Intraindividual Comparison of EMO IOLs (EMO)

November 27, 2025 updated by: Christina Leydolt, Medical University of Vienna

Comparison of Visual Outcomes of Enhanced Monofocal Intraocular Lenses

The investigational devices are approved intraocular lenses (IOLs) intended to be implanted after phacoemulsification in individuals suffering from age-related cataract with the need of cataract surgery. Cataract surgery with precedent bilateral randomized IOL implantation will be performed in subjects who have signed an informed consent form. Postoperative examinations will be implemented in accordance with the approved investigational plan.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
Distant corrected intermediate visual acuity
Time Frame: 2-6 months
Primary outcome measure will be monocular distant corrected intermediate visual acuity (DCIVA) of each intraocular lens implanted. DCIVA will be assessed using standardized early treatment diabetic retinopathy study (EDTRS) charts on a logarithm of the minimum angle of resolution (logMAR) scale.
2-6 months
Best-corrected distance visual acuity (BCDVA) - Acrysof IQ Vivity IOL, IC-8 Apthera IOL
Time Frame: 3-5 months
Primary outcome measure will be monocular best-corrected distance visual acuity (BCDVA) of each intraocular lens implanted in eyes with irregular astigmatism. BCDVA will be assessed using standardized early treatment diabetic retinopathy study (EDTRS) charts on a logarithm of the minimum angle of resolution (logMAR) scale.
3-5 months
Contrast sensitivity and reading ability - Vivinex XC1 and Vivinex XY1
Time Frame: 2-6 months and 1-5 years
Primary outcome measures for arm ten (X) will be the distance corrected contrast sensitivity and near corrected reading ability and reading speed. Contrast sensitivity will be assessed under standard photopic (85cd/m2) and mesopic (3cd/m2) conditions
2-6 months and 1-5 years

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
Contrast sensitivity and reading ability
Time Frame: 2-6 months and 1-5 years
Secondary outcome measures will be the distance corrected contrast sensitivity and near corrected reading ability and reading speed. Contrast sensitivity will be assessed under standard photopic (85cd/m2) and mesopic (3cd/m2) conditions.
2-6 months and 1-5 years

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.
December 13, 2021

Primary Completion (Estimated)

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 (Estimated)

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.

Study Registration Dates

First Submitted

First Submitted

The date on which the study sponsor or investigator first submitted a study record to ClinicalTrials.gov. There is typically a delay of a few days between the first submitted date and the record's availability on ClinicalTrials.gov (the first posted date).

First Submitted That Met QC Criteria

First Submitted That Met QC Criteria

The date on which the study sponsor or investigator first submits a study record that is consistent with National Library of Medicine (NLM) quality control (QC) review criteria. The sponsor or investigator may need to revise and submit a study record one or more times before NLM's QC review criteria are met. It is the responsibility of the sponsor or investigator to ensure that the study record is consistent with the NLM QC review criteria.
