What is being measured

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

  1. Mean Investigator-Rated Lens Centration

    Lens centration was assessed by the investigator using slit-lamp microscopy and rated on a 5-point scale, where 0=Optimal and 4=Severe decentration. Both eyes contributed to the mean.

    Measured: After 1 week of wear

Secondary outcomes (3)
  1. Mean Investigator-Rated Lens Fit

    Lens fit was assessed by the investigator and rated on a 5-point scale with -2=Unacceptable tight fit, -1=Acceptable tight fit, 0=Optimal, 1=Acceptable loose fit, and 2=Uacceptable loose fit. Both eyes contributed to the mean.

    Measured: After 1 week of wear

  2. Average Subjective Ratings Score (Lens Handling and Overall Vision)

    The participant rated the handling and overall vision of the contact lenses on a 10-point scale, where 10=Excellent and 1=Poor. Both eyes contributed to the mean.

    Measured: After 1 week of wear

  3. Average Subjective Ratings Score (Lens Wearing Conditions and Visual Performance During Ball Sports)

    The participant rated the lens wearing conditions and visual performance of the contact lenses during ball sports on a 10-point scale, where 10=Agree and 1=Disagree. "Overall Vision" was rated with 10=Excellent and 1=Poor. Both eyes contributed to the mean.

    Measured: After 1 week of wear

Questions about this trial

What is this clinical trial studying?

A study testing Nelfilcon A contact lenses and Etafilcon A contact lenses in people with Refractive Error and Myopia, run by Alcon Research.

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 5 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 29 Oct 2014. 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 29 Oct 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?

Mean Investigator-Rated Lens Centration (time frame: After 1 week of wear). 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 29 Oct 2014.
