How long is the validity period of femtosecond surgery in Wuhan PLA Central General Hospital?
Wuhan PLA Central General Hospital is a well-known hospital located in Wuhan, Hubei Province. Since 2011, the hospital has introduced femtosecond laser technology for myopia surgery. Femtosecond surgery is a laser based myopia correction method, and its validity is related to many factors. In this article, we will discuss the validity of femtosecond surgery in Wuhan PLA Central General Hospital.
Surgical techniques
First, let's understand the basic principle of femtosecond laser surgery. Femtosecond surgery uses lasers to cut the cornea to change its curvature, thus correcting myopia. Compared with traditional laser surgery, femtosecond surgery is more accurate and safe. The operation process is mainly divided into four steps: contacting the corneal layer, cutting the corneal layer, improving the flap layer and adjusting the corneal curvature. The advantage of this technology is that it can quickly correct vision, and patients can recover vision in a short time after surgery.
The validity of femtosecond surgery mainly depends on the stability of corneal remodeling. Generally speaking, the corneal curvature after surgery will stabilize within a few months. According to clinical experience, the vision of most patients after surgery is stable, and only a few patients may have vision changes. Therefore, the validity period of femtosecond surgery can be considered as long-term.
individual difference
However, there are individual differences in the validity period of femtosecond surgery. Different people may have different surgical results and recovery time. Some people may recover their vision within a few months after surgery, while others may take longer to achieve the best results. This depends on the individual's corneal biological characteristics, the accuracy and process of surgery, and the individual's treatment response.
In addition, individual differences may also lead to changes in vision after surgery. Some people may find that the degree of myopia increases again, which may require further corrective surgery. Therefore, before accepting femtosecond surgery, patients should fully understand the risks and possible consequences of surgery, and fully discuss with doctors.
matters needing attention
For patients undergoing femtosecond surgery, there are some precautions to remember. First of all, follow the doctor's advice for recovery care after the operation, including correct use of drugs and avoiding rubbing eyes. Secondly, regular follow-up visits should be made after the operation to ensure stable vision, and any possible vision recovery problems should be dealt with in a timely manner.
In addition, although femtosecond surgery can effectively correct myopia, it is not applicable to all people. Some individuals may not adapt to surgery, such as weak cornea, eye infection or disease. Therefore, before undergoing femtosecond surgery, a comprehensive eye examination and evaluation should be performed to determine whether the surgery is suitable.
summary
Femtosecond technology is an effective method of myopia correction in Wuhan PLA Central General Hospital. The period of validity of surgery is related to individual differences and corneal stability, which can usually last for a long time. However, patients should pay attention to individual differences and postoperative precautions, and have full discussion and follow-up with doctors.
Therefore, in general, the validity period of femtosecond surgery in Wuhan PLA Central General Hospital is long-term, but individual differences and correct nursing are also important factors that determine the effect of surgery.
