糖尿病患者白内障治疗（Cataract treatment in diabetic patients） Cataract treatment in diabetic patients Cataract refers to the opacity of the lens. It can be divided into cortical cataract, nuclear cataract and capsular cataract according to the location of turbidity. Generally speaking, the capsular cataract usually occurs in the pupillary region, which has a greater impact on vision, and can lead to visual impairment earlier. However, visual acuity is more late in cortical cataract and nuclear cataract. I. the particularity of cataract in diabetics The cataract in diabetic patients belongs to metabolic cataract, and there are two states. One is true diabetic cataract (which belongs to metabolic cataract). This is due to diabetes, biochemical abnormalities caused by internal environmental cataract. This cataract is rare, with the highest incidence of diabetes in middle-aged and young people, is also common in children with diabetes. The true diabetic cataract is to start from the small vacuoles of anterior capsule of lens under intensive form, along with the development of the disease, small vacuoles can quickly become the typical white spots patchy opacities, the anterior and posterior subcapsular superficial cortex. Since then, the extent of patchy opacities has expanded evenly in the cortex, as if snowflakes were floating in the gray sky, known as snowflake opacity.. Subsequently developed into a fully cloudy state. Another condition is similar to age-related cataracts. It is difficult to make an accurate distinction between diabetes and elderly factors in cataracts that occur after middle age in diabetics. But by the characteristics of diabetic cataract with all senile cataract in morphology, there is much evidence to support such a phenomenon, namely diabetes factors can make the early appearance of senile cataract or accelerated development. In the course of cataract development in diabetic patients, the characteristic pathological changes are the rapid edema of the matr
