What Is a Cataract Incision?

Cataract is a common blinding eye disease. There is a tissue in the human eye called the lens. Under normal conditions, it is transparent. Light passes through it and some refractive interstitials to reach the retina, so that you can clearly see external objects. Once the lens becomes cloudy for some reason, it will affect the retina imaging, making people unable to see clearly. In other words, opacity caused by lens opacity is cataract. It is recommended to treat promptly when cataract is found or diagnosed, and to avoid long-term excessive eye use.

Life prevention

1. Pay attention to mental adjustment: Be calm when you have an incident, keep your mind wide, keep your mood comfortable, and control your anger. Cultivate interest in raising flowers, birds, and goldfish to cultivate sentiment, talk to young people, distract attention from unpleasant things, stir up a strong enthusiasm for life, and play a role in stopping and delaying the progress of the disease. 2. Strengthen eye hygiene. Do not rub your eyes with your hands, do not clean your eyes with handkerchiefs, towels, or wash your eyes. After using the eyes excessively, you should relax appropriately. Sedentary workers should get up for 10 to 15 minutes at an interval of 1-2 hours, look up, or do eye exercises. Get enough sleep and recover from fatigue in a timely manner.

3. Actively prevent and treat chronic diseases, including eye diseases and systemic diseases. In particular, diabetes is most likely to be complicated by cataracts. It is necessary to control blood glucose in a timely and effective manner to prevent further development of the disease.

4. Diet should be rich in protein, calcium, trace elements, eat more foods containing vitamins A, B, C, D. Usually eat more fish, can maintain normal vision and retard the progress of the disease.

5. Smoking is susceptible to cataracts and has been proven by practice. Quit smoking early.

Food diet

(1) Eat more fresh vegetables and fruits rich in natural vitamin C, such as celery, cabbage, greens, tomatoes, strawberries, oranges, fresh dates and so on.

(2) Eat more food, green vegetables and lettuce, carrots and tomatoes, especially citrus fruits, grapes, lemons, bananas, and apricots. Also eat calcium foods often.

(3) Avoid drinking and smoking, and eat less animal fat and sugar.

The main symptoms of cataract are vision loss, blurred vision, fixed dark shadows in front of the eyes,

The natural lens has a capsular bag, that is, the lens capsule. According to the relationship between the nucleus of the lens and the capsular bag during surgical removal, it is divided into intracapsular extraction and extracapsular removal. After removing turbid crystals, it is often necessary to put one

Cataract surgery has a wide range of indications, and all types of cataracts suitable for Fuming surgery can be treated with surgery:

1. Those with opaque crystals and vision below 0.3, including corrected vision.

2. Regardless of the eyesight, as long as the patient has high requirements for vision or has special occupational requirements.

3. Dislocation and subluxation of crystals.

4. High myopia with cataract.

5. Congenital cataracts of all ages.

6. Cataracts due to inflammation must be controlled for more than six months.

7. Traumatic cataract.

8. Cataract merger

Cataract surgery preoperative examination

Cataract patients are frail for many years and have multiple diseases throughout the body. In order to make the operation successful and prevent complications, some necessary local and systemic examinations should be performed before the operation.

Routine inspection

Eye examination before cataract surgery should include visual function (light perception, light positioning,

1. Take a car home after surgery to avoid bumps.

2. Drop the eyedrops on time. Wash your hands before dispensing. Do not touch the eyes and hands to prevent contamination. When applying medicine, pull down the eyelid by hand (the surgical incision is on the upper part, do not pull on the upper eyelid), and instill the eyedrops. If you need to use more than two eyedrops, the interval is 10-15 minutes.

3. Quit smoking and alcohol after surgery, do not eat spicy and irritating food, eat more fruits and vegetables, and maintain smooth stool.

4. The surgical incision heals in about three weeks (patients with diabetes should also extend the time appropriately). During this period, wash your face and shampoo. Do not let sewage enter the eyes of the surgery to prevent infection.

5. Try not to cough hard after surgery. Surgical eyes are strictly forbidden from impacting, pressing, lowering their heads, and rubbing their eyes. Siesta and nocturnal sleep should be supine or lying on the side of non-surgical eyes, and wear eye masks to prevent eye injury.

6. Avoid lifting heavy objects, strenuous exercise, and prevent eye pressure fluctuations.

7. Windproof sand when going out, you can wear glasses, etc. to prevent foreign objects from entering the eyes.

8. Avoid reading books and newspapers for a long time during the recovery period to prevent eye fatigue.

9. People with high blood pressure and diabetes should keep taking medicine.

10. Follow the doctor's advice to the hospital for review after surgery. If there are sudden changes in vision, swelling, pain and other symptoms, you should see a doctor immediately.

Postoperative cataract complications

Multiple complications can occur after cataract surgery, and the symptoms must be treated symptomatically.

(1) Shallow anterior chamber caused by incision leakage after cataract surgery;

(2)

Phacoemulsification lens removal +

For more than a century, anaesthesia methods for cataract surgery have been dominated by post-ball anesthesia or per-ball anesthesia, but some potential complications can still occur, such as post-ball hemorrhage, increased intraocular pressure,

Three Misunderstandings of Surgery

Cataract is a common eye disease. If not treated early, it may lead to severe consequences of blindness. Therefore, it is very important to treat cataracts as early as possible. The best way to treat cataracts is through cataract surgery. However, there are still many people who have three major misunderstandings about cataract surgery. Today I will introduce them one by one:

1. Some cataract patients were told that they would "see surgery before they were invisible", so they waited patiently and did not get regular inspections at the hospital. As a result, I don't know about other eye diseases, such as chronic angle-closure glaucoma, macular degeneration, fundus and vitreous hemorrhage, etc.

When the vision is severely impaired, the above-mentioned diseases have developed to a more serious degree, and the best time for treatment has been missed. In this case, even if surgery is performed, satisfactory vision cannot be restored.

2. The traditional concept in the past is that surgery can only be performed after the cataract has matured. This is particularly cruel for patients with binocular cataracts, because these patients have to wait a long time in the hazy world to regain their light. They lost many job opportunities and life fun.

With the development of modern medicine, ophthalmic microsurgery has become very mature and common. Modern extracapsular cataract extraction and crystal phacoemulsification technology can make immature cataracts obtain good treatment results. Therefore, in order to improve the quality of life, cataract patients can accept surgery when they feel that their visual impairment has affected their normal work or life, and do not have to wait until the cataract matures.

3. Cataract often occurs unknowingly and develops slowly. Many elderly people think that distant objects are not as clear as before.
