ASTIGMATISM

This study is testing a two-part procedure to improve vision for people with astigmatism who are having cataract surgery. Doctors will make tiny laser cuts in the cornea and implant a special lens that can be adjusted with light after surgery. The goal is to see if this combinati…

This study is testing a new, custom-designed lens for cataract surgery in people whose corneas are irregularly shaped, which causes blurry vision that standard lenses can't fully fix. The goal is to see if this special lens can reduce the blurriness and improve vision more effect…

This study aims to compare a new type of LASIK eye surgery, called Ray-Tracing Guided LASIK, against three other established laser procedures for correcting nearsightedness and astigmatism. It will involve 120 participants, each having a different procedure in each eye to directl…

This study is observing how satisfied people are with their vision and quality of life after having LASIK eye surgery on both eyes. Researchers will follow 50 people with nearsightedness or astigmatism for up to 3 months after their procedure. They will measure how well people se…

This study aims to understand how comfortable daily disposable contact lenses feel for people with astigmatism during long days of wear. Researchers will recruit 40 current contact lens wearers to test the lenses and report their comfort levels. The main goal is to measure how ma…

This study measures how satisfied people are with their vision after LASIK eye surgery for nearsightedness and astigmatism. Researchers will follow 52 patients for 3 months after surgery, asking them about vision quality, symptoms like glare or halos, and overall satisfaction. Th…

This study is comparing two types of advanced lens implants used during cataract surgery. The lenses are designed to improve vision at near, intermediate, and far distances while also correcting astigmatism, with the goal of reducing dependence on glasses. Researchers will measur…

This study is testing how comfortable and clear the vision is with Total30 multifocal contact lenses during long days of wear. Researchers will follow 36 current contact lens wearers aged 40+ for one month, asking them to rate their comfort and vision quality at different times t…

This study aims to find out if one of two FDA-approved LASIK techniques works better for correcting nearsightedness and astigmatism. Up to 70 participants will have one eye treated with a standard 'wavefront-guided' method and the other eye with a newer 'ray tracing-guided' metho…
