About this study

Official title: Prospective Evaluation of Visual Outcomes With Tecnis One-Piece Multifocal Intraocular Lenses Compared With Patients Previously Implanted With Crystalens AO

The study is being conducted to collect information about visual outcomes and participant satisfaction with the Tecnis One-Piece Multifocal (MF) Intraocular Lenses (IOLs) compared with participants previously implanted with Crystalens Aspheric Optic (AO) IOLs. The U.S. Food and Drug Administration (FDA) has cleared the Tecnis One-Piece MF IOL for visual correction of aphakia (replacing a removed lens in the eye) in adults.

Being tested
Tecnis one-piece MF IOL, Crystalens AO

What participants receive

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

  • Tecnis one-piece MF IOLDevice

    25 patients to be implanted after cataract surgery

  • Crystalens AODevice

    25 patients that are previously implanted

Crystalens AONo interventionIt is planned that about 25 people who are at least 18 years old and have been implanted with Crystalens AO
Receives: Device: Crystalens AO

What is being measured

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

  1. Incision size

    Part 1 Only:

    The primary outcome measure is incision size at three points:

    Immediately after application of the keratome blade Post phacoemulsification Post Tecnis IOL implantation Target refraction vs. achieved

    Part 1 and 2:

    UCVA data at distance, intermediate, and near Near vision will be measured in mesopic and photopic conditions standardized with light meter BCVA at distance and near Enhancement rates Spectacle independence questionnaire and patient satisfaction Incidence of adverse events

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Tecnis one-piece MF IOL and Crystalens AO in people with To Collect Information About Visual Outcomes and Participant Satisfaction, run by Innovative Medical 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 16 inclusion and 26 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 14 Jun 2012. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Incision size (time frame: 1 year). 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 14 Jun 2012.
