What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation Between Subjective CLUE Comfort and Keratometry

    CLUE- The Contact Lens User Evaluation (CLUE)™ 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. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20) with a range of 0-120, where higher scores indicate a more favorable/positive response (Wirth, RJ. Et al. August 2016). Keratometry measurements of major keratometric meridians (diopter [DK]) and their location (degrees) was collected at baseline for both eyes. The correlation between CLUE comfort and maximum Keratometry measurements of the two eyes within each subject and the correlation between CLUE comfort and the minimum Keratometry measurements of the two eyes within each subject were reported.

    Measured: 3-day follow-up

  2. Correlation Between Subjective CLUE Comfort and Corneal Diameter

    Assessment The Contact Lens User Evaluation (CLUE)™ 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. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20) with a range of 0-120, where higher scores indicate a more favorable/positive response (Wirth, RJ Et al. August 2016). Corneal diameter (horizontal visible iris diameter [HVID]) was collected at baseline for both eyes using a slit lamp reticle, measuring to the nearest 0.05 mm.The maximum (or minimum) measurements of HVID between the two eyes of each subject were used for correlation analyses between subjective CLUE comfort score and corneal diameter.

    Measured: 3-day follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Contact Lenses with 8.5 BC and Contact Lenses with 9.0 BC in people with Contact Lens Base Curve (BC) Fit and Comfort, run by Johnson & Johnson Vision Care, Inc. at 2 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 10 inclusion and 12 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 11 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Jan 2017). 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?

Correlation Between Subjective CLUE Comfort and Keratometry (time frame: 3-day follow-up). The study lists 2 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 11 Jul 2017.
