About this study

Official title: Pilot Clinical Investigation of Adaptive Eyeglasses for the Correction of Presbyopia

This study is a pilot clinical investigation of adaptive eyeglasses for the correction of presbyopia. The goal of this clinical investigation is to assess IMD safety and to obtain patient feedback on the usefulness of the Laclarée eyeglasses, through subjective clinical measures and qualitative evaluations. This is an exploratory investigation.

Read the detailed description

Presbyopia is a visual impairment caused by the normal aging of the eye lens and resulting in progressive loss of accommodation. As a consequence, from the onset of presbyopia occurring around 40-45 years old, the eye has growing trouble focusing at near and intermediate distances. Millions of presbyopes encounter difficulties with current corrective solutions, leading to vision and postural discomfort. Laclarée's adaptive eyeglasses are providing an alternative solution, closer to the native crystalline accommodation. Besides an enhanced field-of-view, these eyeglasses offer a disruptive ergonomics where the glasses automatically adjust to the wearer's need to provide clear vision at all distances and can be electronically recalibrated to adjust the delivered addition throughout presbyopia.

What participants receive

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

  • Prototype of adaptive eyeglassesDevice

    The tested investigational medical device is a prototype of semi-integrated eyeglasses.

  • ComparatorDevice

    The comparator is either a pair of progressive lenses that provide clear vision at both distance and near vision, either, for wearers who have rejected progressive glasses, an alternative solution providing clear vision at both distance and near vision which can consist of bifocal glasses, multifocal or monovision lenses, multiple pairs of glasses or one pair for cases of emmetropia.

What is being measured

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

  1. IMD safety evaluation

    To evaluate the IMD safety : Collection of adverse events.

    Measured: 2 hours

Secondary outcomes (3)
  1. Exploratory evaluation of the IMD - controlled tests assessing visual acuity and performance on visual tasks

    To make an exploratory evaluation of the IMD performance on patient vision quality, when compared to that obtained with the patient usual personal eyewear (comparator) : Subjective measures on controlled tests assessing visual acuity and performance on visual tasks.

    Measured: 2 hours

  2. Exploratory evaluation of the IMD - a questionnaire assessing vision quality

    To make an exploratory evaluation of the IMD performance on patient vision quality, when compared to that obtained with the patient usual personal eyewear (comparator) : Subjective measures on questionnaires.

    Measured: 2 hours

  3. Exploratory evaluation of the IMD - patient qualitative feedback

    To make an exploratory evaluation of the IMD performance on patient vision quality, when compared to that obtained with the patient usual personal eyewear (comparator) : Collection of patient feedback.

    Measured: 2 hours

Questions about this trial

What is this clinical trial studying?

A study testing Prototype of adaptive eyeglasses and Comparator in people with Presbyopia, run by Laclaree at 1 site in France.

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 15 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 13 Apr 2022. 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 France. 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.

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?

IMD safety evaluation (time frame: 2 hours). 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 13 Apr 2022.
