This trial compares two daily disposable multifocal contact lenses to see which provides better vision at near, intermediate, and far distances, and which is safer for the eyes. About 150 adults aged 40 to 70 who need multifocal lenses will wear each type and have their vision te…

This early study tests a special contact lens that has a tiny pinhole built in. The idea is that the pinhole helps focus light better, improving vision for people with presbyopia (age-related blurry near vision) or keratoconus (a cone-shaped cornea). Sixteen adults will try the l…

This study will test a new fitting experience for multifocal contact lenses in 25 people with presbyopia (age-related blurry near vision). Participants, who already wear certain contact lenses, will use an at-home trial kit with the new lens for 15 minutes daily. The goal is to s…

This early-stage trial tests a non-invasive device that uses controlled UV light to reshape the cornea, potentially reducing the need for reading glasses in people with presbyopia. The study will enroll 25 adults aged 40 to 65 with healthy corneas. The main goal is to see if the …

This study follows adults having cataract surgery who choose either a trifocal or monofocal intraocular lens implant. It asks whether one type leads to more difficulty or visual disturbances, like glare or halos, when driving at night. Participants must be licensed drivers with r…
