In summary, these finding show us several things. First, we know that with surgery keratoconus patients can be rehabilitated to achieve excellent vision. A postoperative average visual acuity of 20/20 after an average preoperative visual acuity of 20/500 is a most positive outcome. Secondly, the average amount of postoperative astigmatism of 3.5 diopters shows that even after totally removing a corneal button and replacing it with 360 degrees of sutures we can still achieve a relatively small amount of residual astigmatism and a relatively spherical cornea. Thirdly, with the exception of one primary donor failure, a total of one hundred percent clear grafts, even after the occurrence of two graft rejection episodes, indicated an extremely high success rate of keratoplasty in keratoconus.
