About this study

The primary purpose of this study is to evaluate the long-term (3 years) visual acuity and adverse event outcomes for the Clareon® Intraocular Lens (IOL). A comparison to historical safety and performance endpoint (SPE) rates as reported in the European Standard International Organization for Standardization (EN ISO) 11979-7:2014 will be conducted at one year. The secondary purpose of this study is to evaluate the visual acuity outcomes with the Clareon IOL at Years 2 and 3.

Read the detailed description

Subjects will attend a total of 12 study visits over a period of approximately 36 months: One preoperative screening visit, two operative visits, and nine post-implantation visits. Both eyes will be implanted, with the second eye implantation to occur 2-21 days after the first. Primary endpoint data will be collected at the Year 1 visit (Day 330-420 post-implantation from second eye surgery).

What is being measured

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

  1. Percentage of First Implanted Eyes Achieving Best-Corrected Distance Visual Acuity (BCDVA) of 0.3 Logarithm Minimum Angle of Resolution (logMAR) or Better at 1 Year Post-Implantation

    Visual acuity (VA) was tested for the first implanted eye using the correction obtained from the manifest refraction and 100% contrast electronic Early Treatment Diabetic Retinopathy Study (ETDRS) charts at a distance of 4 meters (m) from the eye. VA was measured in logarithm of the minimum angle of resolution (logMAR), with 0.02 logMAR increment corresponding to a single letter on an ETDRS chart. A BCDVA of 0.3 logMAR is equivalent to 20/40 Snellen visual acuity. VA was compared to the historical safety and performance endpoint (SPE) of 92.5% [as reported in the European Standard International Organization for Standardization (EN ISO) 11979-7:2014].

    Measured: Year 1 post-implantation from second eye surgery

  2. Percentage of Second Implanted Eyes Achieving BCDVA of 0.3 logMAR or Better at 1 Year Post-Implantation

    VA was tested for the second implanted eye using the correction obtained from the manifest refraction and 100% contrast electronic ETDRS charts at a distance of 4 m from the eye. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter on an ETDRS chart. A BCDVA of 0.3 logMAR is equivalent to 20/40 Snellen visual acuity. VA was compared to the historical SPE of 92.5% (EN ISO 11979-7:2014).

    Measured: Year 1 post-implantation from second eye surgery

Secondary outcomes (10)
  1. Percentage of First Implanted Eyes Achieving BCDVA of 0.3 logMAR or Better at 2 Years Post-Implantation

    VA was tested for the first implanted eye using the correction obtained from the manifest refraction and 100% contrast electronic ETDRS charts at a distance of 4 m from the eye. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter on an ETDRS chart. A BCDVA of 0.3 logMAR is equivalent to 20/40 Snellen visual acuity. No hypothesis testing was prespecified for this endpoint.

    Measured: Year 2 post-implantation from second eye surgery

  2. Percentage of Second Implanted Eyes Achieving BCDVA of 0.3 logMAR or Better at 2 Years Post-Implantation

    VA was tested for the second implanted eye using the correction obtained from the manifest refraction and 100% contrast electronic ETDRS charts at a distance of 4 m from the eye. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter on an ETDRS chart. A BCDVA of 0.3 logMAR is equivalent to 20/40 Snellen visual acuity. No hypothesis testing was prespecified for this endpoint.

    Measured: Year 2 post-implantation from second eye surgery

  3. Percentage of First Implanted Eyes Achieving BCDVA of 0.3 logMAR or Better at 3 Years Post-Implantation

    VA was tested for the first implanted eye using the correction obtained from the manifest refraction and 100% contrast electronic ETDRS charts at a distance of 4 m from the eye. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter on an ETDRS chart. A BCDVA of 0.3 logMAR is equivalent to 20/40 Snellen visual acuity.

  4. Percentage of Second Implanted Eyes Achieving BCDVA of 0.3 logMAR or Better at 3 Years Post-Implantation

    VA was tested for the second implanted eye using the correction obtained from the manifest refraction and 100% contrast electronic ETDRS charts at a distance of 4 m from the eye. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter on an ETDRS chart. A BCDVA of 0.3 logMAR is equivalent to 20/40 Snellen visual acuity. No hypothesis testing was prespecified for this endpoint.

    Measured: Year 3 post-implantation from second eye surgery

  5. Uncorrected Distance Visual Acuity (UCDVA) at 1 Year Post-Implantation - First Implanted Eye

    VA was tested for the first implanted eye without visual correction using 100% contrast electronic ETDRS charts at a distance of 4 m from the eye. +0.25 diopter (D) spherical power was applied to correct for optical infinity.

Questions about this trial

What is this clinical trial studying?

A study testing Clareon® IOL and Cataract Surgery in people with Cataract and Aphakia, run by Alcon Research at 19 sites in 7 countries.

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 3 inclusion and 4 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 21 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites in Spain, Australia, France, United Kingdom, Germany and 2 more countries. 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?

Yes. Results are posted in the registry (first posted 21 Aug 2023). 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?

Percentage of First Implanted Eyes Achieving Best-Corrected Distance Visual Acuity (BCDVA) of 0.3 Logarithm Minimum Angle of Resolution (logMAR) or Better at 1 Year Post-Implantation (time frame: Year 1 post-implantation from second eye surgery). The study lists 2 primary outcomes in all. 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 21 Aug 2023.
