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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

79

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

41 years to 68 years (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
End of Day Comfort
Time Frame: 5 days of wear, lenses replaced daily
End of day comfort was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. End of day comfort was measured on a 10-point scale, with 1 being poor and 10 being excellent.
5 days of wear, lenses replaced daily
End of Day Dryness
Time Frame: 5 days of wear, lenses replaced daily
End of day dryness was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. End of day dryness was measured on a 10-point scale, with 1 being very dry and 10 being not dry.
5 days of wear, lenses replaced daily
Handling at Removal
Time Frame: 5 days of wear, lenses replaced daily
Handling at removal was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. Handling at removal was measured on a 10-point scale, with 1 being poor/difficult and 10 being excellent/easy.
5 days of wear, lenses replaced daily
Overall Vision
Time Frame: 5 days of wear, lenses replaced daily
Overall vision was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. Overall vision was measured on a 10-point scale, with 1 being poor and 10 being excellent.
5 days of wear, lenses replaced daily

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
Overall Fit
Time Frame: Day 5, lenses replaced daily
Overall lens fit was assessed by the investigator at study visit using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye. Lens fit was assessed by eye and graded on a 5-point scale, with 2=unacceptably loose, 1= acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight
Day 5, lenses replaced daily

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2010

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.
January 1, 2011

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
