About this study

Official title: Performance of Two Non-diffractive Intraocular Lenses With Extended Depth of Vision Set for Mini-monovision

Comparison of the capsular bag performance of two extended depth of vision (EDOF) intraocular lenses (IOLs), the Rayone EMV and the Alcon Acrysof IQ Vivity, in a mini-monovision setting

Read the detailed description

Spectacle independence is a rising aim in modern cataract surgery. Although bilateral monofocal IOL implantation, aiming for emmetropia leads to high levels of patient satisfaction for distance vision, spectacle dependence for reading and intermediate vision tasks is the usual result.

The option commonly used to achieve spectacle independence in all distances are multifocal intraocular lenses. One concept of multifocality is the trifocal lens. This lens provides good vision in three focal distances: far, intermediate, and near. However, one potential disadvantage of trifocal IOLs is slightly poorer near vision with need for reading gasses for prolonged fine near work and loss of contrast sensitivity in the intermediate distance.

A better intermediate performance concerning contrast vision compared to trifocal IOLs can be reached using enhanced depth of focus (EDOF) lenses. These IOLs have an extended far focus area, which reaches to the intermediate distance, providing high-quality vision over a continuous range of focus, rather than distinct foci with blur in between. In the last years several technologies for EDOF IOLs appeared on the market. The disadvantage compared to monofocal lenses in all of these technologies is the potentially worse contrast sensitivity as well as dysphotopsia.

A new monofocal non-diffractive lens with an extended depth of vision (Rayone EMV) promises an increased range of functional vision and less dysphotopsias. Especially in a monovision setting, where the dominant eye is set for emmetropia and the other eye for low myopia is believe dto be a promising concept for spectacle independence.

Hence, the aim of this study is to compare a new monofocal IOL wit a non-diffractive extended depth of vision (Rayone EMV) with an already established non-diffractive EDOF IOL (Alcon Acrysof IQ Vivity) in a mini-monovision setting.

96 eyes of 48 patients will be included into this study. After randomization, each patient will either receive the Rayone EMV or the Alcon Acrysof IQ Vivity in both eyes. Follow-up visits will be 2 weeks and 3 months after surgery. During these visits a slitlamp examination, measurement of the intraocular pressure, visual acuity assessment, pupil size measurement, determination of the defocus curve, contrast sensitivity measurements, reading speed detection, and a flaremeter measurement will be performed.

What is being measured

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

  1. Visual acuity at intermediate distance

    The visual acuity at the intermediate distance will be measured using ETDRS charts at a distance of 80 centimetres and compared between the two different IOLs

    Measured: 24 months

Secondary outcomes (6)
  1. Visual acuity at far distance

    The visual acuity at the far distance will be measured using ETDRS charts at a distance of 4 metres and compared between the two different IOLs

    Measured: 24 months

  2. Visual acuity at near distance

    The visual acuity at the near distance will be measured using ETDRS charts at a distance of 40 centimetres and compared between the two different IOLs

    Measured: 24 months

  3. Visual acuity in the defocus curve

    The visual acuity in the defocus curve will be measured using ETDRS charts at 4 metres with the patient wearing glasses in the power range of -3.5 to +1.0 diopters (presented in 0.5 dioptre steps) and will be compared between the two IOLs

    Measured: 24 months

  4. Halometry

    The size of the halos depicted in degrees will be assessed using the aston halometer and will be compared between the two IOLs

    Measured: 24 months

  5. Contrast sensitivity

    Contast sensitvity will be measured using the Optec Vision tester and will be compared between the two IOLs

    Measured: 24 months

  6. Reading speed

    Reading speed will be assessed with teh Salzburg Reading Desk and will be compared between the two different IOLs

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A study testing non-diffractive monofocal IOL and standard EDOF IOL in people with Cataract Senile, run by Vienna Institute for Research in Ocular Surgery at 1 site in Austria.

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 6 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 18 Jan 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 Austria. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Johannes Zeilinger, MD (01 91021 ext. 57564, office@viros.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual acuity at intermediate distance (time frame: 24 months). 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 18 Jan 2022.
