About this study

Official title: Expanding Visual Horizons: Comparative Outcomes of a Novel Extended Depth-of-Focus IOL Versus Enhanced and Standard Monofocal IOLs

Consecutive comparative case series evaluating visual outcomes and patientreported satisfaction after bilateral cataract surgery with implantation of the same IOL type (standard monofocal, enhanced monofocal, or novel EDOF IOL). Outcomes assessed at 6 months included uncorrected visual acuity at distance, intermediate, and near; refraction; defocus curves; and questionnaires on halos, glare, and spectacle independence.

Read the detailed description

Patients undergoing bilateral phacoemulsification for age-related cataract received one of three IOLs in both eyes: Tecnis ZCB00 (monofocal), Tecnis Eyhance ICB00 (enhanced monofocal), or Asqelio EDOF ETLIO130C (EDOF). Follow-up examinations were performed at 1 day, 1 week, 1 month, 3 months, and 6 months. The 6-month assessment included monocular and binocular visual acuity at distance (6 m), intermediate (66 cm), and near (40 cm), manifest and objective refraction, binocular defocus curves (+1.00 D to -2.50 D in 0.50 D steps), and patient questionnaires (NEI-RQL-42 glare items; custom spectacle independence and satisfaction survey).

What is being measured

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

  1. Visual Outcomes

    • Binocular uncorrected distance visual acuity (UDVA) at 6 m, logMAR
    • Binocular uncorrected intermediate visual acuity (UIVA) at 66 cm, logMAR
    • Binocular uncorrected near visual acuity (UNVA) at 40 cm, logMAR

    Measured: 6 months

  2. Patient satisfaction score

    The patients were asked about their satisfaction with the refractive outcome, as used in International Multicenter Concerto Study as follows: How satisfied are you with your spectacle-free vision at far/intermediate/near distance? The answer choices ranged from 0 (not at all satisfied) to 10 (very satisfied).

    Measured: postoperative 6 months

Secondary outcomes (4)
  1. Visual acuity

    • Monocular UDVA, UIVA, UNVA (logMAR)
    • Monocular and binocular corrected visual acuity (CDVA, CIVA, CNVA) (logMAR)

    Measured: 6 months

  2. Objective refraction

    Manifest and objective refraction (spherical equivalent) (Diyoptri)

    Measured: 6 months

  3. Defocus curve

    Binocular defocus curve performance (+1.00 D to -2.50 D) (diyoptri)

    Measured: 6 months

  4. Photic phenomena

    Halo and glare scores (NEI-RQL-42 items 17 and 38; (0-100 scale)

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Age-related Cataract, run by Sakarya Yenikent State Hospital at 1 site in Turkey (Türkiye).

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 3 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 23 Apr 2026. 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 Turkey (Türkiye). 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?

Visual Outcomes (time frame: 6 months). The study lists 2 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 23 Apr 2026.
