Application of femtosecond laser in Wuhan Army General Hospital and its risks and complications
Highly developed technology has provided many effective treatments for ophthalmology, including femtosecond laser. Wuhan Army General Hospital is a formal medical institution, which also uses femtosecond laser technology to treat eye problems. However, like other medical means, femtosecond laser also has some risks and complications. This article will elaborate on these issues from four aspects: preoperative evaluation, surgical risks, complications and potential consequences.
Preoperative evaluation
Femtosecond laser therapy requires a detailed preoperative evaluation to ensure that the physical condition is suitable for the surgery and reduce the risk. The doctor will make a comprehensive assessment of the patient's eye health, including checking the corneal curvature, fundus conditions, any eye diseases, etc. At the same time, doctors will also know the patient's physical condition and medication to determine whether there are risk factors related to surgery.
Patients not suitable for femtosecond laser include:
1. Pregnant women or lactating women: laser may have adverse effects on fetuses and infants.
2. People with eye infection or inflammation: laser surgery may aggravate eye infection or inflammation.
3. Severe dry eye patients: The operation may aggravate dry eye symptoms.
4. People with corneal weakness or corneal deformation: The operation may cause irreversible damage to the cornea.
Surgical risk
Femtosecond laser surgery itself has certain risks. Although doctors will try their best to control these risks, they cannot completely eliminate them.
1. Stress reaction: The operation process may lead to stress reactions in the patient's body, such as tension, anxiety, etc. This may have a certain impact on the surgical results.
2. Inaccurate control of cutting depth: Femtosecond laser surgery requires precise control of cutting depth to avoid unnecessary damage to eye tissue. However, due to the different eye structure and diopter of each patient, it may be difficult to accurately control the cutting depth.
3. The cutting area is too small or too large: the size of the cutting area is of great significance to the treatment effect. If the cutting area is too small, the diopter may not be completely corrected, while if the cutting area is too large, the cornea may be weakened.
complication
Femtosecond laser surgery may have some complications, although these are relatively rare.
1. Postoperative infection: eye tissue infection may be caused during the operation, especially if the operation hygiene requirements are not strictly followed.
2. Postoperative xerophthalmia: The operation may cause discomfort such as dryness and burning of the eyes, which may be caused by the reduction of tear secretion after the operation.
3. Keratitis: Keratitis after surgery may affect postoperative vision recovery, and even lead to blindness in serious cases.
Potential consequences
If complications or other problems occur during femtosecond laser surgery, the following potential consequences may result:
1. Incomplete vision recovery: The vision recovery after surgery may not be as expected, and additional treatment or surgery is required.
2. Deterioration of vision: The operation may lead to decreased or worsened vision, which may be due to the damage to the eye tissue during the operation.
3. Infection and pain: eye infection and pain may occur after surgery, which may require further treatment.
In conclusion, although femtosecond laser surgery is widely used in ophthalmology, it is not applicable to all patients. The importance of preoperative evaluation cannot be ignored, and the risks and complications of surgery also need to be correctly understood and faced by patients. Only after full consideration and evaluation by professional doctors can patients make a wise decision to choose whether to accept femtosecond laser surgery.
Summary
Femtosecond laser, as an ophthalmic treatment technology in Wuhan Army General Hospital, has many advantages, but also has certain risks and complications. The comprehensiveness and accuracy of preoperative evaluation are critical to the safety and success of surgery. The surgical risks mainly include stress reaction, inaccurate control of cutting depth, and too small or too large cutting area. Possible complications include postoperative infection, postoperative xerophthalmia and keratitis. The potential consequences may include incomplete recovery of vision, deterioration of vision, infection and pain. Therefore, before choosing to accept femtosecond laser surgery, patients need to fully understand these risks and complications, and make decisions under the guidance of professional doctors.
