With both glasses and contact lenses, attempts have been made to reduce the impact on vision by correcting the astigmatism caused by the keratoconus itself; in more advanced stages, however, this type of correction is not possible.
In this case, the only possible treatment is surgery, which differs depending on the stage of the disease: it can be used intrastromal ring implantation, corneal transplantation, photoablation with an excimer laser, or cross-linking, a keratoconus treatment that strengthens the structure of the cornea by instilling eye drops containing riboflavin.
