Who may be able to join

  • Patients must have a clinically documented diagnosis of bilateral cataract (either cortical, nuclear, subcapsular or a combination) liable to benefit from standard cataract surgery.

What is being measured

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

  1. Low Contrast Best Corrected Visual Acuity Following Cataract Surgery

    Low contrast best corrected visual acuity (ability to distinguish objects on a similarly colored or shaded background) 3 months following cataract surgery.

    Measured: 3 months

  2. Low Contrast Uncorrected Visual Acuity Following Cataract Surgery

    Low contrast uncorrected visual acuity 3 months post cataract surgery

    Measured: 3 months

  3. Photopic Contrast Sensitivity

    The mean photopic (day light) contrast sensitivity for each spatial frequency (cycle per degree-CPD) (1.5, 3.0, 6.0, 12.0 and 18 cpd)

    Measured: 3 months

  4. Mesoptic Contrast Sensitivity

    The mean mesoptic (low light) contrast sensitivity for each spatial frequency (cycle per degree-CPD) (1.5, 3.0, 6.0, 12.0 and 18 cpd)

    Measured: 3 Months

  5. Posterior Capsule Opacification Score

    Posterior Capsule Opacification Score (PCO), Density of opacification measured from 0-4 (1=minimal and 4=severe) and area of opacification measured from 0-1 (0=no opacification and 1=posterior capsule opacification required a treatment). Results (EPCO) were computer calculated by multiplying density by area of opacification.

    Measured: 24 months

Secondary outcomes (12)
  1. High Contrast Visual Acuity

    High contrast visual acuity (ability to distinguish objects of contrasting color such as black on white) uncorrected and best corrected visual acuity.

    Measured: 1 month

  2. High Contrast Visual Acuity Uncorrected

    Measured: 3 months

  3. High Contrast Visual Acuity Best Corrected

    Measured: 3 months

  4. High Contrast Visual Acuity

    Measured: 12 months

  5. High Contrast Visual Acuity Uncorrected

    Measured: 24 Months

  6. High Contrast Visual Acuity Best Corrected

    Measured: 24 Months

  7. Low Contrast Visual Acuity

    Uncorrected Low contrast visual acuity - LogMar visual acuity value

    Measured: 1 month

  8. Contrast Sensitivity Photopic 1.5cpd

    The mean photopic (day light) contrast sensitivity were to be compared between both IOLs for each special frequency (1.5, 3.0, 6.0, 12.0 and 18 cpd)

    Measured: 1 month

  9. Contrast Sensitivity Photopic

    The mean photopic (day light) contrast sensitivity were to be compared between both IOLs for each special frequency (1.5, 3.0, 6.0, 12.0 and 18 cpd)

    Measured: 1 month

  10. Contrast Sensitivity Mesoptic 1.5 Cpd

    The mean mesopic (dim light) contrast sensitivity were to be compared between both IOLs for each special frequency (1.5, 3.0, 6.0, 12.0 and 18 cpd)

    Measured: 1 month

  11. Contrast Sensitivity Mesoptic

    The mean mesopic (dim light) contrast sensitivity were to be compared between both IOLs for each special frequency (1.5, 3.0, 6.0, 12.0 and 18 cpd)

    Measured: 1 month

  12. Posterior Capsule Opacification

    Posterior Capsule Opacification Score (PCO), Density of opacification measured from 0-4 (1=minimal and 4=severe) and area of opacification measured from 0-1 (0=no opacification and 1=posterior capsule opacification required a treatment). Results (EPCO) were computer calculated by multiplying density by area of opacification.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Advanced Akreos Adapt in one operated eye. and Akreos Adapt in fellow operated eye. in people with Cataract, run by Bausch & Lomb Incorporated.

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 2 inclusion and 3 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 12 Dec 2011. 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.

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?

Yes. Results are posted in the registry (first posted 5 Jan 2011). 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?

Low Contrast Best Corrected Visual Acuity Following Cataract Surgery (time frame: 3 months). The study lists 5 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 12 Dec 2011.
