What is being measured
The primary outcome is the main question the study is designed to answer.
ocular surface disease index (OSDI)
OSDI is one of the most frequently used questionnaires for evaluation of dry eye disease (DED). This includes 12 questions which measure the frequency of symptoms over the recent week, and the scores range from 0 to 100.
Measured: from baseline to 3 months after treatment
Tear break-up time (TBUT)(s)
BUT is the time from normal blinking to the first appearance of a break in the tear film.
Measured: from baseline to 3 months after treatment
Corneal fluorescein staining (CFS)
The degree of fluorescein staining of the cornea was evaluated using the National Eye Institute (NEI) scale of five corneal regions (central, superior, temporal, nasal, and inferior). The scores range from 0 to 15.
Measured: from baseline to 3 months after treatment
Schirmer I test (SIt) (mm/5 minutes)
The Schirmer I test is performed using sterile strips without anesthesia. The strips are placed in the lateral part of the inferior fornix of the eye for 5min and the extent of tear flow down was measured in millimeters.
Measured: from baseline to 3 months after treatment
Lissamine green staining
To grade the temporal zone, the subject looks nasally; to grade the nasal zone the subject looks temporally. The upper and lower conjunctiva can also be graded.
Measured: from baseline to 3 months after treatment
Secondary outcomes (5)
corneal sensitivity (range, 60-0 mm)
Corneal sensitivity will be measured in the right eye only using the Cochet-Bonnet aesthesiometer and the ascending method of limits to determine the threshold of stimulus detection.
Measured: from baseline to 3 months after treatment
the concentration of Interleukin-1β (IL-1β) (pg/ml)
basal tears will be collected from the inferior meniscus of each subject to test this inflammatory cytokine. IL-1β levels will be quantified by Luminex immunoassay.
Measured: from baseline to 3 months after treatment
the concentration of Interleukin-6 (IL-6) (pg/ml)
basal tears will be collected from the inferior meniscus of each subject to test this inflammatory cytokine. IL-6 levels will be quantified by Luminex immunoassay.
Measured: from baseline to 3 months after treatment
the concentration of Interleukin-10 (IL-10) (pg/ml)
basal tears will be collected from the inferior meniscus of each subject to test this inflammatory cytokine. IL-10 levels will be quantified by Luminex immunoassay.
Measured: from baseline to 3 months after treatment
the concentration of Interleukin-17A (IL-17A) (pg/ml)
basal tears will be collected from the inferior meniscus of each subject to test this inflammatory cytokine. IL-17A levels will be quantified by Luminex immunoassay.
Measured: from baseline to 3 months after treatment

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing artificial tear eyedrops and 0.05% cyclosporine eyedrops in people with Dry Eye, run by Peking University Third Hospital at 1 site in China.
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 3 inclusion and 3 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 13 Feb 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 China. 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?
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 to 3 months after treatment). The study lists 5 primary outcomes in all. 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 13 Feb 2025.
