3、Each cluster includes a pair of eyes with a sophisticated lens, retina, iris andcornea. Scientists aren't sure how they process what they see.(每组包括一对拥有复杂晶状体、视网膜、虹膜和角膜的眼睛。科学家们还不确定它们如何处理它们看到的东西。)

5、Stromal haze with opacification of thecornea is a common finding (shown).(角膜基质浑浊且透明性丧失是一项常见体征(如图所示)。)
6、Among the organs most commonly transplanted are the heart, kidneys, lungs, livers, pancreas, small bowel andcornea.(在所有器官中，最常受到移植的是心脏、肾脏、肺、肝脏、胰腺脏、小肠和角膜。)
7、LASIK is performed using a laser programmed to remove a defined amount of tissue from yourcornea.(LASIK眼科手术是用激光程序从你的角膜移除预定数量的组织。)
8、This clouding can be caused by an inflammation under the flap ofcornea tissue.(这种浑浊是由角膜瓣下角膜组织的炎症反应所造成的。)
9、Infection of thecornea (keratitis).(角膜感染(角膜炎)。)
10、We produce tears in response to insults to the eyes—the sting of onion fumes, a tiny insect that flew into yourcornea.(当眼里受到攻击时，我们以泪水应对，比如洋葱气味的侵袭，小虫飞进了眼睛。)
11、Thecornea is the eye's clear outer surface that provides most of the visual power.(角膜是眼球外侧一层透明的膜，在视觉系统中非常重要。)
12、The aim is to report the effect of treating phlyctenular keratopathy with intralamellar cauterization ofcornea.(目的是报告用角膜层间烧灼术治疗大泡性角膜病变的疗效。)
13、They are not considered a major hazard outside the human body, although in large doses, they can damage thecornea of the eye.(尽管大量的β粒子会造成眼角膜损害，但人们并不将其视为人体外的主要危害。)
14、Have a disease or abnormality of thecornea, such as keratoconus orcorneal edema.(角膜有异常或病变，比如圆锥角膜或角膜水肿。)
15、If left alone, they eventually can grow large enough to cover thecornea and impair sight.(如果不加治疗，它们最终会增大到足以覆盖角膜从而损伤视力。)
16、Ozzy and Drix set up a detective firm behind Hector'scornea — they're "private eyes" — to ensure him a safe adolescence.(奥兹和德里克斯在赫克托尔的角膜后面成立了一家侦探事务所---他们是“私人的眼睛”---为的是确保他安全度过青春期。)
17、The objective was to assess the relationship betweencornea arcus senilis and blood fat & arteriosclerosis.(目的是探讨角膜老年环与血脂及动脉硬化的关系。)
18、Astigmatism: distorted vision resulting from an irregularly curvedcornea, the clear covering of the eyeball.(散光：因角膜(覆盖眼球的一层透明膜)不规则弯曲而引起的影象变形。)
19、The laser allows your eye surgeon to flatten the curve of yourcornea or make it steeper.(眼科医生用激光把角膜变平或者变陡。)
20、The laser removes tissue from thecornea very accurately without damaging nearby tissues.(激光可以非常精确地切削角膜组织且不损伤邻近组织。)
21、Doctors have long known that amantadine treatment causes abnormal changes in thecornea in some Parkinson's patients.(医生们早就知道金刚烷胺在一些帕金森病人身上能够导致角膜功能异常。)
22、The lesions were found in the conjunctiva, episclera,cornea, iris, lens, vitreous, and retina.(病变见于结膜，上巩膜，角膜，虹膜，晶状体，玻璃体和视网膜。)
23、LASIK eye surgery changes the shape of yourcornea—the transparent membrane that arcs over your pupil and the colored part of your eye (iris).(LASIK眼科手术改变了你的角膜的形状——角膜是覆盖在你的瞳孔和你的眼睛的有色部分（虹膜）上的弧形透明膜。)
24、These lenses cover not only thecornea, like a regular contact, but also the surrounding area.(该隐形眼镜不仅覆盖普通隐形眼镜也覆盖的角膜，而且还覆盖角膜周围组织。)
25、For those who wear contacts which are too tight, the risks include swelling of thecornea, redness orcorneal abrasion.(如果佩戴过紧的隐形眼镜，那么可能会导致使用者角膜肿胀、眼部泛红或是角膜损伤。)
