For some time ophthalmologists have recognized that keratoplasty corrects keratoconus in a large percentage of cases. There is, however, some difference of opinion as to the optimal size of the grafts. Castroviejo1 and others have suggested a large graft which replaces the entire conus, because the high corneal curvature remaining after a smaller graft may cause a high enough degree of astigmatism and myopia to interfere seriously with vision. Paton2 and others, however, have found that, while a larger graft may at times be desirable, in most instances the visual problems following a small graft are not severe enough to warrant risking the complications which are frequently associated with large grafts. The purpose of the present study is to evaluate the vision and refraction errors following 6 and 7 mm. corneal grafts for keratoconus.
