This table is adapted from the 2019 Eye Banking Statistical Report8 using data from transplants performed in the United States. Percentages of transplant variants not indicated are marked with a dash. Percentages are rounded to the nearest hundredth percent. Keratoprostheses may be used for any indication, but frequencies are not reported.
ALK, anterior lamellar keratoplasty; EK, endothelial keratoplasty; PKP, penetrating keratoplasty.
