About this study
Official title: Efficacy of 0.28% Sodium Hyaluronate Eye Drops in Patient With Moderate to Severe Dry Eye : A Randomized Double-blind Controlled Trial
This study aimed to evaluate the efficacy and safety of 0.28% preservative-free SH and 0.18% SH eye drops in patients with dry eye disease. Subjects diagnosed with dry eye disease and meeting the inclusion criteria (Ocular Surface Disease Index (OSDI) score ≥ 23, Fluorescein Tear Breakup Time (TBUT) < 7 seconds were randomized into two groups. Group 1 (42 eyes) received 0.28% SH, and Group 2 (42 eyes) received 0.18% SH, both administered by a nurse. Measurements included tear osmolarity (TearLAB) before instillation and at 0,30 and 60 minutes post-instillation, recorded by a TearLAB specialist. Ophthalmologists assessed TBUT, ocular surface staining (Oxford grading scale), and the Schirmer I test before instillation and evaluated adverse reactions up to 60 minutes post-instillation. Subjects continued treatment for 30 days and were reevaluated during a second visit for OSDI scores, TBUT, the Oxford grading scale, and adverse events. Quality of life score were assessed at before and after treatment for 1 month.

What is being measured
The primary outcome is the main question the study is designed to answer.
To examine the effect of 0.28% Sodium Hyaluronate on corneal epithelial healing
The Oxford grading scale was used. This scale consists of six levels: 0, I, II, III, IV, and V, with higher values indicating more severe punctate epithelial erosion.
Measured: 30 days
To examine the effect of 0.28% Sodium Hyaluronate on reducing tear osmolarity
Tear osmolarity was monitored before and after the intervention in both arms. Abnormal Tear Osmolarity is defined as a value of ≥ 308 mOsmol/L, measured using the TearLab® system.
Measured: 60 minutes
Secondary outcomes (3)
3. To study the stability of the tear film following the administration of 0.28% Sodium Hyaluronate
Fluorescein Tear Break-Up Time (FTBUT) was measured in seconds. Abnormal values are defined as a tear break-up time of ≥ 10 seconds.
Measured: 0 minutes, 60 minutes, and 30 days.
To assess dry eye symptoms following the administration of 0.28% Sodium Hyaluronate
The Ocular Surface Disease Index (OSDI) was used. The final score is calculated on a scale from 0 to 100, with higher scores indicating greater severity of ocular surface dysfunction.
Measured: 0 minutes and 30 days.
To assess quality of life following the administration of 0.28% Sodium Hyaluronate
The Dry Eye-Related Quality of Life Score (DEQS-Th) was used. The final score is calculated on a scale from 0 to 100, with higher scores indicating greater severity of ocular surface dysfunction.
Measured: 0 minutes and 30 days.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study aimed to evaluate the efficacy and safety of 0.28% preservative-free SH and 0.18% SH eye drops in patients with dry eye disease. Subjects diagnosed with dry eye disease and meeting the inclusion criteria (Ocular Surface Disease Index (OSDI) score ≥ 23, Fluorescein Tear Breakup Time (TBUT) < 7 seconds were randomized into two groups. Group 1 (42 eyes) received 0.28% SH, and Group 2 (42 eyes) received 0.18% SH, both administered by a nurse. Measurements included tear osmolarity (TearLAB) before instillation and at 0,30 and 60 minutes post-instillation, recorded by a TearLAB specialist. Ophthalmologists assessed TBUT, ocular surface staining (Oxford grading scale), and the Schirmer I test before instillation and evaluated adverse reactions up to 60 minutes post-instillation. Subjects continued treatment for 30 days and were reevaluated during a second visit for OSDI scores, TBUT, the Oxford grading scale, and adverse events. Quality of life score were assessed at before and after treatment for 1 month.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing 0.28% Sodium Hyaluronate , preservative free eye drops and 0.18% Sodium Hyaluronate , preservative free eye drops in people with Dry Eye Disease (DED) and Tear Break-Up Time, run by Department of Medical Services Ministry of Public Health of Thailand at 1 site in Thailand.
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 5 inclusion and 8 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: enrolling by invitation, 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 Thailand. 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?
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?
This study is still under way. Results are not available in the source record yet.
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?
To examine the effect of 0.28% Sodium Hyaluronate on corneal epithelial healing (time frame: 30 days). The study lists 2 primary outcomes in all. 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 NCT06860659, which also lists 23 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 6 Mar 2025.
