Surgical risks and complications
Wuhan All Femtosecond Hospital is a formal and professional ophthalmic hospital, which provides laser all femtosecond vision correction surgery. The risks and possible complications of the surgery mainly include the following aspects:
1. Preoperative risk assessment
Before the full femtosecond operation, the hospital will conduct a detailed preoperative risk assessment to ensure the safety and adaptability of the operation. Preoperative assessment includes eye examination, fundus assessment, corneal topography and measurement, and comprehensive health assessment. According to the evaluation results, the doctor will determine the feasibility of the operation, and fully communicate and make decisions with the patient.
The purpose of preoperative risk assessment is to reduce the risk of surgery and ensure the safety and reliability of surgery. Although doctors will try their best to assess the preoperative risks of patients, there are still certain risks that may lead to failure of the operation or complications.
2. Operation risk
All femtosecond laser surgery is a minimally invasive surgery with relatively low risk. The operation uses laser technology to evaporate corneal tissue to correct myopia, hyperopia and astigmatism. During surgery, the laser system will accurately vaporize corneal tissue according to the pre calculated data. However, due to the different corneal conditions of each person, there are certain individual differences in the risk of surgery.
Operation risks may include intraoperative discomfort, intraoperative bleeding, infection, etc. Among them, intraoperative discomfort is one of the common surgical risks. The patient may feel tingling, burning or dryness during the operation. In addition, intraoperative bleeding and infection, although rare, still have a certain probability.
3. Complications
The complications of all femtosecond surgery are relatively few, but there is still a certain probability of occurrence. Possible complications include:
1. Infection: The risk of corneal infection after surgery may increase. The doctor will provide drugs to prevent infection before the operation, and strictly sterilize the surgical instruments.
2. Dry eye: After surgery, some patients may have dry eye symptoms, including dry eyes, foreign body sensation, tears, etc. This is because cutting corneal tissue during surgery will affect the nerve and tear secretion function of the cornea.
3. Vision problems: During the recovery of vision after surgery, a small number of patients may have vision problems, such as vision loss, vision fluctuation, etc. These problems may be caused by inaccurate corneal cutting process or problems in corneal healing process during surgery.
4. Precautions and preventive measures
Before the operation, the doctor will explain the risks and possible complications of the operation to the patient in detail, as well as the precautions and preventive measures after the operation. Some common considerations include:
1. Avoid overuse of eyes: within a few days after surgery, patients need to avoid overuse of eyes, including using computers, reading books, watching TV, etc. for a long time.
2. Eye protection: patients need to wear goggles for a period of time after surgery to avoid the impact of external stimuli on the eyes.
3. Regular revisit: patients need to be revisited regularly after surgery, and doctors will track and observe the recovery after surgery to find and solve possible problems in a timely manner.
summary
Wuhan All Femtosecond Hospital will conduct a detailed preoperative risk assessment when performing laser all femtosecond surgery to minimize the risk of surgery. However, surgical risks and complications still exist. Before surgery, patients need to fully understand the risks and precautions of surgery, and fully communicate with doctors before surgery to make wise decisions.
