Clareon TruPlus Study
What this study is about
The purpose of this research study is to generate safety and performance data for Clareon TruPlus Monofocal Intraocular Lenses (IOLs). IOLs are medical devices that are implanted in the eye during cataract surgery to restore clear vision after the cloudy natural lens has been removed. IOLs are intended to remain in the eyes for the duration of the patient's lifetime.

The purpose of this research study is to generate safety and performance data for Clareon TruPlus Monofocal Intraocular Lenses (IOLs). IOLs are medical devices that are implanted in the eye during cataract surgery to restore clear vision after the cloudy natural lens has been removed. IOLs are intended to remain in the eyes for the duration of the patient's lifetime.
Interventions
DEVICE
Clareon TruPlus Monofocal Non-Toric IOL
Monofocal IOL implanted in the capsular bag in the eye for the visual correction of aphakia in adult patients. The Clareon TruPlus IOL is designed to maintain distance image quality while slightly extending the depth of focus compared to standard monofocal IOLs.
DEVICE
Clareon TruPlus Monofocal Toric IOL
Monofocal IOL implanted in the capsular bag in the eye for the visual correction of aphakia and pre-existing corneal astigmatism. The Clareon TruPlus IOL is designed to maintain distance image quality while slightly extending the depth of focus compared to standard monofocal IOLs.
PROCEDURE
Phacoemulsification
Minimally invasive surgery technique that utilizes ultrasonic vibrations to break up (emulsify) and remove a cloudy lens through a small, self-sealing, 2-3mm incision
Primary outcome measures
Mean Binocular Photopic Best Corrected Distance Visual Acuity (BCDVA)
Time frame: Day 0 preoperative, Month 1, Month 3, Month 12
Visual acuity (VA) will be assessed binocularly (both eyes together) with correction in place under photopic (well-lit) conditions at a distance of 4 meters. BCDVA will be measured using letter charts and recorded in logarithm of the Minimum Angle of Resolution (logMAR). The LogMAR VA scale ranges from -0.30 (20/10 Snellen) to 1.00 (20/200 Snellen). A LogMAR value of 0 equates to 20/20 Snellen VA (normal distance eyesight), with negative LogMAR values representing better than 20/20 VA. Subjects with at least one implanted eye with a toric IOL will be categorized as toric as specified in the statistical analysis plan. No hypothesis testing is pre-specified for this endpoint
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- Potential postoperative BCDVA of 0.2 logMAR or better in each eye in the expert medical opinion of the investigator.
- Astigmatism suitable for correction with available toric IOL models.
- Other protocol-specified inclusion criteria may apply. Key
Exclusion criteria
- Age-related macular degeneration (AMD), glaucoma, diabetic retinopathy, and other eye conditions as specified in the protocol.
- Moderate to severe dry eye that would affect study measurements.
- Other protocol-specified exclusion criteria may apply.
Where
- Phoenix, Arizona
- Brecksville, Ohio

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
