How should 90-year-old people treat cataract?

1. How to treat cataract in 90-year-old people?

1, drug therapy

Vitamin C, vitamin B2 and vitamin E can be taken orally. You can also use the eye drops of Bainaiting, Baikeming, catherine and Fakelin. There are many drugs for treating cataract in clinic, but there is no effective drug at present.

2. Surgical treatment of cataract

Since the development of cataract microsurgery, the methods of cataract extraction have been continuously improved. From the traditional extracapsular cataract extraction to the advanced cold phacoemulsification, it has changed from large incision to small incision. The former has a large incision, while the latter has a small incision, small postoperative astigmatism, rapid postoperative visual recovery and low incidence of intraoperative and postoperative complications. If an accidental injury occurs after the operation, the original wound will not rupture.

If the vision of cataract patients drops to 0.5 or below, cataract surgery is recommended. Vision can be restored by surgery, removal of turbid lens and implantation of intraocular lens. Of course, for cataract patients with high vision requirements, cold phacoemulsification can also be performed at the early stage of cataract.

Cataract cannot rely on drugs, and the best treatment is prevention. Pay attention to eye protection, prevent radiation damage to eyes, appropriately increase nutrition, pay attention to rest, keep enough sleep, keep an open mind, be optimistic and cheerful, and pay attention to controlling emotions.

Second, how do the elderly prevent cataracts?

1, pay attention to psychological adjustment

Treat things calmly, be broad-minded, keep a good mood and control anger. Cultivating the interest in raising flowers, birds and goldfish to cultivate sentiment and talking with young people can distract attention from unpleasant things, stimulate strong enthusiasm for life and play a role in preventing and delaying the progress of the disease.

2. Strengthen eye hygiene.

Usually you don't have to rub your eyes, wipe your eyes, and wash your eyes with dirty handkerchiefs and towels. After excessive eye use, sedentary people should get up and exercise 10 ~ 15 minutes, with an interval of 1 ~ 2 hours, and look up and do eye exercises. Get enough sleep and recover from fatigue in time.

3. Actively prevent and treat chronic diseases.

Including eye diseases and systemic diseases. In particular, diabetes is most likely to be complicated with cataract, so it is necessary to control blood sugar in time and effectively to prevent the further development of the disease.

4. Diet should be rich in protein, calcium and trace elements.

Eating more foods containing vitamins A, B, C and D, and eating more fish at ordinary times can maintain normal vision and slow down the progress of the disease.

Three, five early symptoms of senile cataract

Old people will have obvious symptoms after suffering from cataract. If you or your family have these symptoms, you must go to the hospital for examination and treatment in time. Don't delay. The later the cataract is discovered, the more difficult it is to treat.

1, presbyopia decreased

Presbyopia is reduced. Some elderly people usually need to wear reading glasses when reading books and newspapers, but they will suddenly find that they don't need to wear reading glasses when they see things. Some old people are happy. In fact, this is not a good sign. This is because the lens convexity increases and the refractive near point changes at the initial onset of senile cataract, which is one of the early symptoms of cataract.

2, blurred vision

Blurred vision, blurred vision gradually. Sometimes, you will feel that there is an aperture around the light and the color of the object is not bright enough. If cataract patients drive at night, they will feel that the headlights coming from the opposite car are too dazzling, and they feel uncomfortable or irritable. But generally speaking, the development process of early symptoms of cataract is quite slow, depending on the most turbid position of lens and its development process.

3. The shadow in front of you

In the early stage of cataract, part of the opacity of the lens is located in the pupil area, and there may be spot or flake shadows with fixed position and unchanged shape in front of the eyes. It is different from floaters caused by vitreous opacity. The shadow of the latter is movable. Although the range of activities is not large, it is hidden and changeable.

4. Abnormal color vision

Color vision is abnormal. In the early stage of cataract, the lens swells due to absorbing more water, and the gap between epithelial cells is enlarged, filled with particles and water droplets. When the light passes through it, it will be refracted, showing a colorful halo, commonly known as rainbow vision.

5. Day blindness or night blindness

Sun blindness or night blindness, if the lens opacity starts from the central part first, when the light intensity and pupil shrink during the day, the light is blocked from entering the eyes, thus causing sun blindness; For example, lens opacity is located in the peripheral part, dark light is blocked from entering the equatorial retina at night, and rod-shaped visual cells in the equatorial retina specialize in liquid vision, so liquid blindness will occur, which is also one of the early symptoms of cataract.
