Who cannot join

  • Patients with any anterior segment pathology (anterior segment or corneal abnormalities, chronic uveitis, iritis, corneal dystrophy, pseudoexfoliation, etc.).

  • Patients who require chronic administration of any topical ophthalmic or systemic medication that may affect accommodation such as mydriatic, cycloplegic and myotic agents; tricyclic antidepressants, phenothiazines, benzodiazepines, first generation antihistamines, anticholinergic agents. The use of tamsulosin hydrochloride (Flomax®) is also excluded preoperatively due to floppy iris syndrome.
  • Patients with best corrected visual acuity of 20/80 or worse in the fellow eye not attributable to cataract.

What participants receive

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

  • Standard Monofocal Intraocular LensDevice

    The control (active comparator) arm is comprised of patients who meet all study eligibility criteria and will be implanted with a standard monofocal intraocular lens.

    Each study patient will undergo standard extracapsular cataract extraction through a clear corneal or limbal incision and circular continuous curvilinear capsulorhexis.

  • Synchrony® Dual Optic Intraocular LensDevice

    The Synchrony® Dual Optic Intraocular Lens (experimantal) arm is comprised of patients who meet all study eligibility criteria and will be implanted with a Synchrony® Dual Optic Intraocular Lens.

    Each study patient will undergo standard extracapsular cataract extraction through a clear corneal or limbal incision and circular continuous curvilinear capsulorhexis.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Standard Monofocal Intraocular Lens and Synchrony® Dual Optic Intraocular Lens in people with Cataract, run by Abbott Medical Optics at 20 sites 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 7 inclusion and 10 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: stopped early, as of the sponsor's last update on 19 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 was stopped early. Results are not available in the source record.

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?

Distance corrected near visual acuity (time frame: 1 Mo, 4-6 Mo, 12 Mo, 24 Mo, & 36 Mo). 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 19 Sep 2013.
