EDOF vs Enhanced vs Monofocal IOLs After Bilateral Cataract Surgery

April 21, 2026 updated by: Ali Altan Ertan Boz, Sakarya Yenikent State Hospital

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Visual Outcomes
Time Frame: 6 months
  • 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
6 months
Patient satisfaction score
Time Frame: postoperative 6 months
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).
postoperative 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Visual acuity
Time Frame: 6 months
  • Monocular UDVA, UIVA, UNVA (logMAR)
  • Monocular and binocular corrected visual acuity (CDVA, CIVA, CNVA) (logMAR)
6 months
Objective refraction
Time Frame: 6 months
Manifest and objective refraction (spherical equivalent) (Diyoptri)

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 5, 2022

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
