NCT06517667

Brief Summary

The objective of the study is to compare the efficacy and safety of different hyaluronic acid tear substitutes formulations in patients with evaporative dry eye. For this purpose, a randomized, single-blind clinical trial has been designed.

Outcome Measures

Primary Outcomes (1)

  • Lipid layer thickness (LLT)

    The Lipiview® (Johnson \& JohsonVision Care, San Francisco, CA, USA) II ocular surface interferometer evaluates LLT automatically assesses LLT with nanometer precision by recording a 20 s video of the tear film interference pattern and then displays the data in interferometric color units (ICU), where1 ICU reflects approximately 1 nm of LLT.

    This outcome measure was analyzed at baseline, 1 months and 3 months.

Secondary Outcomes (3)

  • Ocular surface disease index questionnaire

    This outcome measure was analyzed at baseline, 1 months and 3 months.

  • Non-invasive tear film break-up time

    This outcome measure was analyzed at baseline, 1 months and 3 months.

  • Schirmer I test without anesthesia

    This outcome measure was analyzed at baseline, 1 months and 3 months.

Study Arms (2)

Cross-linked hyaluronic acid

EXPERIMENTAL

Tear substitute based on 0.20% Cross-linked hyaluronic acid

Drug: Icross tear substitute

Hyaluronic acid

ACTIVE COMPARATOR

Tear substitute based on 0.15% Cross-linked hyaluronic acid

Drug: Hyabak tear substitute

Interventions

Patients were instructed to instill 1 drop of 0.20% Cross-linked hyaluronic acid substitute into each eye 3 times per day for 3 months.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Self-reported history DED.
  • 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.
