Trial summary

To evaluate the safety and effectiveness of the ZM900 Tecnis Multifocal lens. Results from two studies (an original study with 125 multifocal and 123 monofocal subjects, protocol DIOL-101-TCNS, and an expansion study with 222 additional multifocal subjects, protocol DIOL-104-TCNS) are combined to evaluate the ZM900… Read more about this study

  • Adult, Older adult

Who may be able to join

  • Visual potential of 20/30 or better in each study eye

About this study

Official title: Clinical Evaluation of the Tecnis Multifocal Intraocular Lens (IOL), Model ZM900, Original Study (DIOL-101-TCNS); Clinical Evaluation of the Tecnis Multifocal Intraocular Lens, Model ZM900, Expansion Study (DIOL-104-TCNS)

To evaluate the safety and effectiveness of the ZM900 Tecnis Multifocal lens. Results from two studies (an original study with 125 multifocal and 123 monofocal subjects, protocol DIOL-101-TCNS, and an expansion study with 222 additional multifocal subjects, protocol DIOL-104-TCNS) are combined to evaluate the ZM900 Tecnis Multifocal lens vs. a monofocal control. The original study was conducted in 2004-2006; the expansion study was conducted in 2007-2008. Results from both studies were analyzed together for FDA approval.

Read the detailed description

The original study was protocol DIOL-101-TCNS; the expansion study was protocol DIOL-104-TCNS. The study protocols were almost identical with the exception that no control subjects were enrolled in the expansion study; only additional multifocal subjects. All eligibility criteria and testing conducted in the expansion study was the same as that in the original study. The hypotheses were that best corrected distance visual acuity of the ZM900 lens would meet or exceed the FDA grid values, complication and adverse event rates of the ZM900 would be similar to the FDA grid rates for posterior chamber IOLs, and near visual acuity of the ZM900 lens would be improved compared to that of the monofocal control lens.

Tecnis Multifocal IOL groupExperimentalSubjects implanted bilaterally with the Tecnis Multifocal IOL. Participants were enrolled in this arm in the original study and also in the expansion study. Outcomes of the first eye of each subject were analyzed for the primary study endpoints.

Receives: Device: CeeOn 911A monofocal IOL

What is being measured

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

  1. Number of Participants That Achieved Best Corrected Distance Visual Acuity of 20/40 or Better in the First Eye.

    Number of participants that achieved a best corrected distance visual acuity of 20/40 or better in the first eye. As most subjects were implanted bilaterally,"first eye" refers to the first implanted eye of each subject.

    Measured: One year

  2. Mean Binocular Distance Corrected Near Visual Acuity in Snellen

    Mean binocular near visual acuity with distance correction in place measured at 33 cm; Mean is reported in Snellen (e.g. 20/20, 20/40, etc.), standard deviation reported in ETDRS (Early treatment diabetic retinopathy study)eye chart log units.

    Measured: One year

Questions about this trial

What is this clinical trial studying?

A study testing Tecnis ZM900 Multifocal Intraocular Lens and CeeOn 911A monofocal IOL in people with Cataract, run by Abbott Medical Optics.

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 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 4 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

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 2 Dec 2010). 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 Participants That Achieved Best Corrected Distance Visual Acuity of 20/40 or Better in the First Eye. (time frame: One year). 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 4 Feb 2025.
