A
Wouldn’t it be great if you could correct your eyesight, especially nearsightedness, and reduce your dependence on glasses and needn’t have eye surgery? The solution is called orthokeratology, or ortho-k (角膜塑形镜).
What is ortho-k?
Orthokeratology( ortho- k)is the fitting of specially designed contact lenses (隐形眼镜) that you wear overnight while you are asleep, the lenses gently reshape the front surface of your cornea (角膜) so you can see clearly the following day after you remove the lenses when you wake up.
How long does the ortho-k effect last?
You should be able to see acceptably well without glasses or contact lenses for a day or two, sometimes longer. For best results, one should wear the ortho- k lenses every might.
Who are good candidates for ortho-k?
Most people with mild to average nearsightedness are good candidates for ortho-k. Because the cornmeal reshaping effect is temporary, little risk is involved, and you can discontinue wearing the lenses at any time. Children and young adults who want to be gases-free but are too young for eye surgery or are afraid of taking the surgery often are good candidates for ortho-k. People who participate in contact sports or work in dusty environments that can have problems for contact lens wear also can be good candidates.
How much does ortho-k cost?
Costs also can vary based on the region of the country and the type of practice where you have the procedure performed. Ortho-k prices in the US generally range from $1, 000 to $2, 000 But particularly difficult cases of ortho-k can cost as much as $4.000.
There are additional costs for lens care solutions and following up exams, which can total about $300 to $ 500 per year.
Finally, keep in mind that, as with all contact lenses, there are some possible side effects of wearing ortho-k lenses. Ask your eye doctor for details.

【1题详解】
细节理解题。根据第一段“Wouldn’t it be great if you could correct your eyesight, especially nearsightedness, and reduce your dependence on glasses and needn’t have eye surgery? The solution is called orthokeratology, or ortho-k (角膜塑形镜). (如果你不需要做眼科手术就能矫正视力，特别是近视，减少对眼镜的依赖，那不是很好吗？这种解决方案被称为角膜塑形术，或角膜塑形镜)”以及第三段“Orthokeratology( ortho- k)is the fitting of specially designed contact lenses (隐形眼镜) that you wear overnight while you are asleep, the lenses gently reshape the front surface of your cornea (角膜) so you can see clearly the following day after you remove the lenses when you wake up. (角膜塑形镜是一种特殊设计的隐形眼镜，你在睡觉的时候戴上它，隐形眼镜轻轻地重塑你角膜的前表面，这样你在醒来的第二天摘下隐形眼镜后就能清晰地看到) ”可知角膜塑形镜是一种特殊设计的隐形眼镜，所以本文介绍了通过戴角膜塑形镜也就是特别设计的隐形眼镜，来纠正视力。故选D。
【2题详解】
细节理解题。根据Who are good candidates for ortho-k?介绍段落中“Most people with mild to average nearsightedness are good candidates for ortho-k. (大多数有轻度到中度近视的人都是角膜塑形镜的合适人选)”可知，角膜塑形镜对于中度近视的人来说是个不错的选择。故选B。
【3题详解】
细节理解题。根据倒数第三段中“Ortho-k prices in the US generally range from $1, 000 to $2, 000. (角膜塑形镜在美国的价格一般在1000美元到2000美元之间)”以及倒数第二段中“There are additional costs for lens care solutions and following up exams, which can total about $300 to $ 500 per year. (镜片护理解决方案和后续检查需要额外的费用，每年总计约300至500美元)”可知，使用角膜塑形镜第一年至少花费1, 000+300美元，也就是1, 300美元。故选B。
