Transient refractive change

This study tested a special laser (femtosecond laser) to adjust an artificial lens already placed inside the eye after cataract surgery. The goal was to correct leftover blurriness or astigmatism so people need glasses less. Twelve adults with at least one diopter of remaining re…

This study tested a new prototype device that uses light field technology to measure vision problems like nearsightedness and farsightedness. Researchers compared its accuracy to standard methods in 120 healthy adults. The goal was to see if this new approach could reliably deter…

This study checked if a smartphone app called VisionApp can accurately measure vision problems like nearsightedness and presbyopia (age-related reading difficulty). Sixteen adults aged 40 and older used the app at home, and their results were compared to standard eye exams. The g…

This study tested how well a new device (ELITA) docks onto the eye for refractive error treatment. 55 adults participated to see if the docking procedure works correctly. The study did not provide treatment, only measured the device's performance.
