About this study

Official title: Clinical and Functional Performance of Acrysof IQ Vivity Versus Aspheric Monofocal IOLs

The purpose of the study is to evaluate clinical and functional performance in real-world conditions in participants who have been implanted with Acrysof IQ Vivity (Extended Vision) IOLs compared with Alcon Aspheric Monofocal IOLs.

Read the detailed description

This observational study will enroll subjects who have been implanted with an Alcon aspheric monofocal or monofocal toric IOL no less than 4 months prior to study procedures. This study will be conducted in Australia.

Conditions
Visual Acuity
Being tested
Vivity IOL, Aspheric monofocal IOL

What is being measured

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

  1. Binocular photopic best-corrected distance visual acuity (BCDVA)

    Visual acuity will be measured using a standard visual acuity chart at a distance of 4 meters under photopic (well-lit) conditions and reported in logarithm Minimum Angle of Resolution (logMAR) units. Visual acuity will be measured binocularly (both eyes together).

    Measured: At least 4 months post-operative

Questions about this trial

What is this clinical trial studying?

An observational study of Visual Acuity, run by Alcon Research at 1 site in Australia.

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 4 inclusion and 3 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 9 Jul 2024. 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 Australia. 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?

Binocular photopic best-corrected distance visual acuity (BCDVA) (time frame: At least 4 months 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 9 Jul 2024.
