How is laser femtosecond surgery different from traditional surgery in Guangzhou Hospital?
Laser femtosecond surgery is a modern ophthalmic surgery technology, which is widely used in some hospitals in Guangzhou for refractive surgery. Compared with traditional surgery, femtosecond laser surgery is significantly different in terms of postoperative recovery time, surgical effect, intraoperative risk and degree of pain. This paper will elaborate on the femtosecond laser surgery and traditional surgery from these four aspects.
Postoperative recovery time
Traditional surgery usually requires a longer recovery time after surgery, and patients need a longer rest and recuperation after surgery. The femtosecond laser surgery is characterized by rapid recovery. The patient can resume normal activities within a few hours after the surgery, which generally does not affect the patient's daily life. This is because the femtosecond laser surgery uses the laser to cut the cornea, and does not need the incision in the traditional surgery, which greatly reduces the time for corneal healing after surgery.
In addition, the pain of femtosecond laser surgery after surgery is also mild, and patients generally only need to use mild pain relievers to relieve discomfort. In contrast, traditional surgery requires a larger corneal ablation, and patients will feel pain after surgery.
Surgical effect
Femtosecond laser surgery has obvious advantages in surgical effect. During the operation, laser cutting has high precision, which can accurately remove the refractive error area on the corneal surface to correct vision. Traditional surgery often requires corneal ablation with a scalpel, which inevitably leads to errors or erosion of normal corneal tissue, thus affecting the surgical effect.
In addition, laser femtosecond surgery can better control the cutting depth and shape of the cornea, and the surgical process is more accurate. The depth and shape of corneal ablation in traditional surgery are often difficult to control, which may lead to unsatisfactory surgical results.
Intraoperative risk
Femtosecond laser surgery has lower intraoperative risk than traditional surgery. In femtosecond laser surgery, laser cutting does not directly contact the eyes, reducing the risk of infection that may occur during surgery. At the same time, because the operation process is more accurate, the probability of damage to surrounding tissues during the operation is lower.
Traditional surgery often requires contact with eyeballs and corneal ablation with scalpel, so the risk of infection is relatively high. At the same time, the traditional surgery has certain risks to the corneal ablation, which may cause additional damage to the cornea.
Degree of pain
Femtosecond laser surgery is less painful than traditional surgery. Femtosecond laser surgery is a non-contact surgery, which will not produce obvious pain during the operation. However, traditional surgery often feels obvious pain due to the need to contact the eyeball.
In addition, the operation time of laser femtosecond surgery is relatively short, which generally only takes a few minutes to more than ten minutes. Compared with traditional surgery, it shortens the operation time and reduces the patient's pain during the operation.
Summary
The femtosecond laser surgery in Guangzhou Hospital is significantly different from the traditional surgery in terms of postoperative recovery time, surgical effect, intraoperative risk and degree of pain. Femtosecond laser surgery has faster recovery time and lower pain, and the surgical effect and intraoperative risk are better controlled. Therefore, laser femtosecond surgery has become a relatively preferred ophthalmic surgery method, bringing better surgical experience and effect to patients.
