Etymology: "Keratoplasties" is the plural of "keratoplasty," and the word is built from two Greek-derived parts. The first, "kerato-," comes from Greek "keras," meaning horn, and it appears in medical terms because the cornea, the transparent front layer of the eye, was compared to horn-like tissue in its toughness and clarity. The second, "-plasty," comes from Greek "plastos," meaning formed or molded, and it is the standard suffix for surgeries that reshape or rebuild a body part. Put together, a keratoplasty is literally a reshaping or rebuilding of the cornea. The plural simply counts multiple such operations. Like many medical terms of this kind, it was assembled from classical roots in modern medical language rather than used by ancient Greek physicians, who had no such surgical procedure.
