LBV vs traditional monovision LASIK for presbyopia
In adults 40–55 with presbyopia, this study tests whether laser blended vision (LBV) provides better vision at distance, intermediate, and near after LASIK than traditional monovision LASIK.
-
A.M.L. spectacle lenses for children with myopia
We will try A.M.L. spectacle lenses in 6- to 12-year-old children with myopia to see how quickly they adapt and how comfortable the lenses feel.
-
Choroidal thickness change after 1 hour wearing prototype soft contact lenses
This test will see if three prototype soft contact lenses change choroidal thickness in people aged 18 to 25 with myopia.
-
Optimizing SMILE surgery for correcting vision problems
This study is testing if using a new system for SMILE eye surgery can help patients see better after the procedure compared to the traditional method.
-
Evaluating a device for screening vision problems in young children
This study is testing a new device to see if it can effectively find vision problems in children aged 3 to 8, whether they wear glasses or not.
-
Optimizing light exposure to prevent and control myopia in children
This study tests if changing classroom lighting to mimic sunlight or using a smartphone app to guide light exposure can help prevent and control myopia in primary school children.
