In 1936 I performed the first keratoplasty in a case of advanced keratoconus, with resulting pronounced improvement of vision and seemingly lasting cure. Encourage by the first trials, I proceeded to treat other patients with advanced keratoconus with corneal transplantation. The results have been most encouraging.
