To look someone in the eye 双眼直视某人

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 cornea 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组织。刚刚死亡的人的健康角膜可以通过手术被移植到另一个眼球上去替换伤损或患病的角膜。世界上首例角膜移植手术是由爱德华▪则姆完成的。这例手术也成为了早期移植手术的成功典范之一。
