Driven by a belief that the world's poorest people deserve safe, affordable and high-quality eye care just as much as anyone else, Ruit has made it his mission to root out avoidable blindness. In 1994, he joined the late Australian eye doctor Fred Hollows, who was his mentor and close friend, in establishing Tilganga Institute of Ophthalmology — an eye hospital in Kathmandu devoted to providing world-class eyecare for the people of Nepal.The hospital makes the state-of-the-art lens that is commonly used in treating cataracts or myopia, and exports it to more than 30 countries worldwide. For the patients who cannot reach urban areas, Ruit and his team conduct mobile eye camps in remote parts of Nepal and neighboring countries.They often trek for days to those areas and clean out structures like tents, classrooms or even stables for use as temporary operating rooms.When the eyepatches (眼罩) come off the day after an operation, it's an extremely moving moment for all relevant persons.Ruit said that he was so grateful that he could make a difference in so many people's lives. 语篇解读：本文是一篇新闻报道。文章主要报道了尼泊尔医生Sanduk Ruit致力于发展中国家眼疾患者的眼科护理，他把根除可避免的盲症作为自己的使命。 1．What do we know about Ruit?

However, with the widespread use of gene editing come some moral issues and consequences.What if it is used improperly by those who seek fame and money? Most terribly, it is likely to create genetic viruses, weapons and so on. 本课结束 更多精彩内容请登录：www.zghkt.cn $
