The claims of refractive surgeons especially the commercial ones like Lasik Plus are really just marketing claims and rarely does an eye see better after refractive surgery than it did before surgery with glasses or contact lens. If an adult eye say older than 16 have amblyopia and the eye has never seen better than 20/40 with glasses or contact it will only see 20/40 after refractive surgery at best. There are some exceptions. Early child refractive surgery can help and eye see better than with glasses. The first childhood refractive surgery unit in the United States and one of the few in the world is set up at Children's Mercy Hospital here in Kansas City, MO, USA under the direction of Erin Stahl, MD.
