The cornea is the transparent front part of the eye. Corneas can be transplanted by an operation where a damaged or diseased cornea is replaced with one from someone who has just died. The first corneal transplant was in 1905 by Eduard Zirm. It was one of the first successful transplant operations.

角膜是眼球最前面的一片透明組織。剛剛死亡的人的健康角膜可以通過手術被移植到另一個眼球上去替換傷損或患病的角膜。世界上首例角膜移植手術是由愛德華?則姆完成的。這例手術也成為了早期移植手術的成功典范之一。
