Symfony vs Vivity in Dim Light

January 24, 2025 updated by: Carolina Eyecare Physicians, LLC

Evaluation of the Symfony With Optiblue Intraocular Lens Compared to The Vivity IOL Under Mesopic Conditions

The purpose of this study is to evaluate the visual outcomes of the Symfony lens and the Vivity lens under mesopic lighting conditions in adult patients undergoing routine cataract surgery. Participants will be asked to read a visual acuity chart at different distances in dim light.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Subject is undergoing bilateral lens extraction with implantation of an EDOF IOL with a target refraction of plano OU.
  2. Gender: Males and Females.
  3. Age: 50 years and older.
  4. Willing and able to provide written informed consent for participation in the study
  5. Willing and able to comply with scheduled visits and other study procedures.
  6. Scheduled to undergo standard cataract surgery in both eyes, with 1 to 30 days between surgeries.
  7. Potential postoperative visual acuity of 0.2 logMAR (20/32 Snellen) or better in both eyes.

Exclusion Criteria:

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
Binocular Distance Corrected Intermediate Visual Acuity at 66 cm Under Mesopic Conditions.
Time Frame: 3 months after surgery
logMAR visual acuity
3 months after surgery

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
Binocular Distance Corrected Intermediate Visual Acuity at 40 cm Under Mesopic Conditions.
Time Frame: 3 months after surgery
3 months after surgery
Binocular Low Contrast Distance Visual Acuity Under Mesopic Conditions
