This is an inability to focus on near objects which is normally due to the lens not being round enough. However in serious cases of hypermetropia distance vision is also affected.
The Excimer laser can correct the refractive error by removing the surrounding corneal tissue, creating a central bulge and a more round cornea.
This new form brings the point of light convergence further forward enabling it to focus on the retina giving a clear vision.
