About this study

Official title: Evaluation of the Visual Acuity After the Implantation of a ReSTOR +2.5 Diopters Intraocular Lens (ReSTOR SV25T0) in the Distance Dominant Eye, in Combination With a +3.0 Diopters ReSTOR Intraocular Lens (ReSTOR SN6AD1) in the Fellow Eye.

The objective of this study is to assess the visual outcome after the combined binocular implantation of +2.5 D and +3.0 D apodized diffractive multifocal intraocular lenses.

Read the detailed description

Bifocal multifocal intraocular lenses (MIOL) are effective in achieving good uncorrected visual acuities in the distance and the near. However, the intermediate vision is of increasing relevance for everyday's life. Several multifocal intraocular lenses have been developed to improvement intermediate vision. Nonetheless, those systems still possess adverse photic effects and do not garantuee spectacle independence. Therefore, the combination of a lower-addition bifocal intraocular lense in the distance-dominant eye with a higher-addition bifocal intraocular lense in the fellow-eye might be a promising approach to address these drawbacks of current binocular and trifocal intraocular lenses.

What is being measured

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

  1. Visual acuities in the far, intermediate and near

    Visual acuities are tested under photopic conditions at 5 m, intermediate (80 cm) and patient-preferred near distance (≈ 40 cm).

    Measured: 1 month

  2. Visual acuities in the far, intermediate and near

    Visual acuities are tested under photopic conditions at 5 m, intermediate (80 cm) and patient-preferred near distance (≈ 40 cm).

    Measured: 3 months

  3. Mesopic vision

    Mesopic visual acuities are tested under high-contrast, low-contrast and low-contrast with glare.

    Measured: 1 month

  4. Mesopic vision

    Mesopic visual acuities are tested under high-contrast, low-contrast and low-contrast with glare.

    Measured: 3 months

  5. Scotopic contrast sensitivity

    Scotopic contrast sensitivity are tested at 0.1 cd/m2, 0.032 cd/m2 and 0.1 cd/m2 with glare.

    Measured: 1 month

  6. Scotopic contrast sensitivity

    Scotopic contrast sensitivity are tested at 0.1 cd/m2, 0.032 cd/m2 and 0.1 cd/m2 with glare.

    Measured: 3 months

Secondary outcomes (1)

  1. Spectacle independence in the far, intermediate and near

    Spectacle independence as stated by the patient.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Binocular cataract surgery with phacoemulsification and implantation of multifocal intraocular lenses in people with Cataract, run by Charite University, Berlin, Germany at 1 site in Germany.

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 5 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 16 Dec 2015. 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 Germany. 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?

Visual acuities in the far, intermediate and near (time frame: 1 month). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02314572, which also lists 6 linked publications.

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 16 Dec 2015.
