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

151

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

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Willing to sign an Informed Consent Document or Assent, if applicable.
  • Vision correctable to 20/30 Snellen (feet) or better in each eye at distance with pre-study contact lenses.
  • Manifest cylinder (at screening) less than or equal to 0.75 diopters (D) in each eye.
  • Successful wear of clear/handling tint, single-vision spherical, bi-weekly/ monthly replacement soft contact lenses in both eyes during the past 2 months for a minimum of 5 days per week and 8 hours per day.
  • Requires spherical contact lenses within the available range of powers (i.e.,-1.50D to -5.00D in 0.25D steps).
  • Interested in wearing contact lenses that change the appearance of the color of the eyes.
  • Other protocol-specified inclusion criteria may apply.

Exclusion Criteria:

  • Any anterior segment infection, inflammation, disease or abnormality that contraindicates contact lens wear (within 7 days of enrollment, or current).
  • History of herpetic keratitis.
  • Any use of systemic or ocular medications for which contact lens wear could be contraindicated including any use of topical ocular medications that would require instillation during contact lens wear, except for rewetting drops.
  • Corneal vascularization greater than 1 millimeter (mm) of penetration.
  • Habitual lenses worn in an extended wear modality (routinely sleeping in lenses overnight for 1 night per week or more) over the last 3 months prior to enrollment.
  • Previous corneal or refractive surgery or irregular cornea.
  • Monovision and monocular (only 1 eye with functional vision) or fit with only 1 lens.
  • Anisometropia ≥1.50D (study contact lens prescription).
  • History of intolerance or hypersensitivity to any component of the test articles.
  • Eye injury or ocular or intra-ocular surgery within the last 6 months (excluding placement of punctal plugs).
  • Participation in any clinical study within 30 days of Visit 1.
  • Other protocol-specified exclusion criteria may apply.

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
Lens Comfort Likert Response at Day 30
Time Frame: Day 30
Subject indicated agreement with the following statement, "These lenses provided the same excellent comfort at the end of the month as they did at the beginning of the month" using a 4-point Likert scale, where 1=Strongly disagree, 2=Disagree; 3=Agree; 4=Strongly agree. The Top 2 responses (agree, strongly agree) were calculated and reported as a percentage of all responses. Both eyes were rated together. This outcome measure was prespecified for the AIR OPTIX COLORS arm only.
Day 30

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Lens Comfort Likert Response at Day 14
Time Frame: Day 14
Subject indicated agreement with the following statement, "These lenses provided the same excellent comfort at the end of two weeks as they did at the beginning of the two weeks" using a 4-point Likert scale, where 1=Strongly disagree, 2=Disagree; 3=Agree; 4=Strongly agree. The Top 2 responses (agree, strongly agree) were calculated and reported as a percentage of all responses. Both eyes were rated together. This outcome measure is prespecified for the AIR OPTIX COLORS arm only.
Day 14
Lens Comfort 1-10 Scale Response
Time Frame: Day 30
Subject was instructed, "Please rate your comfort with the study lenses," using a scale from 1-10, where 1=poor and 10=excellent. Both eyes were rated together.
Day 30

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
