What is being measured

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

  1. Slit Lamp Findings - Corneal Edema

    Investigators examined subjects using a slit lamp and the following scale: 0=none, 1=trace, 2=mild, 3=moderate, 4=severe. This outcome measures the number of eyes that had corneal edema graded 2 or higher at the 1-week visit.

    Measured: after 1 week of lens wear

  2. Corneal Edema at Month 1

    Number of eyes with corneal edema graded 2 or higher at the 1 month visit. Investigators examined subjects using a slit lamp and the following scale: 0=none, 1=trace, 2=mild, 3=moderate, 4=severe.

    Measured: after 1 month of lens wear

  3. Slit Lamp Findings - Corneal Neovascularization

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had corneal neovascularization graded 2 or higher at the 1-week visit.

    Measured: after 1 week of lens wear

  4. Slit Lamp Findings - Corneal Neovascularization

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had corneal neovascularization graded 2 or higher at the 1-week visit.

    Measured: after 1 month of lens wear

  5. Slit Lamp Findings - Corneal Staining

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had corneal staining graded 2 or higher at the 1-week visit.

    Measured: after 1 week of lens wear

  6. Slit Lamp Findings - Corneal Staining

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had corneal staining graded 2 or higher at the 1-week visit.

    Measured: after 1 month of lens wear

  7. Slit Lamp Findings - Injection

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had injection graded 2 or higher at the 1-week visit.

    Measured: after 1 week of lens wear

  8. Slit Lamp Findings - Injection

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had injection graded 2 or higher at the 1-week visit.

    Measured: after 1 month of lens wear

  9. Slit Lamp Findings - Tarsal Abnormalities

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had tarsal abnormalities graded 2 or higher at the 1-week visit.

    Measured: after 1 week of lens wear

  10. Slit Lamp Findings - Tarsal Abnormalities

    Investigators examined subjects using a slit lamp and the following scale:0=none, 1=trace, 2=mild, 3=moderate, 4= severe. This outcome measures the number of eyes that had tarsal abnormalities graded 2 or higher at the 1-week visit.

    Measured: after 1 month of lens wear

  11. Slit Lamp Findings - Infiltrates

    Investigators examined subjects using a slit lamp and recorded the presence or absence of infiltrates. This outcome measures the number of eyes that had infiltrates present at the 1-week visit.

    Measured: after 1 week of lens wear

  12. Slit Lamp Findings - Infiltrates

    Investigators examined subjects using a slit lamp and recorded the presence or absence of infiltrates. This outcome measures the number of eyes that had infiltrates present at the 1-week visit.

    Measured: after 1 month of lens wear

  13. Subject Reported Symptoms

    Number of eyes in which subjects reported lens-related symptoms after 1 week of lens wear.

    Measured: after 1 week of lens wear

  14. Subject Reported Symptoms

    Number of eyes in which subjects reported lens-related symptoms after 1 month of lens wear.

    Measured: after 1 month of lens wear

  15. Visual Acuity (VA)

    Investigators assessed visual acuity per eye using a Snellen visual acuity chart. This outcome measures the number of eyes, wearing vision correction, that measured visual acuity worse than 20/30 at the 1-week visit.

    Measured: after 1 week

  16. Visual Acuity (VA)

    Investigators assessed visual acuity per eye using a Snellen visual acuity chart. This outcome measures the number of eyes, wearing vision correction, that measured visual acuity worse than 20/30 at the 1-month visit.

    Measured: after 1 month

  17. Average Wear Time

    Measured: after 1 week of lens wear

  18. Average Wear Time

    Measured: after 1 month of lens wear

Questions about this trial

What is this clinical trial studying?

A study testing narafilcon B and etafilcon A in people with Myopia, run by Johnson & Johnson Vision Care, Inc. at 3 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 3 inclusion and 6 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 3 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 17 Mar 2011). 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?

Slit Lamp Findings - Corneal Edema (time frame: after 1 week of lens wear). The study lists 18 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.
