About this study

The purpose of this multi-center, prospective, randomized, comparative clinical investigation was to evaluate and compare the visual performance at far, intermediate and near distances, the presence of photopic phenomena and patient satisfaction after cataract surgery in patients implanted binocularly with a Medicontur monofocal (877PAY) or a Medicontur extended depth of focus (877PEY) IOL models.

The visit schedule included a total of 6 visits, in addition to the IOL implantation surgery, with the listed follow-up timeline:

  • screening and baseline assessments
  • day 0 (IOL implantation surgery)
  • day 1
  • month 1
  • month 3
  • month 6
  • month 12
Being tested
VFQ- 25 (Visual Function Questionnaire), Optical Biometry, Slit lamps / Fundoscopy / Biomicroscopy, UDVA, CDVA

What participants receive

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

  • VFQ- 25 (Visual Function Questionnaire)Behavioural

    VFQ-25 questionnaire was used to evaluate patient satisfaction at the M3 and M12 visits.

  • Optical BiometryDiagnostic test

    Axial length, anterior chamber depth and corneal keratometric values K1-K2. All these parameters were measured at the screening visit and at the month 3 follow-up visit, using the ARGOS® Biometer or the ANTERION® Cataract App

  • Slit lamps / Fundoscopy / BiomicroscopyDiagnostic test

    The fundus and other ocular structures, such as the cornea, anterior chamber, iris, pupil, crystalline lens / IOL alignment, corpus ciliare and choroid were examined at screening visit, on the day of the surgery, and at the follow up visits D1, M1, M3, M6, and M12, using the slit lamp binocular indirect ophthalmoscopy.

  • UDVADiagnostic test

    Monocular and binocular Uncorrected Distance Visual Acuity (UDVA) was evaluated at all visits (preoperative, D1, M1, M3, M6 and M12), using the ETDRS chart.

  • CDVADiagnostic test

    Monocular and binocular Corrected Distance Visual Acuity (UDVA) was evaluated at all visits (preoperative, D1, M1, M3, M6 and M12), using the ETDRS chart.

  • UIVA / DCIVADiagnostic test

    Uncorrected and Distance Corrected Intermediate Visual acuity (UIVA / DCIVA) was evaluated postoperatively at M1, M3, M6 and M12, using an intermediate chart from 67 cm.

  • UNVA / DCNVADiagnostic test

    Uncorrected and Distance Corrected Near Visual acuity (UNVA / DCNVA) was evaluated postoperatively at M1, M3, M6 and M12, using a near chart from 40 cm.

  • Manifest RefractionDiagnostic test

    Manifest refraction was the monocular subjective refraction (Sph, Cyl, Axis) giving the best distance corrected visual acuity. It was measured at the screening visit and the follow-up visits Day 1, Month 1, Month 3, Month 6 and Month 12.

  • IOPDiagnostic test

    Intraocular pressure (IOP) was measured at all visits (preoperative, D1, M1, M3, M6 and M12), using a non-contact tonometer.

  • VADCDiagnostic test

    Visual Acuity Defocus Curve (VADC) was taken monocularly at M3, monocularly and binocularly at M6 and binocularly at M12, using the Multifocal Lens analyzer - MLA application.

  • CSDCDiagnostic test

    Contrast Sinsitivity Defocus Curve (CSDC) was taken under photopic conditions at M6 and M12, using the Multifocal Lens Analyzer - MLA application

  • CSV-1000Diagnostic test

    Contrast Sensitivity was measured using the CSV-1000 with distance correction in place at spatial frequencies of 3, 6, 12, and 18 cycles per degree (cpd). Measurements were taken under four different light conditions:

    • Photopic (M3 monocular and binocular, M6 binocular and M12 monocular)
    • Mesopic (M6 binocular)
    • Photopic with backlight (M6 binocular)
    • Mesopic with backlight (M6 binocular)
  • Tear film stabilityDiagnostic test

    Tear film stability was assessed at screening visit and at follow-up visits M1, M3, M6, and M12 using the non-invasive Tear break Up Time (TBUT) with fluorescein dye.

  • IOL implantationDevice

    The investigational device (877PEY) and the comparator (877PAY) intraocular lens models were implanted, using sutureless, small-incision phacoemulsification surgery.

Questions about this trial

What is this clinical trial studying?

An observational study of Cataract and Presbyopia, run by Medicontur Medical Engineering Ltd at 3 sites in Hungary.

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 8 inclusion and 25 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 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Hungary. 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?

DCIVA (time frame: measured at month 1, month 3, month 6 and month 12). 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 15 Oct 2024.
