What side effects does myopic surgery have?
Myopic surgery is a common surgical method to correct myopia, which can effectively improve patients' vision problems. However, like all other operations, myopic surgery also has some potential side effects. Before myopia surgery, it is very important to understand these side effects. Next, we will introduce the side effects of myopia surgery from four aspects: vision change, dry eye, infection and postoperative recovery.
1. Vision changes
After myopia surgery, patients may experience some vision changes. In the days or weeks after the operation, the patient may feel unclear vision, double shadow or deformation. This situation is mostly normal, because the eyes need a period of time to recover. Usually, these vision problems will gradually improve within weeks and months after surgery, but a few patients may have persistent vision problems. Therefore, when choosing surgery, patients need to fully understand the risks of surgery and have a detailed discussion with doctors.
In addition, although myopia surgery can reduce the degree of myopia, it cannot completely eliminate myopia. After surgery, glasses or contact lenses may still be needed to correct residual myopia.
2. Dry eye
Dry eye is one of the common side effects of myopia surgery. During the operation, cutting the corneal tissue will damage the nerves of the cornea, leading to the collapse of the visual field after the operation and corneal nerve dysfunction, which may lead to dryness, pain, redness, foreign body sensation and other symptoms. These symptoms usually gradually alleviate within weeks or months after surgery, but some patients may have persistent dry eye problems.
In order to alleviate dry eye symptoms, patients can use artificial tears, moisturizing eyedrops and other methods to help keep their eyes moist. If the dry eye problem is serious, the doctor may recommend other treatments, such as eye disease treatment or laser treatment to stimulate corneal regeneration.
3. Infection
During myopia surgery, the eyes will be exposed to the external environment, increasing the risk of infection. Postoperative symptoms of infection may include redness, swelling, pain, increased secretion, etc. If the patient has these symptoms after the operation, he should seek medical treatment immediately. Doctors usually prescribe antibiotic eyedrops to prevent or treat infection.
In order to reduce the risk of infection, patients need to have a detailed eye examination before surgery to ensure that there is no potential eye infection. At the same time, doctors need to follow strict aseptic operation during the operation to reduce the possibility of infection.
4. Postoperative recovery
The recovery period after myopic surgery is critical to the success of the surgery. The patient may feel uncomfortable in the eyes within a few days after the operation, and should pay attention to rest and protect the eyes. In a few weeks after the operation, the patient needs to return regularly to ensure the smooth progress of eye recovery.
During postoperative recovery, patients need to follow the doctor's advice, such as not rubbing eyes, avoiding strenuous exercise, and not touching water. Before fully recovering, the patient may need to temporarily avoid certain activities, such as swimming.
summary
Although myopic surgery can effectively improve patients' vision problems, there are also some side effects. Vision change, dry eye, infection and postoperative recovery are common side effects of myopia surgery. When considering myopia surgery, patients need to fully understand these side effects and have a detailed discussion with doctors. At the same time, it is also very important to choose a regular hospital and an experienced doctor for the operation to ensure the safety and success of the operation.
