—Our patient was first diagnosed as having keratoconus in 1962. This had advanced to keratoglobus by 1973. Following his right corneal transplant, the patient achieved 6/12 (20/40) visual acuity. Because of problems associated with a high-post keratoplasty astigmatism, central graft edema developed while the patient was wearing his contact lenses. At no time did the patient have evidence of diffuse epithelial pathologic characteristics. In our experience, this would be an example of a patient who would benefit from a relaxing corneal incision. One of us (P.S.B.) has performed 15 such procedures without any substantial effect on the anterior ocular surface.The surgeon in our case report (not one of the authors) was experienced in radial keratotomy at the time he performed the operation. Dr Thornton has stated that the use of a 2.5-mm optical zone is guaranteed to produce glare, flare, and halos. When this procedure was performed
