Advantages of femtosecond surgery
Ophthalmic surgery has been developing continuously. Femtosecond laser surgery, as an advanced method to treat myopia, has attracted the attention of the majority of patients. Femtosecond surgery has many advantages in myopia correction, which will be described in detail from four aspects: eye recovery time, surgical accuracy, complication risk and surgical effect.
Short eye recovery time
Compared with traditional laser surgery, femtosecond surgery has less erosion and trauma to the cornea. Femtosecond laser can form a controllable cutting layer inside the cornea, and the corneal recovery is faster after surgery. Traditional surgery takes weeks or even months to recover to the best state, while femtosecond surgery can recover to the ideal level within a few days after surgery.
In addition, femtosecond surgery has lower requirements on corneal thickness and shape, and smaller thinning amount of cornea, which reduces the risk of dry eyes and other complications after surgery, and makes eyes feel better after surgery.
Higher surgical accuracy
When the femtosecond laser passes through the high-energy pulse, it quickly releases energy to peel off a layer of cornea, greatly improving the accuracy of the operation. The surgical machine uses advanced fundus tracking equipment, which can monitor the changes of the eyeball and cornea in real time, and automatically adjust the surgical parameters to ensure the precision of the operation at the moment. The corneal tissue resident in traditional surgery is separated from the original beam due to the movement of the patient's eyeball, which affects the surgical effect. Femtosecond surgery avoids this problem.
In addition, femtosecond surgery can also carry out personalized treatment according to the individual differences of patients, which is more accurate and effective than traditional surgery.
Low risk of complications
Femtosecond surgery has a low risk of complications. First of all, the operation process is controlled by the laser, which reduces the direct contact of the operator to the cornea and reduces the operation risk. Secondly, the peeling layer of femtosecond surgery in the process of corneal ablation can provide patients with a better sense of surgical security, which greatly reduces the occurrence of accidents during surgery. In addition, the femtosecond surgery will be examined and evaluated in detail before surgery, and appropriate patients will be selected for surgery, which further reduces the risk of complications.
Lasting and stable surgical effect
The operation effect of femtosecond surgery is durable and stable. After surgery, it can not only effectively correct the degree of myopia, but also make the cornea more regular and tidy, and improve the visual quality of patients. Femtosecond surgery increases the elasticity of the cornea and improves the stability of myopia by changing the shape of the cornea. The postoperative myopic degree changes little, and the surgical effect is lasting.
Whether femtosecond surgery is worth choosing depends on personal circumstances. If the patient has myopia and wants to be corrected, femtosecond surgery is a very ideal choice. Its recovery time is short, its accuracy is high, the risk of complications is low, and the surgical effect is durable and stable. It can help patients get rid of the shackles of glasses and contact lenses. However, it should be noted that femtosecond surgery has a certain cost and needs to be carried out in a professional hospital. Patients should fully understand and consult before choosing.
Summary
As an advanced method of myopia correction, femtosecond surgery has obvious advantages. It can shorten the recovery time of eyes, improve the accuracy of surgery, reduce the risk of complications, and ensure a lasting and stable surgical effect. The choice of femtosecond surgery depends on individual conditions, but for patients in need, it is a very worthwhile treatment.
