What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Acuity Monocular
Snellen monocular visual acuity measurement was measured in both eyes that wore lenses for one week and came in for the evaluation with an inserted lens.
Measured: after 7 +/- 1 days of lens wear
Visual Acuity Binocular
Snellen binocular visual acuity measurement
Measured: after 7 +/- 1 days of lens wear
Subjective Assessment of Lens Comfort Using the Contact Lens User Experience (CLUE)TM Questionnaire.
The contract Lens Experience (CLUE)TM questionnaire is a validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
Measured: after 7 +/-1 days of lens wear
Subjective Assessment of Quality of Vision Using the Contact Lens User Experience(CLUE)TM Questionnaire.
Contact Lens User Experience CLUE)TM questionnaire: A validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
Measured: after 7 +/- 1 days of lens wear
Secondary outcomes (3)
Limbal Redness
Scale of 0 to 4, where 0=None, 2=Trace, 3=Mild, 4=Moderate, 5=Severe.
Measured: after 7 days of lens wear
Bulbar Redness
Scale of 0 to 4, where 0=None, 2=Trace, 3=Mild, 4=Moderate, 5=Severe.
Measured: after 7 days of lens wear

Questions about this trial
What is this clinical trial studying?
A study testing galyfilcon A prototype lens and comfilcon A in people with Myopia, run by Johnson & Johnson Vision Care, Inc. at 4 sites 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 6 inclusion and 10 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 19 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites 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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Visual Acuity Monocular (time frame: after 7 +/- 1 days of lens wear). The study lists 4 primary outcomes in all. 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 19 Jun 2018.
