title: 'Figure 8' ipsilateral autokeratoplasty. A modification using standard corneal trephines.
abstract: A modification of the "figure 8" ipsilateral autokeratoplasty uses a silicone wafer beneath a portion of a standard sized corneal trephine to limit its cutting edge. This procedure eliminates the necessity of a custom-made instrument in a seldom-performed operation.
