In middle age, myopia deepens and cataracts need to be vigilant

Abstract: some cataract patients will have day blindness or night blindness. This is because in the early stage of cataract, part of the opacity of the lens is located in the pupil area, and spot or sheet shadows with fixed position and unchanged shape can appear in front of the eyes. It is different from the flying mosquito disease caused by vitreous opacity. The shadow of the latter is movable. Although the range of activity is small, it looms and appears from time to time and its shape is changeable.

cataract patients tend to be younger. Cataract patients aged 40 to 50 accounted for a small proportion of the overall patients 10 years ago, which has increased in recent years. It is believed that it is related to the serious problem of myopia in young people. Because the continuous increase of myopia in childhood will continuously lengthen the eyeball and increase the risk of early cataract in adulthood.

and

most people’s myopia will stop deepening when they are in their 20s, but some people’s myopia will suddenly deepen when they are in their 30s, and the deepening speed is very fast. For example, it will deepen more than 100 degrees every year. After examination, it is found that it is cataract that increases the density of eye lens and the degree of myopia will rise accordingly. Therefore, myopia is closely related to cataract.

six symptoms in the early stage of cataract

refers to the damage of cataract to the eyes. It is believed that cataract will not only deepen the degree of myopia, but also have six symptoms in the early stage. They are as follows: monocular multi vision, that is, in the early stage of cataract, the lens is turbid and partially transparent, and the object image projected on the retina through it will produce double shadow or multi shadow; Abnormal color vision, that is, in the early stage of cataract, due to the swelling of the lens due to the absorption of more water, the epithelial cell gap is enlarged and filled with particulate water droplets. When light passes through it, it will be refracted and show color halo, commonly known as rainbow; The vision is blurred, and the vision is gradually blurred. Sometimes I feel that there is an aperture around the light and the color of the object is not bright enough. If you drive at night, you will feel uncomfortable or irritable because the headlights of the car coming from the opposite side are too dazzling. However, generally speaking, the development of symptoms is quite slow, depending on the location of the most turbid lens and its development process.

in addition to the above symptoms, cataracts may also lead to the reduction of presbyopia. Some elderly people usually need to wear presbyopia glasses to read books and newspapers, but suddenly they find that they don’t need presbyopia glasses to see clearly. Some elderly people are very happy. In fact, this is not a good sign because the lens bulge increases at the beginning of senile cataract, The change of near refractive point is one of the early symptoms of cataract. In addition, some cataract patients will have day blindness or night blindness. This is because in the early stage of cataract, part of the opacity of the lens is located in the pupil area, and spot or sheet shadows with fixed position and unchanged shape can appear in front of the eyes. It is different from the flying mosquito disease caused by vitreous opacity. The shadow of the latter is movable. Although the range of activity is small, it looms and appears from time to time and its shape is changeable.

suffering from cataract must be treated in time, because cataract will induce glaucoma. Glaucoma has a greater impact on people’s vision and a greater probability of blindness. We must pay attention to and prevent it. What do you know about the “misunderstanding” of cataract? Misunderstanding 1 of

and

: cataract is a refractory disease. Many patients regard cataract as a scourge and believe that there is a risk of blindness in treatment, so they choose to muddle along. In fact, the treatment of cataract is not as terrible as people think. The operation of sucking out the turbid lens and inserting a transparent intraocular lens is very mature. Not only will the patient not escape into the dark, on the contrary, after a short operation, the patient can see the world clearly. Misunderstanding 2 of

and

: drugs can effectively treat cataract. The effective way to treat cataract is surgery. Drug treatment of cataract has no obvious effect. Some early cataract patients may say that after medication, they feel that the disease has developed slowly and their vision has improved. This is not necessarily the result of drug treatment, because cataract is a long process from early development to maturity. It may stop naturally at a certain stage without seriously affecting vision.

and

have proved clinically that drug treatment has no significance for cataract patients who are close to maturity. Experts remind cataract patients not to believe that drugs can treat cataract, let alone superstitious prescriptions, otherwise, they will not only fail to achieve the treatment effect, but also delay their condition. Misunderstanding 3 of

and

: cataract is not painful or itchy. Don’t worry. Many people suffer from cataract, although their eyesight is getting worse and worse, they do not actively treat it. They think it doesn’t matter whether they are treated or not when they are older. Although cataract is not life-threatening like cardiovascular and cerebrovascular diseases, it will cause low vision and even blindness, which will seriously affect the life of patients, and it is easy to cause other eye complications for a long time. Timely surgery can not only improve the vision of cataract patients, but also improve their quality of life. Misunderstanding 4 of

and

: great surgical trauma. In the past, cataract surgery was performed with an incision of 11mm, and the operation time was one hour or more. The postoperative patients had to be hospitalized for seven days, and the postoperative effect was poor. The current cataract phacoemulsification only needs to open a small opening of 2 ~ 6mm, and the operation time is 5 ~ 10 minutes. The patients have fast wound healing, rapid visual recovery and less complications.
