This study looks at whether giving free reading or distance glasses to older adults in rural areas can slow down memory and thinking problems. About 964 people aged 60-79 with poor eyesight but normal hearing and memory will take part. Half will get glasses, and the other half wi…

This study is checking the long-term safety of the IC-8 Apthera lens, which is implanted during cataract surgery. It focuses on a common complication called posterior capsule opacification (PCO), where the lens capsule becomes cloudy. Researchers will follow 435 people for 24 mon…

This study compares two types of trifocal toric lens implants used during cataract surgery to correct both cataracts and astigmatism. About 138 adults with cataracts and regular astigmatism will receive one of the two lenses. The main goal is to see which lens provides better int…

This study tests a machine learning model that predicts how much nearsightedness a person has without using dilating eye drops. The model uses standard eye measurements like autorefraction and corneal shape. If accurate, it could make eye exams quicker and more comfortable for ad…

Cataracts cloud the eye's lens and blur vision, and presbyopia makes it hard to focus up close after age 50. Researchers are testing an intraocular lens with a virtual aperture optic, implanted during cataract surgery, to see if it improves vision at distance, intermediate, and n…

This study tests a small device called the VisAbility™ Micro Insert System, which is placed in the eye to help people with presbyopia (age-related trouble seeing up close) read without glasses. It involves 33 adults aged 45 to 60 and will track safety and vision improvement over …

This study tests if a newer laser method (PRESBYOND laser blended vision) is better than standard monovision LASIK for treating presbyopia, which makes it hard to see up close as you age. About 100 adults aged 40 to 55 will be randomly assigned to one of the two surgeries. They w…

This study looks at whether people who already wear INFUSE One-Day multifocal contact lenses for presbyopia (age-related blurry near vision) feel more comfortable and see better after switching to DAILIES TOTAL1 multifocal lenses. About 30 satisfied lens wearers, aged 40 and olde…

This study tests a brief online program called Project Independence for caregivers of autistic youth aged 10 to 14. The program gives practical tools to help kids build daily living skills like dressing or chores. About 70 caregivers will be randomly assigned to the program or an…

This study tests whether Total30 multifocal toric contact lenses are more comfortable and provide better vision than current lenses for people with presbyopia (age-related blurry near vision). 32 adults aged 40 and older who already wear toric contacts will try the new lenses for…

This study compares two daily disposable multifocal contact lenses for people with presbyopia, an age-related condition that makes it hard to see up close. About 35 adults who already wear soft contact lenses will test each lens for one week. The goal is to see which lens provide…

This study looks at how people with presbyopia (age-related blurry near vision) feel about wearing multifocal contact lenses compared to regular contact lenses plus reading glasses. About 30 adults aged 40 and older will try both options and report which they prefer. The goal is …

Researchers at the University of Miami are studying whether advanced eye imaging devices can reveal useful information about the eye in health and disease. The study has two parts: one observes the eyes of healthy people and people with conditions such as multiple sclerosis, dry …

This study looks at how different types of artificial lighting affect how well people see after having presbyopia (age-related blurry near vision) corrected with special extended-depth-of-focus lens implants. Researchers will measure the minimum light needed for clear distance vi…
