About this study

Official title: A Multicenter Clinical Evaluation of the Clinical Performance of a Phakic Intraocular Lens

This study will evaluate the clinical performance of a phakic intraocular lens (IOL) for the improvement of Uncorrected Near Visual Acuity (UCNVA) in subjects who require between +1.00 and +2.50 Reading Add.

Read the detailed description

This is a prospective, open-labeled, multi-site evaluation of clinical performance of the STAAR EVO+ Visian™ Implantable Collamer® Lens (VICL) with Aspheric (EDOF) Optic [EDOF ICL] for the improvement of UCNVA in subjects who require between +1.00 and +2.50 Reading Add.

Approximately 48 subjects who meet all eligibility criteria will undergo EDOF ICL implantation in both eyes. All eyes will be followed for 6 months after surgery.

The first eye implanted with the study lens and the appropriate time for fellow eye implantation will be determined by the medical judgement of the Investigator. All eyes will be analyzed for safety and performance.

The primary performance endpoint is defined as achievement of monocular UCNVA of Snellen equivalent 20/40 or better at 40 cm at 6 months after implantation in equal to or greater than 75% of implanted eyes.

What participants receive

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

  • EDOF ICLDevice

    Also called EVO+ Visian ICL with Aspheric (EDOF) Optic

    The Visian ICL is intended to be implanted within the posterior chamber, directly behind the iris, and in front of the anterior capsule of the human crystalline lens. It offers an intraocular alternative for the correction of refractive error in those who currently utilize spectacle and/or contact lenses correction.

Questions about this trial

What is this clinical trial studying?

A study testing EDOF ICL in people with Presbyopia, run by Staar Surgical Company at 6 sites in 2 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 16 inclusion and 13 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 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Spain, Belgium. 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 Sep 2022). 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?

Number of Eyes With Monocular Uncorrected Near Visual Acuity of 20/40 or Better at 40 cm 6 Months After Implantation (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03499821, which also lists 1 linked publication.

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 Mar 2026.
