What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AcrySof IQ Toric IOLDevice

    Also called AcrySof IQ Toric IOL Model SN6AT3, AcrySof IQ Toric IOL Model SN6AT4, AcrySof IQ Toric IOL Model SN6AT5

    AcrySof IQ Toric intraocular lens implanted in the capsular bag of the eye during cataract surgery. The IOL is intended for the lifetime of the patient.

  • AcrySof IQ Aspheric IOLDevice

    Also called AcrySof IQ Aspheric IOL Model SN60WF

    AcrySof IQ aspheric intraocular lens implanted in the capsular bag of the eye during cataract surgery. The IOL is intended for the lifetime of the patient.

  • Limbal Relaxing Incision (LRI)Procedure or surgery

    An incision was made at the corneal-limbal junction during cataract surgery for the purpose of relaxing corneal curvature, ie., correcting astigmatism.

Questions about this trial

What is this clinical trial studying?

A study testing AcrySof IQ Toric IOL, AcrySof IQ Aspheric IOL and Limbal Relaxing Incision (LRI) in people with Cataract and Astigmatism, 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 5 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 Nov 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.

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?

Corneal Aberration (time frame: Month 6 postoperative). 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 Nov 2012.
