Brief Summary

The objective of the study is to assess the efficacy and safety of TriMix tear substitute in patients with dry eye disease. For this purpose, a randomized, double-blind clinical trial has been designed, using an Hyaluronic acid-based tear substitute as a control.

Conditions

Dry Eye

Outcome Measures

Primary Outcomes (3)

• Ocular surface disease index questionnaire

  The OSDI questionnaire were employed to assess the severity of DED symptoms, with scores ranging from 0 (indicating no ocular surface disease) to 100 (indicating severe ocular surface disease) points. This questionnaire was provided during consultations at each follow-up visit.

  This outcome measure was analyzed at baseline, 3 months and 6 months.

• Non-invasive tear film break-up time

  Tear film stability was automatically assessed using NIBUT by projecting Placido rings from the Sirius device (CSO, Florence, Italy) onto the corneal surface. The time interval between the last blink and the initial distortion of the ring pattern was defined as first NIBUT. This variable was always measured at least 12 hours after administration of the study medication and the average of 3 consecutive measurements was calculated for statistical analysis.

  This outcome measure was analyzed at baseline, 3 months and 6 months.

• Schirmer I test without anesthesia

  During the test, the patient is instructed to look upward while the test strip is carefully positioned between the palpebral conjunctiva of the lower eyelid and the bulbar conjunctiva. Subsequently, the patient is asked to keep their eyes gently closed for five minutes. After this period, the test strip is removed, and the Schirmer test score is determined by measuring the length of the moistened area on the strip.

  This outcome measure was analyzed at baseline, 3 months and 6 months.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Self-reported history DED while working with computer screens ≥ 6 hours per day.
• ocular surface disease index (OSDI) \> 13 points.
• non-invasive tear film break-up time (NIBUT) \< 10 s.
• Schirmer test (ST) without anesthesia ≥ 5 mm.
• MGD grade ≤ 1. For MGD, the Sirius device (CSO, Florence, Italy) was used, which determines MGD grade based on loss area of meibomian glands (LAMG). MGD grade was scored from 0 to 4 (MGD grade 1 = LAMG \< 25%; MGD grade 2 = LAMG ≥ 25% and \< 50%; MGD grade 3 = LAMG ≥ 50% and \< 75%; MGD grade 4 = LAMG ≥ 75%).

You may not qualify if:

• abnormal lid anatomy, including active blepharitis, and active lid margin.
• all corneal disorders that affect diagnostic test, such as active corneal infection and corneal dystrophies.
• active ocular allergies.
• vectored thermal pulsation (VTP) intense pulse light (IPL), quantum molecular resonance (QMR), or other procedure to treat DED within the previous 6 months.
• intraocular surgery or laser ocular surgery within the previous 6 months.
• use of topical antibiotics and anti-inflammatory treatments, including steroids and non-steroidal anti-inflammatory drugs.
• systemic autoimmune diseases.
• contact lens wearers.
• pregnant or lactating women.
• patients who did not understand or comprehend the informed consent.

• Study Type: interventional
• Phase: phase 2
• Allocation: RANDOMIZED
• Masking: QUADRUPLE
• Who Masked: PARTICIPANT, CARE PROVIDER, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: TriMix tear substitute and 0.15% HA tear substitute are transparent, with no special smell and the bottles were identical in appearance such that patients, investigators and care provider were masked to treatment assignment.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: OD, PhD

Model Details: Patients were instructed to instill 1 drop TriMix tear substitute or 0.15% HA tear substitute into each eye 3 times per day for 6 months. HA-based tear substitutes can reduce tear film hyperosmolarity and are effective in treating DED. Therefore, 0.15% HA tear substitute was selected as a suitable comparator.
