Risks of femtosecond surgery and related precautions
Femtosecond laser surgery in ophthalmic surgery is a modern method to treat myopia, astigmatism and presbyopia. Although femtosecond surgery has been widely used worldwide and its safety has been greatly improved, there are still some risks. This article will elaborate on femtosecond surgery from four aspects: surgical risk, postoperative complications, surgical indications and postoperative precautions.
1、 Surgical risk
The risks of femtosecond surgery mainly include intraoperative infection, surgical failure and postoperative visual instability. Although femtosecond surgery is non-invasive, there is still the possibility of infection during the operation. Therefore, when choosing an operating hospital, it is necessary to ensure that the hospital has a clean operating environment and that doctors and nurses have good operating habits.
In addition, femtosecond surgery may sometimes fail, resulting in unsatisfactory surgical results. The success rate of laser surgery is related to the patient's corneal condition, surgical equipment and doctor's experience. When selecting a surgical hospital, experienced professional doctors and advanced surgical equipment should be selected.
Postoperative visual instability is a common complication of femtosecond surgery. After surgery, the patient's vision may not reach the ideal level immediately, and it will take some time to recover. In addition, the vision may fluctuate in a period of time after surgery, which requires the patient to be patient and carry out correct eye care according to the doctor's instructions.
2、 Postoperative complications
Some complications may occur after femtosecond surgery, such as dry eye, keratitis and corneal edema. Postoperative xerophthalmia is a common complication. Patients may have dry eyes, pain, blurred vision and other symptoms. In order to prevent and alleviate dry eye, patients need to follow the doctor's advice, drop eye drops regularly and maintain eye hygiene.
Keratitis is another serious complication after surgery. After surgery, the patient's cornea may be infected, resulting in redness, swelling, pain and decreased vision. In order to reduce the risk of keratitis, postoperative patients need to pay attention to avoid eye injuries and infections, and use antibiotic eye drops for eye disinfection on time.
In addition, corneal edema is a common complication of femtosecond surgery. The patient's cornea may become swollen after surgery, resulting in decreased vision. In order to prevent and alleviate corneal edema, patients need to follow the doctor's advice, regularly use anti edema eyedrops, and avoid eye overexertion.
3、 Surgical indications
Femtosecond surgery is applicable to myopia, astigmatism and presbyopia patients over 18 years old. However, not everyone is suitable for surgery. Some patients with serious eye diseases, dry eyes or eye infections should not be operated on. In addition, pregnant and lactating women are not suitable for femtosecond surgery. Before deciding to undergo surgery, patients should receive a comprehensive eye examination and consult a professional doctor for advice.
4、 Precautions after operation
After femtosecond surgery, patients need to pay attention to some matters to promote recovery and avoid complications. First, avoid rubbing eyes and wiping eyes with force. This can cause infection and eye damage. Secondly, use eyedrops and protective glasses according to the doctor's instructions. This can reduce xerophthalmia and corneal irritation. In addition, avoid strenuous exercise and heavy work to prevent eye fatigue* It is important to visit again regularly, keep communication with doctors, and seek medical advice in time to deal with any abnormalities.
summary
Femtosecond surgery is an effective ophthalmic treatment, but there are still risks and complications. Choosing an experienced professional doctor and a hospital with advanced equipment, following the doctor's suggestions and postoperative precautions, can * reduce the risk to a large extent and ensure the surgical effect. Not only that, patients should have a comprehensive examination before undergoing surgery to ensure the surgical indications, and keep close contact with doctors to jointly promote the success of the operation.
