With the development of medical technology, performing cataract surgery on diabetic patients is no longer a difficult task. However, due to the presence of diabetes, the chances of complications such as bleeding and infection increase, and the risks of surgery are relatively greater than those of normal people. Moreover, due to the combined diabetic fundopathy, there is a risk of unsatisfactory postoperative vision recovery and aggravation of postoperative fundopathy. Before having surgery, diabetic patients must do various corresponding examinations and evaluate all indicators comprehensively and comprehensively in order to reduce the risk of surgery.
First, blood sugar should be controlled under the guidance of a specialist to keep it stable. Second, a detailed eye examination should be done, especially visual function and fundus examination. Because fundus changes seriously affect the post-operative vision of diabetic patients, different stages of fundus lesions have different degrees of impact on visual function. Knowing the degree of fundus lesions can predict the vision condition after cataract surgery, and the doctor can give appropriate treatment according to the patient’s eye condition. Third, preoperative physical examination: check blood pressure, electrocardiogram, chest X-ray, liver and kidney function to exclude systemic diseases and ensure the safety of surgical procedure and postoperative medication.
