Is there any risk of femtosecond surgery in the department of ophthalmology of Zhongshan Second Hospital in Guangzhou?
The Ophthalmology Department of Guangzhou Zhongshan Second Hospital is a well-known ophthalmic hospital, which provides a variety of ophthalmic operations, including femtosecond laser surgery. Many patients are concerned about whether the operation is risky when considering the operation. The risks of femtosecond surgery in the Department of Ophthalmology of Guangzhou Zhongshan Second Hospital will be described in detail in the following four aspects: the principle of surgery, precautions before and after surgery, postoperative recovery and surgical effect.
Operation principle
Femtosecond laser surgery is an ophthalmic surgery to correct myopia, hyperopia and astigmatism through laser technology. During the operation, the patient's corneal surface is stratified by laser, and then the corneal tissue is peeled off. Finally, the laser is used to reshape the corneal shape. The whole operation process is controlled by computer, with high precision and adjustability. However, like any surgery, laser surgery also has certain risks.
First, surgery may lead to unstable vision after surgery. Although most patients can get obvious vision improvement after surgery, some patients may have vision fluctuations or blurring, which usually requires follow-up and further treatment.
Secondly, surgery may also cause dry eye. After surgery, the nerves on the corneal surface will be damaged, which will lead to the patient's dry eyes, tingling and other uncomfortable symptoms. Usually, these symptoms will relieve themselves within a few weeks, but some patients may need to use artificial tears and other auxiliary treatment methods for a long time.
Finally, there may be a risk of infection after surgery. Although the ophthalmology department of Zhongshan Second Hospital in Guangzhou strictly implements aseptic operation, bacteria may still be introduced into the operation, leading to postoperative infection. Therefore, postoperative personal hygiene and postoperative care are very important.
Precautions before and after operation
Before undergoing the femtosecond ophthalmic surgery of Guangzhou Zhongshan Second Hospital, the patient needs to undergo a comprehensive ophthalmic examination to evaluate the indications of the surgery and the patient's eye condition. Patients must understand the risks of surgery and postoperative precautions, and sign the informed consent form before surgery.
After surgery, patients need to follow the doctor's instructions, use anti-inflammatory drugs, eyedrops and other drugs on time, and return regularly to ensure good results after surgery. In addition, patients should also pay attention to eye hygiene and avoid rubbing eyes and contacting pollutants to prevent infection and other complications.
Postoperative recovery
Postoperative recovery requires patient patience and cooperation. Usually, patients will feel slightly blurred vision and discomfort within a few days after surgery, which is normal. Patients should also pay attention to rest, avoid strenuous exercise and eye friction, so as not to affect corneal healing.
After one week, the vision of most patients will improve significantly. However, the recovery process after surgery varies from person to person, and some patients may take longer to fully recover. Therefore, it is necessary to keep close contact with the doctor after the operation and report any abnormal symptoms in a timely manner.
Surgical effect
The femtosecond surgery in the department of ophthalmology of Zhongshan Second Hospital in Guangzhou has a good effect. According to statistical data, most patients can significantly improve myopia or hyperopia and restore clear vision after surgery. The effect of surgery can usually last for many years, even for life.
In general, the risk of femtosecond surgery in the ophthalmology department of Zhongshan Second Hospital in Guangzhou is low, but there are still some risks. When considering surgery, patients should carefully evaluate their personal conditions and make decisions under the guidance of doctors. Only by fully understanding the risks and precautions of surgery can we better grasp the benefits brought by surgery and obtain ideal visual correction effect.
