Keratoconus is a condition where the cornea develops progressive thinning. This can be treated in a number of ways. One of the treatments, which is approved in this country, is the use of intacts rings to stabilize the cornea from progression early in the disease process. The intacts rings can then be removed later in life when the patient may require a PKP. Penetrating Keratoplasty is the mainstay of therapy in this country with progressive thinning of the cornea. This is a through and through dissection of the tissue. The following procedure not available in this country at this time is cross-linking, which when available, will help the progression of Keratoconus in the early stages.
