Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Detailed Description

In this study, subjects with cataracts in both eyes will undergo cataract surgery and be implanted with trifocal IOLs. One eye will receive the investigational IOL Model LPYWT0 IOL, and the other eye will receive the commercially marketed Clareon PanOptix Pro IOL Model PXYWT0. The second eye surgery will occur 7-14 days after the first. Subjects will attend 9 planned study visits to include for an individual duration of participation of approximately 7 months.

This study is planned to be conducted in India and the Philippines.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

Key Inclusion Criteria:

  • The calculated power needed for the artificial lens (IOL) must be between +15.0 and +25.0 D in each eye, designed to bring subject vision as close to "0.0" (neutral) as possible, meaning they will not be strongly nearsighted or farsighted after surgery.
  • Subjects must have low levels of astigmatism (misshapen cornea) in the eyes (less than 1.00 D).
  • In the doctor's opinion, the subjects have the potential to achieve good vision (0.2 logMAR, which is roughly 20/32 Snellen or better) in each eye after the surgery, when wearing the best possible spectacles or contact lenses.
  • Other protocol-specified inclusion criteria may apply.

Key Exclusion Criteria:

  • Clinically significant corneal diseases which may, according to the investigator's medical opinion, adversely affect visual outcomes.
  • Any ocular or systemic health condition or medical issue that, in the investigator's medical opinion, could make the study results unreliable, prevent the person from finishing the study, or increase their safety risk.
  • People who want to have one eye set for distance vision and the other for near vision.
  • The doctor expects significant blurry vision (astigmatism) after the procedure.
  • Other protocol-specified exclusion criteria may apply.

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
Mean Monocular Photopic Best Corrected Distance Visual Acuity (BCDVA)
Time Frame: Month 6 postoperative
Visual Acuity will be assessed using letter charts under well-lit (photopic) conditions with correction in place at a distance of 4 meters from the subject. BCDVA will be recorded in logarithm minimum angle of resolution (logMAR) where 0.0 logMAR is equivalent to 20/20 Snellen, or normal distance eyesight, and negative logMAR values represent better-than-normal distance eyesight.
Month 6 postoperative
