured

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

  1. Ocular surface disease index (OSDI)

    A standardized questionnaire designed to assess the symptoms of dry eye disease and their impact on vision-related functioning. It consists of 12 items that evaluate the frequency of symptoms, environmental triggers, and functional limitations over the previous week. The OSDI provides a score from 0 to 100, with higher scores indicating more severe symptoms.

    Measured: From baseline visit to the end of follow-up (12 months)

Secondary outcomes (2)
  1. Non-invasive tear film break-up time (NIBUT)

    NIBUT is a clinical test used to evaluate tear film stability without the use of dyes. It measures the time interval between a complete blink and the first appearance of a disruption or break in the tear film. Shorter NIBUT values indicate reduced tear film stability.

    Measured: From baseline visit to the end of follow-up (12 months)

  2. Tear meniscus height (TMH)

    TMH is a quantitative parameter used to assess tear volume. Reduced TMH values are indicative of aqueous tear deficiency.

    Measured: From baseline visit to the end of follow-up (12 months)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Low-level light therapy (LLLT), Topical Cyclosporine A and Topical tacrolimus in people with Dry Eye Disease (DED), run by University of Seville at 2 sites in Italy.

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 1 inclusion and 1 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 20 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Italy. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

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 (OSDI) (time frame: From baseline visit to the end of follow-up (12 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07239128, which also lists 3 linked publications.

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 20 Nov 2025.
