When to have cataract surgery? When to seek medical consultation?
Cataract is a disease that occurs in the lens inside the eye. All causes such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause disorders in lens metabolism, resulting in clouding of the lens proteins due to degeneration, called cataract. The main symptom of cataract is visual impairment, which is related to the degree and location of lens clouding.
Cataract is a manifestation of aging and everyone cannot escape it, but because its clouding occurs at different sites and the degree of clouding is different, we perceive it at different times, therefore, some people have blurred vision in their 40s and some people start to lose their vision only at the age of 80. Unstable blood sugar, hyperglycemia and hyperlipidemia in diabetic patients can aggravate and accelerate the development of cataracts, and blurred vision, which appears like seeing through woolen glass. When vision loss occurs, you need to see an ophthalmologist to determine if it is due to cataracts.

In Beijing, the vast majority of hospitals have carried out ultrasonic cataract extraction combined with IOL implantation, which is accepted for its small incision, no stitches, quick recovery and painlessness. “If we still stick to the old concept, it will increase the risk of surgery and inevitably increase the stimulation and damage to normal tissues during surgery.
