Intraocular Lenses for Cataracts
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to compare different lens implants for cataract patients, focusing on vision and satisfaction. One group will receive different lenses in each eye, while another will receive the same lens in both eyes. The researchers aim to determine if different lenses provide similar or better vision, particularly in reducing visual disturbances like halos and glare. Individuals with age-related cataracts seeking treatment for both eyes might be suitable for this study. The lenses under study include Clareon PanOptix Pro and Clareon Vivity. As an unphased trial, this study offers participants the chance to contribute to valuable research that could enhance cataract treatment options.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that these intraocular lenses are safe for cataract patients?
Research has shown that the Clareon PanOptix Pro and Clareon Vivity lenses are generally well-tolerated by patients. For the Clareon PanOptix Pro, safety data from earlier studies showed good results with low risks of complications or serious side effects. Most patients achieved the desired vision correction with few problems.
Similarly, studies on the Clareon Vivity lens have shown it is safe for cataract patients. Some individuals might notice slight difficulty distinguishing different shades of the same color, but this lens still provides good overall vision. Both lenses are designed to improve vision after cataract surgery, focusing on reducing unwanted visual effects like halos or glare.
In summary, previous studies have demonstrated that both the Clareon PanOptix Pro and Clareon Vivity lenses are safe and effective, offering promising options for cataract patients seeking to improve their vision.12345Why are researchers excited about this trial?
Researchers are excited about Clareon PanOptix Pro and Clareon Vivity intraocular lenses for cataracts because they offer unique benefits not typically seen with standard monofocal lenses. Clareon PanOptix Pro is a trifocal lens designed to improve vision at near, intermediate, and far distances, potentially reducing the need for glasses after surgery. Meanwhile, Clareon Vivity uses non-diffractive technology to extend the range of vision, providing clearer vision in various lighting conditions without the halo and glare often associated with other multifocal lenses. These advancements could significantly enhance the quality of life for patients with cataracts by delivering a broader range of vision and greater visual comfort.
What evidence suggests that these intraocular lenses are effective for cataracts?
This trial will compare the effectiveness of different intraocular lenses for cataract surgery. Research has shown that the Clareon PanOptix Pro lens, which participants in one arm of this trial may receive bilaterally, is highly effective, with 87% of people achieving 20/20 vision after surgery. It efficiently uses light, enhancing clarity, and studies report less light scatter, reducing glare issues.
In contrast, the Clareon Vivity lens, which participants in another arm may receive in one eye, offers good vision at various distances, particularly improving vision for tasks like reading or using a computer. However, it may cause some loss in contrast sensitivity, making things appear less sharp, especially in dim lighting. Both lenses aim to improve vision after cataract surgery, each with its own strengths.13567Who Is on the Research Team?

Are You a Good Fit for This Trial?
Adults with bilateral age-related cataracts who are planning to have both eyes operated on for cataract removal. They should expect good vision post-surgery (20/25 or better) and have minimal astigmatism. People with corneal issues, macular disease, glaucoma, previous eye surgeries, amblyopia, severe dry eye, high levels of irregular vision surface (high HOA), a preference for monovision correction, active infections or inflammation in the eye area, or those who are pregnant cannot participate.Inclusion Criteria
