Hyperopia

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 looked at how well contact lenses perform and how comfortable people find them. It included 36 adults who already wear soft contact lenses and have nearsightedness or farsightedness. Participants wore the lenses and had their vision tested after 10 hours.

This study compared two types of soft multifocal contact lenses (Proclear 1 Day and Clariti 1 Day) to see which one people liked better. 67 adults who already wore contact lenses and needed reading glasses tried both lenses and rated their overall satisfaction. The goal was to he…

This study compared two types of soft contact lenses to see which one people liked better for vision and comfort. 52 adults who wear contacts took part. They rated the lenses on a scale from 0 to 100. The goal was to find out if one lens performed better in everyday use.

This study tested two types of soft contact lenses—Myday Sphere and Myday Toric—in 32 people who already wear spherical lenses but have low astigmatism. Participants wore each lens type for one week and rated comfort on a 0-100 scale. The goal was to see if the toric lens offers …

This study tested new multifocal contact lenses designed for people with both presbyopia (age-related blurry near vision) and astigmatism (blurry vision due to an irregularly shaped cornea). 95 habitual contact lens wearers wore the lenses for 30 days, and researchers measured ho…

This study tested a special lens implant (EVO+ Visian ICL) in 47 adults to correct or reduce nearsightedness, farsightedness, astigmatism, and age-related reading problems (presbyopia). The lens was placed inside the eye to improve vision at all distances without removing the nat…

This study tested two different multifocal contact lenses in 106 people with presbyopia, an age-related condition that makes it hard to see up close. Participants wore each lens for a week to see how well they could see at different distances. The goal was to compare the performa…

This study tested whether a program of eye exercises could improve visual function and quality of life in 40 adults with refractive errors like nearsightedness, farsightedness, or astigmatism. Participants did 20-minute sessions three times a week for eight weeks, plus home exerc…

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 a device called IOLMASTER 700 TK to see if it can more accurately measure the eye's curvature in people who had laser vision correction and now need cataract surgery. Researchers compared four different lens calculation methods in 155 adults. The goal was to imp…

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.

This completed study tested a virtual eye model system (VEMoS) to help personalize cataract and refractive surgery. Researchers collected eye measurements from over 500 participants, including those having surgery and those with healthy eyes. The goal was to find which measuremen…
