Cataract is caused by the opacity of the original transparent lens of the human eye, and the inability of light to enter the eye, resulting in decreased vision and serious blindness. Cataract surgery removes these cloudy lenses, and then implants an intraocular lens in the capsular bag of the lens. The removed things will not grow.

　　 but some people do have cataract surgery The visual acuity has dropped again. What''s going on? This is because of the cloudiness of the posterior capsule. So, old friends want to ask, what is the posterior capsule? Since it is easy to be cloudy, why not remove it during surgery? The posterior capsule is the outermost layer of cataract, which must be completely preserved during surgery and is used to support the intraocular lens .

　　This is the case. Don’t be afraid. The treatment is very simple. Use the YAG laser to remove the central part of the opaque posterior capsule to allow light to enter the eye and restore vision. The laser can be performed in the outpatient clinic without hospitalization, just a few minutes, without any pain, it is also very safe, the cost is about 200 to 300 yuan.

　　The incidence of posterior capsule opacity is very different in patients of different ages. Due to their relatively strong ability to proliferate, the posterior capsule opacity occurs in almost 100% of patients with congenital cataract. The incidence of young patients will also be higher. The postoperative incidence of elderly patients is about 3 to 10%.

　　It is necessary to remind everyone that if there is a decline in vision after cataract surgery, first of all, you should go to the hospital in time to make a clear diagnosis. There are many causes of vision loss. The eyeball is a complex organ, prone to various eye diseases, and the elderly are very susceptible to diseases due to age, just like other organs of the body. Among them, various types of fundus diseases most often occur in the elderly. If you have a fundus disease, you need further treatment, and you must not delay the timing of treatment.

　　This reminds us that after cataract surgery can not be ignored for a long time, it should be reviewed regularly, and problems should be discovered and treated in time.
