白内障是眼睛镜头的变色，导致其透明度的丧失导致视觉干扰。发生白内障的机会随着年龄的增长而增加。大多数65岁以上的人都可以至少一只眼睛有白内障。白内障发育的其他因素包括遗传学，营养不良，糖尿病，感染或眼睛创伤。识别白内障的早期症状对于预防严重视力问题至关重要。

专家估计，与白内障相关的视觉障碍占美国每年的医师办公室访问超过800万。随着60岁以上人群的比例，这个数字可能会继续增加。当人们发展白内障时，他们开始难以进行日常生活或享受所需的活动。一些最常见的抱怨包括在夜间驾驶，阅读，参加活动或前往陌生地区的困难；清晰视力至关重要的所有活动。

Cataract Causes
镜头大部分都是由水和蛋白质。规范ific proteins within the lens are responsible for maintaining its clarity. Over many years, the structures of these lens proteins are altered, ultimately leading to a gradual clouding of the lens. Over time, glasses and contacts may no longer work as well to help you see clearly. Contacting an ophthalmologist should always be the first step after noticing any vision changes or impairments. A thorough eye exam can determine the problem and what vision correction surgeries are recommended. Cataract surgery is one of the most frequently performed, safest and most successful surgeries in the United States that is covered by insurance.

Many people don’t even recognize the early signs of cataracts, they just know they do not see as good anymore. Some patients begin having early cataract symptoms as early as 40. However, cataracts may also develop in those much younger than 40. Most insurance plans pay for cataract surgery procedures using standard lenses, subject to deductibles and co-pays.

眼内镜头或智能镜头（例如Restor®或Crystalens®）在眼睛中更换旧镜头。超声能量用于去除白内障。在用人造镜头代替之前，使用称为Phaco探针的仪器去除天然镜头。这些优质镜头几乎可以消除戴眼镜的需求，无论是阅读还是远见。

白内障手术是门诊手术，只需几分钟即可进行。先进的技术已经发展起来，并且每年越来越多地执行。大多数人注意到手术后的视力有所改善。人们在手术后的第二天恢复正常活动。实际上，使用新技术，您对眼镜的依赖可以大大减少或几乎消除。
