Pilot Clinical Evaluation of Approved Contact Lenses

June 16, 2017 updated by: Johnson & Johnson Vision Care, Inc.

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study
