About this study

Official title: Imaging of Conjunctival Microvasculature During Contact Lens Wear

This is a pilot evaluation to assess the feasibility of using novel imaging process to characterize lens edge and limbal epithelial thickness profile; lens movement with gaze and blink; and conjunctival microvasculature including fractal analysis of microvascular perfusion maps and blood flow velocity.

Read the detailed description

This is a pilot evaluation to assess the feasibility of using ultra-high resolution optical coherence tomography (OCT) to image and characterize lens edge and limbal epithelial thickness profile; lens movement with gaze and blink; and conjunctival microvasculature including fractal analysis of microvascular perfusion maps and blood flow velocity.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Marketed Contact Lens 1Device

    Also called etafilcon A

    Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

  • Marketed Contact Lens 2Device

    Also called nelfilcon A

    Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

  • Marketed Contact Lens 3Device

    Also called narafilcon A in 8.5 base curve

    Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

  • Marketed Contact Lens 4Device

    Also called narafilcon A in 9.0 base curve

    Marketed contact lens being worn by the subject in a bilateral fashion for approximately 6 hours (+/- 30 minutes).

Study groupRoleWhat they receive
Subject A (Neophytes)Active comparatorSubjects will wear the Marketed Contact Lens 1, Marketed Contact Lens 2, Marketed Contact Lens 3, and Marketed Contact Lens 4 for a 6-hour period in a bilateral and random fashion, with a washout period of one week between lenses. Each subject will randomly be assigned to one of four unique sequences of a 4 x 4 crossover design. A block size of two sequences will be used.
Receives: Device: Marketed Contact Lens 1; Device: Marketed Contact Lens 2; Device: Marketed Contact Lens 3; Device: Marketed Contact Lens 4
Subject B (Habitual Lens Wearers)Active comparatorSubjects will wear the Marketed Contact Lens 1, Marketed Contact Lens 2, Marketed Contact Lens 3, and Marketed Contact Lens 4 for a 6-hour period in a bilateral and random fashion, with a washout period of one week between lenses. Each subject will randomly be assigned to one of four unique sequences of a 4 x 4 crossover design. A block size of two sequences will be used.

What is being measured

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

  1. Assessment of Bulbar Conjunctival Blood Flow Velocity

    Bulbar conjunctival microvascular responses among different types of contact lenses after a period of lens wear will be observed and evaluated for clinical relevance findings.

    Measured: 4 contact lenses will be tested over a period of 21 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Marketed Contact Lens 1, Marketed Contact Lens 2 and Marketed Contact Lens 3 in people with Vision Disorders, run by Johnson & Johnson Vision Care, Inc. at 1 site 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 8 inclusion and 16 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 20 Jun 2017. 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 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Assessment of Bulbar Conjunctival Blood Flow Velocity (time frame: 4 contact lenses will be tested over a period of 21 days.). 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 20 Jun 2017.
