While scleral lenses aren’t a cure for keratoconus, they are highly effective at correcting vision if you have irregular-shaped corneas or cone-shaped corneas.
Because those with keratoconus have irregular, cone-shaped corneas, glasses and standard contact lenses cannot conform to the shape of the eyes and thus cannot adequately correct the patients’ vision. The best solution, therefore, is scleral contact lenses, since they sit on the sclera without touching the cornea and deliver maximal clarity while being perfectly comfortable in most cases.
