CATARACT

This study tests a special lens implant that corrects cataracts, presbyopia (need for reading glasses), and astigmatism (blurry vision from an irregularly shaped cornea). The goal is to see if this lens stays stable in the eye and provides good vision at all distances. About 100 …

This study follows 61 adults with mild-to-moderate cataract who previously used the REVISYON SDS 100 device. Researchers will monitor side effects and vision changes over about 20 months to see if the device remains safe and effective. No new treatment is given; it is an observat…

This study tests a special implant placed in the eye during vitrectomy (a surgery to remove the eye's gel). The implant releases a drug to slow down cataract formation, which often happens after vitrectomy. About 30 adults who need vitrectomy and already have some cataract will t…

This study follows 23 people who received a special lens implant that slowly releases glaucoma medication during cataract surgery. Researchers want to see if the implant keeps eye pressure low and vision clear for up to 7 years. Participants already completed an earlier study and…

This study compares a new trifocal lens (D615L) to a standard lens (Zeiss 839MP) for people having cataract surgery. The goal is to see if the new lens provides better vision at all distances without glasses. 90 adults with age-related cataracts will receive one of the two lenses…

This study tests a new type of lens that uses fluid to help focus, compared to a standard fixed-focus lens, in 175 people having cataract surgery. The goal is to see if the new lens improves vision and causes fewer side effects. Participants must have cataracts in both eyes and b…

This study tests a new type of artificial lens (Clareon TruPlus) for people having cataract surgery in both eyes. The goal is to see if this lens gives better vision at arm's length (about 66 cm) while still keeping distance vision clear. Fifty adults with age-related cataracts w…

This study looks at whether playing music for people before cataract surgery can lower their anxiety, reduce pain after the operation, and make them more satisfied with the procedure. About 60 adults having cataract surgery will take part. Researchers will measure anxiety using s…

This study looks at 346 cataract patients who will receive either a mix of two different artificial lenses (one in each eye) or the same lens in both eyes. The goal is to see which approach gives better vision and fewer visual disturbances like glare and halos. Participants will …

This study tests a new type of lens (enVista Beyond) placed in the eye during cataract surgery. The goal is to see if it helps people see clearly at far, middle, and near distances without needing glasses. About 304 adults with cataracts are taking part to check the lens's safety…

This study looks at 50 adults having cataract surgery to see if using numbing eye drops (topical anesthesia) or full sleep (general anesthesia) leads to less pain after the operation. Researchers will check pain levels, side effects, and how satisfied patients are at 24 hours, on…

This study aimed to compare two newer technologies for cataract surgery—a femtosecond laser and a special handpiece that monitors eye pressure—against standard surgery. The goal was to see which approach causes less damage to the eye's inner lining and uses less energy. However, …

This study looks at how well artificial lenses implanted during cataract surgery help people see. Researchers will measure vision and patient satisfaction 3 to 6 months after surgery. The goal is to understand what makes some lenses work better than others, so future designs can …

This study follows about 110 people who were in the original AREDS or AREDS2 studies for an additional 5 years. The goal is to observe how age-related macular degeneration and cataracts naturally progress over time. Participants get a yearly eye exam and a check-in phone call. No…

This study uses a special scanning device to measure how stiff the lens of the eye becomes with cataracts. Researchers will compare these measurements with standard cataract grading and surgery energy needed. The goal is to better understand cataract properties, which could help …

This pilot study looks at 40 adults with type 2 diabetes and age-related cataracts who take metformin. Researchers measure how much metformin reaches the lens capsule and test whether it slows lens cell growth in the lab. The goal is to understand if metformin might help prevent …

This study offers free vision screenings to underserved adults over 40 living in affordable housing in Harlem and Washington Heights. The goal is to find eye problems like glaucoma, cataracts, and diabetic retinopathy early and connect people with follow-up care. About 749 partic…

This study was designed to observe how doctors treat cataracts in children, looking at different surgery methods and implants. It planned to include children aged 0 to 17 having cataract surgery at a specific hospital. However, the study was withdrawn before any participants were…

This study aimed to compare two different surgical systems for cataract removal in adults with moderate to severe cataracts. It planned to enroll people needing surgery in both eyes and track energy use during the procedure. However, the study was withdrawn before any participant…
