In cases of keratoconus and consequent penetrating keratoplasty, the refractive requirements of the patient determine the dimensions of the donor button and the receiving wound size. The pre-operative biometric evaluation of the axial parameters may induce the surgeon to choose an oversized button to obtain the right curvature of the cornea and avoid hypermetropia. In this study we present 20 patients transplanted between 1993 and 1995, 13 female, 7 male, aged between 23 and 45 years. These cases demonstrate the utility of this easy and economic technique.
