Trial summary

Current visual outcomes expectations of cataract patients are similar to those of refractive surgery patients. Their desire is to be spectacle independent for far, intermediate and near vision activities. Some may have already enjoyed freedom from glasses and would like to continue after the cataracts are removed. Read more about this study

About this study

Official title: Visual Outcomes of an Extended Depth of Focus (EDOF) Intraocular Lens (IOL) Combined With a Multifocal (MF) IOL

Current visual outcomes expectations of cataract patients are similar to those of refractive surgery patients. Their desire is to be spectacle independent for far, intermediate and near vision activities. Some may have already enjoyed freedom from glasses and would like to continue after the cataracts are removed. Different options are available. These options include: mono-vision and presbyopia correcting intraocular lenses (IOL). Presbyopia correcting IOLs include accommodative, multifocals and extended depth of focus (EDOF) IOLs. In a previous study, the visual outcomes of the EDOF Toric IOL were evaluated when both eyes were targeted for plano and when the non-dominant eye was set for a small residual myopic error (-0.50 D) or nanovision in patients with astigmatism. The nanovision approach, appeared to provide similar binocular acuity at distance and intermediate but better acuity at near. The purpose of this study is to evaluate the visual outcomes of an EDOF IOL when combined with a multifocal IOL with a +3.25 D add in patients with or without astigmatism undergoing routine cataract surgery.

What participants receive

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

Tecnis ZLB00 & Symfony IOLExperimentalThe Tecnis multifocal ZLB00 and the Symfony IOLs are presbyopia correcting lenses designed to improve the vision at distance, intermediate and near reducing the need for glasses in patients undergoing cataract surgery.
Receives: Device: Tecnis ZLB00 & Symfony IOL

What is being measured

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

  1. Binocular Uncorrected Near (40 cm) Visual Acuity.

    Visual acuity measured at 40 cm without wearing any correction.

    Measured: 3 months

Secondary outcomes (3)
  1. Patient Visual Satisfaction After Cataract Surgery: Questionnaire

    Patient's overall satisfaction with their vision after cataract surgery assessed by asking the following question: "Taking all things into account, how satisfied or dissatisfied are you with your vision WITHOUT glasses or contacts with your near vision". Possible answers are: Completely satisfied and mostly satisfied, moderately satisfied, a little satisfied or not at all satisfied.

    Measured: 3 months

  2. Spectacle Independence: Questionnaire

    Patient's spectacle independence was assessed using the "Patient Reported Spectacle Independence Questionnaire (PRSIQ) which includes the following questions: 1. During the LAST 7 DAYS, did you need glasses or contacts for near. Possible answers: Yes No.

    Measured: 3 months

  3. Number of Participants With Visual Symptoms

    Number of participants who reported any visual disturbances or symptoms. One participant could report more than one symptom.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Tecnis ZLB00 & Symfony IOL in people with Cataract Bilateral and Presbyopia, run by Carolina Eyecare Physicians, LLC 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 6 inclusion and 19 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 10 Aug 2020. 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?

Yes. Results are posted in the registry (first posted 10 Aug 2020). 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?

Binocular Uncorrected Near (40 cm) Visual Acuity. (time frame: 3 months). 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 10 Aug 2020.
