What are the risks of femtosecond surgery that need attention?
Nowadays, myopia has become a global vision problem. In order to get rid of the shackles of glasses and contact lenses, more and more people choose femtosecond laser surgery to correct myopia. As a developed area of China's medical industry, Guangdong has a number of top three hospitals providing femtosecond surgery services. However, although the femtosecond surgery technology is advanced, there are still certain risks that need to be carefully understood by patients before making decisions. This article will elaborate on the potential risks of femtosecond surgery in Guangdong's top three hospitals from four aspects: corneal decompensated excessive friction, inflammatory infection, corneal flap detachment and dry eye.
Decompensated excessive friction of cornea
Femtosecond surgery is an operation that corrects vision by cutting cornea with laser. During the operation, corneal decompensation and excessive friction may occur. This is because the corneal flap on the cornea is lifted and repositioned during surgery, which may lead to corneal nerve damage and corneal surface damage. The patient may have symptoms such as eye pain, burning sensation and dryness after surgery. In addition, if the recovery is not good, vision problems such as vision loss and reflection may also occur. Therefore, before surgery, doctors need to conduct a detailed examination of the patient's eyes to assess whether the patient is suitable for femtosecond surgery.
It is also important for patients to make preparations before surgery. The patient needs to inform the doctor of his/her medical history and medication used so that the doctor can assess the risk of surgery. In addition, the patient needs to use the eye care solution correctly according to the doctor's instructions after the operation to avoid eye friction and strenuous exercise, so as to protect the recovery of the cornea.
Inflammatory infection
Any kind of surgery has the risk of infection, and femtosecond surgery is no exception. After surgery, patients may have infection symptoms such as redness, swelling, pain, and increased secretion. Fortunately, the probability of infection is relatively low, but in case of infection, it is necessary to seek medical treatment in time to avoid deterioration of the condition. Guangdong Grade III Grade A Hospital has strict aseptic operation measures during the operation, but patients' own hygiene habits are also important factors to prevent infection. Patients should follow the doctor's advice, properly clean and use the eye care solution, and avoid touching pollutants.
Corneal flap detachment
In femtosecond surgery, the corneal flap is cut by a laser and then folded to one side for corrective surgery. During the process of corneal flap formation and folding, corneal flap detachment may occur. This may lead to surgery failure, vision loss and even the need for repair surgery. In order to avoid the risk of corneal flap detachment, doctors in Guangdong Grade III Grade A Hospital will be very careful during surgery and perform precise operations according to the characteristics of the patient's eyes. The patient should also pay close attention to the eye condition after the operation. If any abnormality is found, the patient should seek medical advice in time.
xerophthalmia
Dry eye after femtosecond surgery is a common complication. Due to corneal flap peeling and corneal damage, patients may have dry eye symptoms such as dry eyes, pain, foreign body sensation and blurred vision after surgery. For patients already suffering from dry eye, femtosecond surgery may aggravate the symptoms. Therefore, doctors will evaluate dry eye before surgery to avoid causing too much burden on patients' eyes. After surgery, patients need to use nursing eyedrops regularly, adhere to eye massage and eye exercises to promote corneal recovery.
Summary
To sum up, although the femtosecond surgery provided by Guangdong Third Class A Hospital can effectively correct myopia, there are still some risks. Uncompensated excessive friction of cornea, inflammatory infection, corneal flap detachment and dry eye are the main risks that patients should pay attention to when considering femtosecond surgery. In order to reduce these risks, patients should consult their doctors in detail to find out whether they are suitable for surgery, and care and recover according to their doctors' recommendations before and after surgery. The safety and effectiveness of femtosecond surgery can only be ensured if adequate preparation and risk assessment are made.
