There are currently 40 million diabetic patients in my country, of which 25% have varying degrees of diabetic retinopathy and require vitreous and retinal surgery. Affected by the perception that the wounds of diabetic patients are not easy to heal when undergoing major surgical operations, many people still have the wrong perception that “diabetics cannot accept eye surgery”, which affects or seriously delays The treatment of many eye diseases affects the quality of life of patients and even causes blindness in some people. In fact, diabetes complicated by eye diseases requires eye surgery, but it must be done under the premise of good blood sugar level control.
Incision healing is minimally affected by diabetes
Skin incisions in major surgery are generally relatively large, and wound healing from the growth of granulation tissue to the formation of collagen fibers requires the participation of protein and other tissue factors. Diabetes patients have abnormal sugar utilization, which cannot effectively convert glucose into protein and other substances. Hyperglycemia in tissues leads to hypertonicity of cells, which impairs the regeneration and repair function of tissues, which results in delayed wound healing.
However, modern eye surgery is almost all minimally invasive, self-closing incisions. The incision size is mostly 0.4, 2, or 4 millimeters. In addition, when some operations are finished, the incision is already closed and no suture is required. wound. All of these determine that the incision of eye surgery will not be affected by blood sugar to a large extent, not to mention that eye surgery is almost always performed under the condition of good blood sugar control.
Strictly control blood sugar before surgery
The main ophthalmic surgeries involved in diabetic patients are: vitreous retina, cataract, and glaucoma. Before the operation, the doctor will let the patient try to control the blood sugar at a normal level. This is for the safety of the patient and also to reduce the possibility of postoperative infection.
Patients treated with oral hypoglycemic agents should stop metformin 24 hours before surgery, and all oral hypoglycemic drugs should be stopped on the night before and on the day of surgery. Sulfonylureas and Glinide oral hypoglycemic agents may cause hypoglycemia and should be stopped for at least 24 hours before surgery. For those who have poor blood glucose control with oral hypoglycemic agents, insulin therapy should be changed in time. Basal insulin combined with mealtime insulin can effectively improve blood glucose control.
Pay attention to care after surgery
After diabetic patients undergoing eye surgery, the eye disease is resolved, but the root cause of the eye disease has not been removed, so postoperative care should be strengthened. The specific measures are as follows:
1. Control blood sugar and weight. Diabetes patients should strictly control blood sugar, blood pressure and blood lipids, avoid overeating, and control blood sugar and weight through scientific diet and rational medication. Calculate the total calories ingested every day and do not exceed the limit. Protein accounts for about 15% of total calories, fat accounts for 25%, and carbohydrates account for 65%. Oily foods are mainly vegetable oils, such as peanut oil, soybean oil, and rapeseed oil. These oils can reduce the increase in blood lipids.
2. Pay attention to vitamin supplements. Foods containing vitamins and carotene are good for the eyes. The best source of vitamin A is the liver of various animals (the folks often use sheep liver as a good product for eyesight), cod liver oil, milk and eggs; foods rich in carotene include carrots, amaranth, spinach, leeks, green peppers, and sweet potatoes , And fruits such as oranges, apricots, and persimmons; vitamin C is one of the components that make up the eye lens. Foods rich in vitamin C include green peppers, cucumbers, cauliflower, cabbage, and fresh dates.
3. Stay away from tobacco and alcohol. Tobacco and alcohol are a major health killer for patients with diabetic eye disease and increase the risk of diabetic eye disease. Therefore, patients with diabetic eye disease need to stay away from tobacco and alcohol in daily life.
4. Avoid strenuous exercise. Diabetes patients should pay attention to avoid excessive or rapid exercise, so as not to induce bleeding in the fundus and cause unnecessary damage to the eyes.
5. Protect yourself when going out. When the sun is strong, you should wear protective goggles to avoid prolonged exposure to strong light to prevent sun-induced retinitis.
6. Adhere to healthy eyes. Avoid using electronic screens such as TVs and mobile phones for a long time. After intensive use of eyes every 40 to 50 minutes, look far and close your eyes to relieve eye fatigue.
7. Regular inspections. Diabetic patients need to undergo regular fundus examinations to monitor intraocular pressure. Early diagnosis and early treatment can help control the condition. Once measures such as diabetic retinopathy do occur, it will become difficult to reverse the condition.
