What is being measured

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

  1. Visual Acuity

    Uncorrected Visual Acuity (VA) is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.

    Measured: 6 months

Secondary outcomes (3)
  1. Contrast Sensitivity

    Contrast sensitivity is the measurement of one's ability to detect slight changes in luminance before it becomes indistinguishable. It is measured in logarithmic (log) units by means of an illuminated box, the CSV 1000 by Vector Vision. A higher value for the logarithmic units translates to better contrast sensitivity.

    Measured: 6 Months

  2. Patient Satisfaction

    Average rating of patient satisfaction based on a patient survey. The survey had a 10 point scale (10 being most satisfied and 0 being most unsatisfied).

    Measured: 6 Months Postoperative

  3. Spectacle Independence

    The percentage of patients reporting spectacle independence (no longer needing to wear glasses).

    Measured: 6 Months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ReSTOR in people with Cataracts, run by Alcon Research at 1 site 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 2 inclusion and 2 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 23 Mar 2010. 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 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 16 Mar 2010). 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?

Visual Acuity (time frame: 6 months). 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 23 Mar 2010.
