What is being measured

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

  1. Initial comfort

    Initial Comfort (within 10-15 minutes of lens insertion) will be assessed bilaterally by the participant at time of dispense. Initial Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

    Measured: Baseline

Secondary outcomes (3)
  1. End of Day Comfort

    End of Day Comfort will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. End of Day Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

    Measured: Day 7

  2. Overall Comfort

    Overall Comfort will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. Overall Comfort will be graded on a 1-10 scale (10=cannot be felt, 1=painful).

    Measured: Day 7

  3. Overall Handling at Time of Removal

    Overall Handling at Time of Removal will be assessed by the participant as a retrospective, bilateral evaluation of 1 week of wear. Overall Handling at Time of Removal will be graded on a 1-10 scale (10=excellent, very easy; 1=unmanageable).

    Measured: Day 7

Questions about this trial

What is this clinical trial studying?

A study testing Nelfilcon A contact lens and UltraFilcon B contact lens in people with Refractive Error, run by Alcon Research at 1 site in United Kingdom.

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 8 inclusion and 9 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 7 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Initial comfort (time frame: Baseline). 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 7 Nov 2013.
