What is being measured

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

  1. Binocular Distance Corrected Near Visual Acuity at Best Distance (That Which Provides the Subject With the Best Vision)

    Binocular Distance Corrected Near Visual Acuity at Best Distance (that which provides the subject with the best vision)measured in mean logMAR. logMAR is the logarithm of the minimum angle of resolution, which is a measure for visual acuity (VA). Mean logMAR is the average value of visual acuity.

    Measured: 3 months

Secondary outcomes (4)
  1. Binocular Distance Corrected Distance Visual Acuity

    Binocular Distance Corrected Distance Visual Acuity measured in logMAR. LogMAR is the logarithm of the minimum angle of resolution, which is a measure for visual acuity (VA).

    Measured: 3 months post-operative

  2. Binocular Distance Corrected Intermediate Visual Acuity (Tested at 50 cm)

    Binocular Distance Corrected Intermediate Visual Acuity (tested at 50 cm) measured in logMAR. LogMAR is the logarithm of the minimum angle of resolution, which is a measure for visual acuity (VA).

    Measured: 3 months post-operative

  3. Binocular Distance Corrected Intermediate Visual Acuity (Tested at 60 cm)

    Binocular Distance Corrected Intermediate Visual Acuity (tested at 60 cm)measured in logMAR. LogMAR is the logarithm of the minimum angle of resolution, which is a measure for visual acuity (VA).

    Measured: 3 months post-operative

  4. Binocular Distance Corrected Intermediate Visual Acuity (Tested at 70 cm)

    Binocular Distance Corrected Intermediate Visual Acuity (tested at 70 cm) measured in logMAR. LogMAR is the logarithm of the minimum angle of resolution, which is a measure for visual acuity (VA).

    Measured: 3 months post-operative

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ACRYSOF® ReSTOR® Aspheric +4.0 D Add Power Intraocular Lens and ACRYSOF® ReSTOR® Aspheric +3.0 D Add Power Intraocular Lens in people with Cataract, 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 9 inclusion and 20 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 13 Jul 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 11 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?

Binocular Distance Corrected Near Visual Acuity at Best Distance (That Which Provides the Subject With the Best Vision) (time frame: 3 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 13 Jul 2010.
