中国科学家研发新型隐形眼镜，可实时监测眼压辅助治疗青光眼
Contact lens that can release drug could be used to treat glaucoma

A contact lens that can release a drug if it detects high pressure within the eye has been created by scientists who say it could help treat glaucoma.科学家发明了一种隐形眼镜，当它检测到眼压升高时，就会释放药物。科学家宣称这种隐性眼镜可辅助治疗青光眼。

According to the charity Glaucoma UK, the most common form of the disease, known as primary open angle glaucoma, is thought to affect almost 10% of people older than 75. This form is generally caused by increased pressure within the eye, usually as a result of a buildup of fluid.据英国青光眼慈善机构称，原发性开角型青光眼是最常见的一种青光眼疾病，近10%的75岁以上人群患有该眼病。原发性开角型青光眼通常是由眼内压力增加引起的。眼压升高通常是由液体积聚造成的。

Writing in the journal Nature Communications, the team describe how they created the device using an upper and lower lens, with a snowflake-shaped pressure sensor and wireless power transfer device sandwiched between them around the rim of the lenses. 该团队在《自然通讯》杂志上发表文章，描述了他们如何利用上下两块镜片创造出这个设备的，在两块镜片之间的边缘夹着雪花状压力传感器和无线电力传输装置。

The study reveals that the contact lenses have so far been tested on pigs’ eyes and on the eyes of living rabbits – albeit with smaller-sized lenses – although trials have yet to be carried out in humans.这项研究表明，尽管隐形眼镜的尺寸较小，但目前为止已经在猪的眼睛和活兔子的眼睛上进行了测试，尚未进行人体试验。

Prof Zubair Ahmed from the Institute of Inflammation and Ageing at the University of Birmingham, who was not involved in the work, said the research was potentially very exciting, adding that a rise in pressure within the eye was a significant problem for most people with glaucoma.伯明翰大学炎症与衰老研究所的祖拜尔·阿赫默德教授没有参与这项研究，他称这项研究成果激动人心，眼压升高对大多数青光眼患者来说是一个严重问题。
