What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new device called the Optimal Acuity Clear-K® Low Vision Aid System to determine if it can safely and effectively improve vision for people with age-related macular degeneration (AMD), which causes blurry or reduced vision. It targets patients diagnosed with either dry or inactive wet AMD in one or both eyes. Participants should have moderate to severe vision impairment and not wear contact lenses. Those who struggle with clear vision due to AMD and do not have other eye conditions like cataracts might be suitable for this trial. As an unphased trial, this study provides a unique opportunity to explore innovative solutions for vision improvement in AMD patients.

Do I need to stop 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 coordinator or your doctor.

What prior data suggests that the Optimal Acuity Clear-K® Low Vision Aid System is safe for patients with age-related macular degeneration?

Research shows that the Optimal Acuity Clear-K® Low Vision Aid System is being tested for safety and effectiveness in people with age-related macular degeneration. Earlier studies suggest that similar treatments, such as corneal laser procedures, are generally safe. These treatments can enhance vision by making small changes to the cornea (the clear front part of the eye) and redirecting light to healthier parts of the retina (the light-sensitive layer at the back of the eye). Although data is limited, these treatments are usually well-tolerated, with few serious side effects reported. This suggests that the Clear-K system may also be safe, but ongoing studies are needed to confirm this. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard treatments for age-related macular degeneration (AMD), which typically involve medications like anti-VEGF injections to slow vision loss, the Optimal Acuity Clear-K® Low Vision Aid System offers a new approach by enhancing residual vision. This system is unique because it uses advanced optics and digital processing to improve visual clarity and contrast for people with AMD. Researchers are excited about this treatment because it could significantly improve the quality of life for patients by making everyday activities easier, offering a non-invasive alternative to traditional therapies.

What evidence suggests that the Optimal Acuity Clear-K® Low Vision Aid System is effective for age-related macular degeneration?

Research has shown that the Optimal Acuity Clear-K® Low Vision Aid System might help people with age-related macular degeneration see better. This system reshapes the cornea slightly to direct light onto functioning parts of the retina, potentially improving vision. Early results suggest that users of this system have experienced clearer vision. However, researchers are still collecting more detailed study results to confirm its effectiveness. ^{1 2 3 4 6}
