Cataract is a very common eye disease, no matter in our country or in the world, is one of the main causes of blindness. There are various rumors about cataract circulating on the Internet, TV, advertisements and neighbors. Many patients cannot distinguish right from wrong, and even delay their illness. What is cataract? How should it be treated? Which rumors are simply unreliable? Myth 1: Only the elderly will get cataract? In our eyes, The lens that acts as a lens, Turbidity has occurred, This condition is called cataract. In fact, There are many causes of cataracts. Among them, Cataracts that are closely related to age are the most common, This type of cataract is called senile cataract or age-related cataract. It can happen to the middle-aged and the elderly. However, There are many types of cataracts such as congenital cataract, traumatic cataract and complicated cataract. Compared with senile cataract, Apart from the cause of the disease, they may also have some differences in treatment. Never think that young people will not get cataracts, nor do you think cataracts are a manifestation of [aging], thus denying and allowing the development of the disease and delaying treatment. Myth 2: Floaters are caused by cataracts? Flying mosquitoes, As the name implies, Even if there is a small black shadow in front of us, They are irregular in shape, It may be like mosquitoes, black spots, black lines, flowers or even spiders. The main feature is fluttering. It is caused by turbidity of vitreous tissue in the eyeball. Unlike cataract lesions, vitreous body is a transparent jelly-like substance composed of collagen fibers. It can shake slightly like jelly, The muddy part inside can also float along with it, Formation of floaters. This shows that the two kinds of turbidity occur in different parts of the eye, which is not the same thing at all. However, in the middle-aged and elderly people, they often exist at the same time. After the turbid lens is removed by surgery, floaters will not disappear and may be more obvious. Myth 3: Can eye drops cure cataracts? For many years, people have been looking for effective drugs to treat cataract. A lot of research has been done. Unfortunately, At present, worldwide, No drug has been proved to be effective in treating or slowing down the development of cataracts. Now, the surgical treatment technology for cataracts is very mature. Instead of relying on various unreliable eye drops or drugs, it is better to visit the hospital regularly to see if the requirements for surgery have been met. Myth 4: Cataracts can only be done after they are [ripe]. Can they be delayed as much as possible? In fact, this is an era when surgical techniques and equipment are backward. A misunderstanding that has been handed down. Now, There are two main methods of cataract surgery: Extracapsular extraction and phacoemulsification. The method of extracapsular extraction, It’s like pulling out the whole core from the longan, A bigger incision is needed, There are also more risks and complications of surgery. However, phacoemulsification and aspiration, Is to use ultrasonic energy to break the core into small pieces, And suck them out one by one, Its incision is small, its speed is fast, The improvement of vision after surgery is often more obvious. As long as the corresponding equipment is available, Phacoemulsification is naturally the first choice. However, If the patient is misled by this statement, Drag it until it’s almost out of sight, Cataracts can be too familiar, It cannot be sucked off by phacoemulsification, Instead, it should be done by [picking out the nucleus]. Cataracts can also lead to glaucoma. Or aggravate the development of glaucoma. Once glaucoma occurs, It causes visual impairment, Probably far worse than cataracts, And it is difficult to recover. Severe cloudy cataracts are in the channels through which light enters the eyes. Is a huge obstacle, It will block the retina and other tissues behind it. As a result, doctors cannot detect fundus lesions. Some patients did not undergo cataract surgery until after cataract surgery. Only to find that there is a serious problem in the fundus, But it was too late. Besides, As you get older, Many older people suffer from other physical illnesses, Common such as cardiovascular diseases, diabetes, etc. If cataract caused by vision loss and other symptoms have affected normal life, doctors also suggest surgery, please try to do it when you are in good health, the risk of surgery is definitely lower than delay to do later. Myth 5: Cataract surgery must be able to see clearly? For most patients, Cataract surgery can improve vision faster and more obviously. Therefore, it is generally believed that, After cataract surgery, you can see clearly. In fact, it is not, This needs to be analyzed on a case-by-case basis. If there are other eye diseases, Especially in the fundus, Then the eyesight may still not be ideal after the operation. At this time, Further treatment may be needed for these eye diseases. In most cases, At the same time as the opaque lens was removed, An intraocular lens needs to be implanted, To continue to play the role of [lens]. If there are some special reasons such as lens dislocation and fundus lesions, The intraocular lens cannot be implanted for the time being, Then the vision will still be blurred after the operation. Besides, Due to the decline of eye regulation function in the middle-aged and elderly people, There is presbyopia, which may be more obvious after the operation. There may also be myopia, farsightedness or astigmatism after the operation. These can often be solved by wearing glasses. Once, an old woman said happily after cataract surgery, “I have seen my granddaughter clearly!” It turns out that she is so beautiful! It turns out that a clear world can not only make life more convenient for patients, but also have more sustenance in spirit. This has become an important consideration in deciding cataract treatment methods, that is, improving the quality of life of patients.
