What is being measured

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

  1. Corrected Distance Monocular Visual Measurement Reported as Visual Acuity (VA)

    As tested for each eye individually while wearing study lenses. VA was measured using a Snellen chart, which was converted into logMAR units (logarithm of the minimum angle of resolution). A 20/20 Snellen acuity equated to a logMAR acuity of 0.0 and was considered normal distance eyesight. Positive logMAR values indicated poorer vision, and negative values denoted better visual acuity.

    Measured: 1 week of wear, replacing lenses daily

  2. Overall Comfort

    As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 1 week of wear time. Overall comfort was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.

    Measured: 1 week of wear, replacing lenses daily

  3. Overall Vision Quality

    As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 1 week of wear time. Overall vision quality was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.

    Measured: 1 week of wear, replacing lenses daily

  4. Overall Handling

    As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 1 week of wear time. Overall handling was evaluated binocularly and rated on a 10-point scale, with 1 being difficult and 10 being easy.

    Measured: 1 week of wear, replacing lenses daily

Secondary outcomes (1)
  1. Overall Lens Fit

    As assessed for each eye individually by the investigator using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye. Lens fit is reported on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight.

    Measured: 1 week of wear, replacing lenses daily

Questions about this trial

What is this clinical trial studying?

A study testing Delefilcon A contact lens and Etafilcon A contact lens in people with Myopia, run by CIBA VISION.

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 7 inclusion and 7 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 3 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

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 3 Aug 2012). 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?

Corrected Distance Monocular Visual Measurement Reported as Visual Acuity (VA) (time frame: 1 week of wear, replacing lenses daily). 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 3 Aug 2012.
