About this study

The purpose of this study is to evaluate the effect that placement and power of the AcrySof Toric has on post-operative visual acuity and spectacle independence for distance vision. This will be determined by comparing manifest refraction pre-operatively and post-operatively and by evaluating the rotational stability of the lens over time.

What is being measured

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

  1. Visual Acuity (VA)

    Pre-operative and 1 month, 3 month, and 6 month post-operative visual acuity (VA) measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).

    Measured: Pre-operative, 1 month, 3 month, and 6 month post-operative

Secondary outcomes (2)
  1. Spectacle Independence

    Percentage of subjects reporting that they never wear glasses at the 6 month post-operative visit

    Measured: 6 months post-operative

  2. IOL Rotation

    Evaluation of percentage of patients that experienced rotation of the intraocular lens (IOL) less than or equal to 5 degrees from initial implantation, and less than or equal to 10 degrees from initial implantation.

    Measured: 6 months post-operative

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing AcrySof Toric IOL 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 8 inclusion and 23 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 16 Jan 2012. 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 7 Apr 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 (VA) (time frame: Pre-operative, 1 month, 3 month, and 6 month post-operative). 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 16 Jan 2012; AzTrials last refreshed its copy on 31 Oct 2026.
