A doctor recently diagnosed me with keratoconus. It is very often hereditary.
Contact lenses are the treatment of choice for keratoconus.
I believe you are referring to the SoftPerm lens manufactured and sold by the Wesley Jessen company. This lens is a very good choice to help people with keratoconus. When keratoconus becomes untreatable with contact lenses, the next step is to have a corneal transplant, where the center of the cornea is removed and a donor cornea is put in its place. I have heard these are called floaters. He does work on computers almost all hours of the day, but today he had great trouble seeing out of his right eye.
