The authors report preliminary findings in 34 patients treated with oversize donor buttons for keratoconus. Seventeen patients received oversize donor grafts and 17 received same-size material. A significant increase in myopia was observed in the oversize group when compared with the same-size group, which indicates a trend toward increased corneal curvature in oversized corneal grafts. Oversize material therefore is contraindicated in treating keratoconus.
