What is a cataract? What is a cataract?

Clouding occurs due to deformation of the lens proteins due to various reasons, known as cataracts. In the eyeball model, the transparent part at the front, which is called the black eyeball, is actually the cornea. At the back of the cornea, there is a biconvex lens, and it is because of the opacity of this lens that cataracts are formed.

The most common reason is that as we age, the protein degeneration becomes cloudy, which affects the quality of vision and in severe cases, blindness.

Various causes such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, as well as trauma, poisoning, radiation, etc., can cause lens metabolism disorders, resulting in lens protein denaturation and clouding, causing cataracts.

All kinds of causes such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolism disorders, resulting in lens protein degeneration and cloudiness, called cataracts, at this time the light is blocked by the cloudy lens can not be projected on the retina, and objects cannot be seen clearly.

From the perspective of population blindness prevention and treatment, the World Health Organization (WHO) has degenerated and clouded the lens, becoming opaque, and even affecting vision, and only those with corrected visual acuity or less are classified as cataract diagnosis.

**Cataract, come to Aier Eye Hospital, Aier Eye Hospital Group is an ophthalmic medical group with the scale of hospitals in China and around the world, and high-quality medical capabilities, which can better help you solve eye troubles and be your eye steward.

Cataract is a common eye disease, which is called cataract when the human body causes lens metabolism disorders due to various reasons such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., resulting in lens protein degeneration and cloudiness.

Cataract is an eye disease that the elderly are prone to, and after getting the disease, there will be blurred vision, deformation or a sense of obstruction, etc., and in severe cases, they will be blind, which will greatly affect their daily life, and even inconvenience such as being unable to take care of themselves and needing to be taken care of by others.

In medical terms, cataract is the clouding of the lens, and there is a refractive body in the eye, which is a transparent body of the jujube karyotype. Light passes through it to focus on the retina. However, this transparent body becomes gradually opaque and completely turbid from the original transparent, which is called cataract at this time, which affects people's ability to see things.

All various causes such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolism disorders, resulting in lens protein denaturation and clouding, called cataracts, at this time, the light is blocked by the cloudy lens and cannot be projected on the retina, resulting in blurred vision. It is more common in people over 40 years of age, and the incidence increases with age.

A cataract is a clouding of the lens. Thus affecting vision. Well, the disease is particularly simple, and so far there is no effective way to stop the cataract from progressing further. Only surgery can be done to improve vision.

Cataract is not a disease of the eye, so if you have cataract, you should go to the hospital as soon as possible, uh, to prevent it from becoming more serious.

Cataract is more common in the elderly, generally speaking, it is a layer of things in the eye, which affects vision, this can be operated on, and it is not a special major disease?

Cataract is one of the most common diseases in ophthalmology, and it is currently the most common blinding eye disease in China, and the incidence of cataract will increase year by year with age.

The main symptoms of cataract are progressive vision loss, and in the early stage of the disease, there may be an increase in myopia and astigmatism, glare and other uncomfortable phenomena. When cataracts progress to an advanced stage, they can lead to severe vision loss, and the patient's vision can even be reduced to the point where they can only distinguish the light and dark of their surroundings and the shaking of their hands.

The loss of vision caused by cataract can be recovered through **, and it is necessary to remove the cloudy lens inside the eyeball through surgery and replace it with a transparent intraocular lens, so that the factors that hinder light from entering the inside of the eye are removed, and the vision can be improved.

Cataract is a disease that occurs on the lens of the eyeball, all causes such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolism disorders, resulting in lens protein denaturation and clouding, called cataract. At this time, the light is blocked by the cloudy lens and cannot be projected on the retina, so the object cannot be seen clearly. However, when the lens opacity is mild, it does not significantly affect vision without being noticed or ignored and is not included in the cataract category.

According to surveys, cataracts are the most common cause of blindness and visual disability, with about 25% of humans suffering from cataracts. The World Health Organization (WHO) from the perspective of population blindness prevention and treatment of blindness, the lens is degenerated and clouded, and becomes opaque, so as to affect vision, and the corrected visual acuity is at or below is classified into the scope of cataract diagnosis. Cataract is the leading cause of blindness and vision impairment worldwide, mostly in people over the age of 50, and will be increasingly caused by cataract as the population grows and ages.

Cataract blindness can generally cause blindness, and cataract surgery before vision is significantly impaired can greatly reduce the number of blind and low-vision patients.

Generally speaking, with the increase of age, the adjustment of the lens decreases, and the process of decline is the process of aging, and at this time, there will be blindness. Then there will be a yellowing and then whitening of the lens, which is called a cataract.

Anything that causes the lens to be cloudy and cause vision to deteriorate is a cataract. It may be related to aging, nutritional disorders, metabolic disorders, ultraviolet radiation, poisoning, trauma, genetics and other factors. The extra-lens capsule is damaged, loses its barrier effect, and aqueous humor enters the lens, denaturing the lens proteins, causing turbidity.

Specifically, you can go to the Xiamen Eye Center in Quanzhou to have a look.

Cataract refers to the turbidity of the transparent lens, the causes of which include aging, physical damage, chemical damage, drugs, inflammation and tumors, etc., age-related cataract is the most common, and the main clinical manifestations of cataract are as follows: 1. Vision loss: progressive ** vision loss, in severe cases, only by light sense; 2. Double vision:

Monocular diplopia is easily overlooked; 3. Myopia; 4. Glare; 5. Visual field defect: due to the different locations of the lens opacity, the opacity may lead to visual field loss.

Cataract is a clouding of the lens due to aging, systemic metabolic diseases, or eye diseases, and is caused by abnormal nutrient metabolism of the lens. When cataracts occur, patients experience blurred vision, decreased vision, and double vision. Over time, the symptoms of cataracts can gradually worsen.

In the human eye, there is a tissue called the lens, which plays the role of regulating refractive power. It is transparent on its own, but for various reasons, it is denatured and opabidden, and interference prevents light from passing through, which causes cataracts. Among the various types of cataracts, age-related cataracts are the most common, which is closely related to aging, and the probability of developing cataracts increases dramatically once you enter old age.

It can even be said that everyone will suffer from cataracts as long as they reach age. Xi'an Aier Ophthalmology Wang Licao.

There is a lens in the eye, similar to a camera lens, which is normally colorless, transparent and elastic, and through its light-concentrating effect, it allows us to see both far and near. When the lens becomes cloudy and changes from transparent to opaque, it prevents light from entering the eye and affects vision, which is called cataract. Cataracts have little effect on vision in the early stages, but as the lens becomes more cloudy, vision gradually decreases, and if left unchecked, it can eventually lead to blindness.

If the lens in the eye is cloudy, the surgery can be done to change the lens, which is a minor operation and can be done in half an hour.

Cataracts are caused by clouding of the lens. Because our lens also "retires", with the increase of age or trauma and other reasons, the lens of the human eye will gradually become cloudy, and light cannot be transmitted, resulting in vision loss. In other words, the culprit of cataracts is the lens.

Surgery is currently the only effective way to cataract, and phacoemulsification combined with intraocular lens implantation is the most common. In general, our intraocular lenses can be divided into three categories: monofocal, multifocal and continuous visual range intraocular lenses. Of course, not all cataract patients need immediate surgery, and it is necessary to go to a professional medical institution for diagnosis and examination to ensure the best results.
