  37. 37. Treatment Success<br />The success of any form of treatment depends on the progression of the disease<br />Corneal transplantation, although highly successful, is reserved for the more severe cases<br />The transplanted cornea, once fully healed, can give rise to vastly improved vision compared to pre-transplantation keratoconus vision<br />Many new techniques in transplantation and contact lens fitting make treating keratoconus much more manageable <br />
