There are several methods for treating keratoconus, depending on how serious the condition is. In the early stages of the disease, vision can be corrected with regular glasses or soft contact lenses.
As the keratoconus deteriorates, vision may no longer be able to be corrected with glasses due to irregular astigmatism, and so the patient may need to place a special type of hard contact lens.
For some patients, the disease can proceed to a stage at which they do not have acceptable vision even with glasses or contact lenses. At this point, the doctor may recommend a corneal transplant, which is a surgical procedure to replace the cornea with a cornea by a donor.
