Hyperopia

This trial tests whether implanting a fresh, donated corneal lenticule — a thin layer of corneal tissue — can safely correct residual farsightedness in people who already have an artificial lens implant after cataract surgery. The procedure uses a femtosecond laser to create a po…

This trial tests whether implanting a fresh corneal lenticule — a thin layer of donor cornea — can improve vision in people with high hyperopia (farsightedness) and high astigmatism. The lenticule is placed using a femtosecond laser, aiming to increase visual acuity and reduce as…

This trial tests whether a laser procedure called Relex-Smile can correct leftover nearsightedness or farsightedness in people who had cataract surgery six months earlier. About 130 participants with blurry vision after receiving a trifocal lens implant will undergo the laser tre…

This study compares a new AI system, called AEYE, against a human eye doctor in diagnosing keratoconus and deciding who is eligible for laser vision correction. The AI analyzes patient history, eye scans, and other data to make its recommendations. Researchers will check if the A…

This study tests whether special 'peripheral focus-out' glasses can prevent nearsightedness (myopia) in Chinese children aged 6 to 8. Over two years, 160 children will wear the glasses at least 8 hours a day. Researchers will measure changes in their vision to see if the glasses …

This study tests the safety and effectiveness of the TENEO 317 excimer laser used in LASIK surgery to treat farsightedness (hyperopia) with or without astigmatism. About 140 adults aged 22 and older will receive the laser treatment in one or both eyes and be followed for 12 month…

This study uses artificial intelligence to predict true eye pressure after corneal refractive surgery like LASIK or SMILE. Standard eye pressure measurements can be falsely low after these surgeries, masking glaucoma risk. Researchers will analyze data from over 10,000 participan…
