What are the risks of femtosecond surgery in the ophthalmology department of Wuhan Army General Hospital?
Wuhan Army General Hospital is a hospital with rich experience in ophthalmic surgery and advanced equipment. As a modern refractive surgery, ophthalmic femtosecond surgery is widely used in the treatment of myopia, hyperopia and other eye diseases. However, any operation has certain risks. This article will elaborate on the risks of femtosecond surgery in Wuhan Army General Hospital from the aspects of preoperative evaluation, surgical complications, postoperative complications and surgical failure.
1、 Risk of preoperative assessment
1. The preoperative evaluation was not accurate. Although Wuhan Army General Hospital has a professional medical team, it is still difficult to make a completely accurate preoperative assessment. There may be errors in the measurement results of corneal curvature, diopter, axial length and other parameters measured before surgery, which may lead to poor vision after surgery.
2. Omission of preoperative detection. Due to individual differences and limitations of detection equipment, some eye diseases or refractive states may not be fully detected before surgery. These undetected potential problems may affect the effect of surgery.
3. Preoperative patient's personal factors. Some patients may have other serious diseases, such as diabetes, hypertension, etc., and may be taking some special drugs. These personal factors may increase the risk of ophthalmic femtosecond surgery.
2、 Risk of surgical complications
1. Injury to the inner structure of cornea. In ophthalmic femtosecond surgery, laser operates in the cornea, which has a certain risk of damaging the inner structure of the cornea, such as endothelial cells or the anterior membrane, resulting in a rough surface of the cornea, thus affecting the visual effect.
2. Risk of infection. Any surgery has the risk of infection, and ophthalmic femtosecond surgery is no exception. During the operation, if the disinfection is not complete or the operation is not standardized, it may lead to postoperative infection and further affect the recovery of vision.
3. The vision recovers slowly. Although the therapeutic effect of ophthalmic femtosecond surgery is relatively accurate, the recovery process of vision after surgery is very different among individuals. Some patients may need a longer time to achieve the desired vision effect.
3、 Risk of postoperative complications
1. Dry eye. Ophthalmic femtosecond surgery may damage the corneal nerve, leading to the occurrence of dry eye after surgery. Patients may have dry eyes, pain, inflammation and other symptoms.
2. Photosensitivity. Patients after surgery may be sensitive to light, or even have problems such as light interference, which affects their daily life and work.
3. Visual fluctuation. Postoperative visual fluctuation is a common complication. Patients may have visual fluctuation, shadow, halo and other symptoms. These discomfort may persist for a period of time after surgery.
4、 Risk of surgical failure
1. The vision cannot reach the expected effect. Although the preoperative evaluation and surgical process are as accurate as possible, due to individual differences and other uncertain factors, some patients may not achieve the expected effect of postoperative vision.
2. Risk of recurrence. In a period of time after surgery, the diopter of some patients may change again, leading to blurred vision again, requiring another surgery or other treatment.
3. Postoperative complications cannot be completely repaired. Even if postoperative complications occur, some complications may not be completely repaired, affecting the visual effect and quality of life of patients.
In conclusion, the risks of femtosecond surgery in the ophthalmology department of Wuhan Army General Hospital include preoperative assessment risk, surgical complications risk, postoperative complications risk and surgical failure risk. Before choosing surgery, patients should fully understand these risks, fully communicate with doctors, and make decisions under the guidance of doctors.
