Cataracts are classified as diabetic cataracts or senile cataracts. If a diabetic patient develops cataracts, consider them to be diabetes-related cataracts, which would be a complication of diabetes. Some patients with better glycemic control still have cataracts when they get older, and the examination suggests senile cataracts, which are not very related to blood sugar. Whether it is senile cataract or diabetes-related cataract, it is usually necessary to go to ophthalmology to take surgery to treat cataract. In the early stage of cataract, the effect on vision may not be obvious, so surgery can be temporarily disregarded. If the cataract obviously affects the vision, go to the ophthalmology department for treatment in time.
