Cataract is one of the common eye diseases caused by the clouding of the lens in the eye, resulting in visual impairment. It is one of the common eye diseases, especially one of the diseases of the elderly. The human eye is like a camera, and its lens is like the lens of the camera. The lens can be adjusted to allow people to see objects near and far, and the lens is supposed to be colorless and transparent, and its main component is protein, which is known to be irreversible once denaturation occurs. So far, there is no cure for cataracts worldwide, nor is there any method or drug that can keep cataracts from progressing. At present, there are a lot of cataract treatment drugs produced at home and abroad, such as domestic cataract stop, imported carlin and glutathione, etc. However, years of clinical practice in ophthalmology have proved that using them is useless, and it is recognized by the ophthalmology profession that the treatment of cataract by drugs is still an exploration. The use of it is just a placebo. In China, there are many Chinese medicines that can be used to treat cataract, such as Dendrobium Luminosum Pill is one of the representatives, but the effect is very little or almost ineffective. In recent years, there are many “eye patches”, some of which are blown out of proportion and said to be panacea and can cure cataract at all, but in reality they are useless. Many people suffering from cataract spend thousands of dollars or even tens of thousands of dollars to use these miracle patches because they are afraid of surgery, but it is all in vain. As a result, they spend a lot of money and do not get cured. Some of them delay the best surgery period and live with low vision for years, which greatly reduces their quality of life and even causes serious complications. The best way to treat cataracts is surgery. It is a one-time cure. Modern advances in ophthalmology have made cataract a safe surgery, and there is no need to wait until you can’t see and then operate, as in the past, you can receive surgery according to your vision requirements and the degree of cataract. The purpose of this article is to remind patients not to listen to “advertisements” and to receive cataract treatment scientifically.
