Cataracts to be Treated Very Carefully白內障的治療要非常小心
What are cataracts, and how are they diagnosed and treated, especially non-surgically? 什麼是白內障，及他們如何診斷和治療，特別是非手術？
A cataract is a clouding of the lens of the eye.白內障不是一層的眼球晶狀體對。 To fully understand cataracts, it is important to understand the eye's anatomy.要充分認識白內障，這是重要的是要了解眼的解剖。
The eye has several major structures: The outermost structure is the cornea, which is like the crystal on a watch.眼睛有幾個主要的結構：最外層結構是角膜，這是一樣的晶體就一隻手錶。 It is clear and protects the inner structures of the eye.它是明確和保護的內在結構的眼睛。
The iris, which is behind the cornea, is the colored part of the eye, and it regulates the amount of light getting into the eye.虹膜，這是背後的眼角膜，是彩色的一部分，眼睛，和規管的光量進入眼睛。 Just behind the iris is the lens.僅落後於虹膜是鏡頭。 This is like the lens on a camera, helping to focus the light entering the eye onto the retina.這是像透鏡對照相機，幫助把重點放在輕進入眼睛的視網膜上。
The retina lines the inside of the eye like film in a camera.視網膜線內的眼睛一樣，電影在一個攝像頭。
For a person to see well, all of these structures must be healthy.一個人看到，所有這些結構必須健康。
Symptoms : 症狀：
The symptoms of cataracts include blurry vision, difficulty seeing well enough to read and drive, seeing a great deal of glare and halos.症狀包括白內障模模糊糊的視野，看到困難，以及足夠的閱讀和幹勁，看到了大量的眩光和光環。
An ophthalmologist can diagnose cataracts during an eye examination.眼科醫生可以診斷白內障在眼睛健康檢查。
Factors that increase a person's risk for developing cataracts include : 因素，增加一個人的風險，為發展中國家的白內障，包括：
Age, a family history, smoking, diabetes mellitus, injury to the eye, chronic steroid use, radiation therapy near the eye and certain eye diseases.年齡，家族病史，吸煙，糖尿病，傷害到眼睛，長期使用類固醇，放射治療附近的眼睛和某些眼疾。
Lens Implant : 鏡頭種植體：
One way to understand exactly what cataracts are is to compare the lens of the eye to a camera lens.方法之一，準確地了解白內障是比較眼球晶狀體對一個鏡頭。 If a camera lens were dirty or hazy, it would not take a clear a picture.如果一個鏡頭被弄髒或有煙霞，它不會採取明確的一張圖片。 The camera repair shop would remove the lens and put a new one in its place.相機修理店將消除鏡頭，把一個新在它的位置。 This is similar to how cataracts are repaired.這是類似白內障是如何修復。 The eye's lens is surgically removed and replaced with a new, clear lens, called a lens implant.眼睛的鏡頭是手術拆除，並代之以一個新的，明確的鏡頭，所謂的鏡頭植入。
Cataract Surgery : 白內障手術：
In the early stages of cataract development, vision may not suffer significantly and cataract surgery is not necessary.在早期階段，白內障發展，視力可能不會受到顯著和白內障手術是沒有必要的。 Often as cataracts develop, changing the person's glasses prescription is all that is needed for good vision.經常性白內障的發展，改變人的眼鏡處方是所有這一切都是需要良好的視野。
Cataract surgery is indicated only when the lens clouds so much that a person has difficulty reading or driving.白內障手術是表示，只有當鏡頭雲這麼多認為，一個人有困難，讀或駕駛。
If you are told that you need cataract surgery but your vision is fine, be a little cautious and, perhaps, seek a second opinion. 如果你是說你需要白內障手術，但您的願景是好的，是一個不大謹慎，或許，尋求第二意見。
Additionally, there is no such thing as emergency or urgent cataract surgery, so if a doctor tells you that you need surgery at once, you may want to get a second opinion, as well.此外，有沒有這樣的事，作為緊急情況或緊急白內障手術，因此，如果醫生告訴你，你需要外科手術一次，您可能會想要得到的第二個意見，以及。
Surgery is the treatment for cataracts when they become significant.外科手術是治療白內障時，他們成為重要的。 Maximizing glasses can help in the early stages; however, the use of vitamin and nutritional supplements and "cataract eye drops" has not been thoroughly studied, and none of those treatments seem to help very much.最大限度地眼鏡，可以幫助在早期階段，但是，使用維生素和營養補品和“白內障滴眼液”並未深入的研究，並沒有這些治療似乎幫助不大。
The surgery has come a long way from the days when a patient was hospitalized for as long as two weeks.手術已走過了漫長的道路，從天當病人住院，因為只要兩個星期。 Today, it is performed on an outpatient basis, in an ambulatory surgery center.今天，它的表現是對門診的基礎上，在一個門診手術中心。 Preparing for the surgery takes most of the time.準備手術需時，大部分的時間。 The patient receives multiple sets of eye drops, the eye is cleansed and the patient is given an IV.病人收到多套眼藥水，眼睛是清洗和病人是由於一四。
The surgery is done while the patient is awake, but he or she may be mildly sedated with what is known as "twilight anesthesia."手術是做的同時，病人是清醒，但他或她可能是輕度鎮靜與什麼是被稱為“曙光麻醉” 。 There should be no pain, and the operation takes about ten minutes.不應該有疼痛，和運作需時約10分鐘。 Shortly after the operation, the patient is able to go home.在短期內手術後，病人是能夠返回家園。
Cataract surgery is the most commonly performed operation in the US; however, complications, such as infection, can occur.白內障手術是最常見的演出運作，在美國，但並發症，如感染，就可能發生。
Even though they're rare, complications do happen, so surgery should be done only when a person's vision is significantly impaired. 即使它們罕見，並發症的發生，所以手術應該做的事，只有當一個人的願景是顯著受損。 As the old saying goes: if it's not broken, don't fix it. 正如古語有雲：如果它不打破，不解決它。
