About this study

Dry eye is a chronic irritating eye condition that affects many people, caused by poor tear quality and insufficient quantity. Treatments are traditionally in the form of artificial tears applied to the ocular surface. However, there is little evidence in the scientific literature that demonstrates their efficacy relative compared to each other, nor how to decide which one might be most effective for an individual patient. Therefore the investigators aim to examine the efficacy of different classes of artificial tears (those designed to increase viscosity, reduce evaporation or to mimic the component balance of the natural tears). In addition, the investigators also aim to determine how the treatment preferred by an individual could potentially have been predicted from their baseline condition.

Read the detailed description

The efficacy of different classes of artificial tears (non-pharmaceutical) will be examined in patients that report dry eyes by prescribing each category of treatment [0.40% Sodium Hyaluronate (Clinitas Soothe), 0.15% Sodium Hyaluronate (Hyabak), 0.25% Carboxymethylcellulose, electrolyte balanced (Theratears), and Phospholipid liposomal spray (Tears Again)] for a month in turn following a short wash-out period and to examine their tear film and ocular surface after each one.

What is being measured

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

  1. Symptoms

    Short questionnaire (Ocular Surface Disease Index)

    Measured: 4 months

Secondary outcomes (5)
  1. Non-invasive break-up time

    Tear stability will be assessed using the Purkinje reflection from the tear film on the ocular surface recording the time (in seconds) that the reflection is first distorted, observed with a slit lamp biomicroscope

    Measured: 4 months

  2. Tear meniscus height

    Tear meniscus height will be assessed in millimetres by comparing to the slit height adjustment of a slit lamp biomicroscope.

    Measured: 4 months

  3. lid parallel conjunctival folds

    Lid parallel conjunctival folds will counted as observed with a slit lamp biomicroscope and timed/graded

    Measured: 4 months

  4. Ocular Surface Staining

    Ocular surface staining with fluorescein and lissamine green dyes will be observed with a slitlamp biomicroscope and graded using the Efron grading scale

    Measured: 4 months

  5. Phenol Red Test

    Tear volume will be quantified in millimetres after 15s with the tip inserted in the lower tear meniscus from the wetting height of a phenol red impregnated strip inserted in the lower fornix for 15 seconds

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Hypromellose 0.15%, Hypromellose 0.4% and Carboxymethylcellulose in people with Dry Eye, run by Aston University at 1 site in United Kingdom.

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 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: finished, as of the sponsor's last update on 10 Jan 2019. 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 United Kingdom. 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.

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?

Symptoms (time frame: 4 months). 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 10 Jan 2019.
