A 19-year-old woman sustained a corneal laceration in her right eye. After bacterial keratitis was treated by antibiotics and a conjunctival flap, she developed a corneoscleral ectasia. We used a 15-mm diameter scleral ring as a template for corneoscleral graft. We obtained uniform donor and host buttons by suturing the ring alternately to donor and host eyes. One year postoperatively, the patient had a retrograft fibrous membrane with corneal edema, a visual acuity of R.E.: 6/60 (20/200), and intraocular pressure of 16 mm Hg.
