About this study

Official title: Effect of Contact Lens Wear on Immune Cell Density and Morphology of the Ocular Surface: A Laser In Vivo Confocal Microscopy Study

The purpose of this study is to utilize in-vivo confocal microscopy to describe differences in corneal epithelial immune status across three lens care regimens in new contact lens wearers.

Read the detailed description

An estimated 40 million people in the United States wear contact lenses, with approximately 38 million soft lens wearers and 2 million rigid gas permeable lens wearers. The ocular surface has been shown to respond to the introduction of foreign materials with upregulation of proinflammatory mediators, leading to an increase in inflammation. The corneal can show a foreign body immune response to contact lenses. The purpose of this study is to utilize in-vivo confocal microscopy to describe differences in corneal epithelial immune status across the three lens care regimens in new contact lens wearers.

What is being measured

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

  1. Corneal Epithelial Immune Dendritic Cell Density (Central Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  2. Corneal Epithelial Immune Dendritic Cell Density (Inferior Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  3. Corneal Epithelial Immune Dendritic Cell Density (Nasal Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  4. Corneal Epithelial Immune Dendritic Cell Density (Superior Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  5. Corneal Epithelial Immune Dendritic Cell Density (Temporal Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  6. Corneal Epithelial Immune Non-Dendritic Cell Density (Central Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  7. Corneal Epithelial Immune Non-Dendritic Cell Density (Inferior Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  8. Corneal Epithelial Immune Non-Dendritic Cell Density (Nasal Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  9. Corneal Epithelial Immune Non-Dendritic Cell Density (Superior Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

  10. Corneal Epithelial Immune Non-Dendritic Cell Density (Temporal Cornea)

    The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

    Measured: Six weeks

Secondary outcomes (1)
  1. Number of Participants With Slit-lamp Findings, Corrected Visual Acuity (Snellen) and Adverse Events

    The safety analysis will be based on slit-lamp findings, corrected visual acuity (Snellen) and adverse events (if any). No inferential statistical analyses are planned for any safety variable.

    Measured: Six weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ReNu MultiPlus® MultiPurpose Solution, OPTI-FREE® RepleniSH® and Clear Care® in people with Myopia and Refractive Error, run by Massachusetts Eye and Ear Infirmary at 2 sites in United States.

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 10 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Yes. Results are posted in the registry (first posted 10 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Corneal Epithelial Immune Dendritic Cell Density (Central Cornea) (time frame: Six weeks). The study lists 10 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 10 Jan 2017.
