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

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects will wear two different contact lens study products in a cross-over fashion. Each study product type will be worn for approximately 14 days. A washout period of 2-4 days will occur prior to the first wear period and between the two wear periods. Subjects will be expected to attend 7 office visits. The total duration of study participation is approximately 40 days with approximately 28 days of lens wear.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Binocular Visual Acuity at Distance (4 Meters) at Week 1
Time Frame: Week 1 (Day 7 -0/+1 days) of each wear period. A wear period was 14 days (-0/+2 days) according to randomization assignment.
Visual Acuity (VA) was assessed at a distance of 4 meters with both eyes together (binocular) under high contrast, high illumination lighting with study lenses in place. VA was measured using letter charts and recorded in the logarithm of the minimum angle of resolution (LogMAR). A LogMAR value of 0 equates to 20/20 Snellen VA (normal distance eyesight), with negative LogMAR values representing better than 20/20 VA. The LogMAR VA scale ranges from -0.30 (20/10 Snellen) to 1.00 (20/200 Snellen). No hypothesis testing was pre-specified for this endpoint.
Week 1 (Day 7 -0/+1 days) of each wear period. A wear period was 14 days (-0/+2 days) according to randomization assignment.
