What are the advantages of femtosecond surgery?
Ophthalmic femtosecond technology is a major breakthrough in the medical field in recent years, and has achieved remarkable results in the treatment of myopia, astigmatism and other eye diseases. As an accurate and reliable treatment, femtosecond surgery has been widely used in the ophthalmology department of Wuhan Union Medical College Hospital. The following will introduce its advantages in detail from four aspects: preoperative examination, surgical process, postoperative recovery and long-term effect of femtosecond surgery.
Preoperative examination
First, femtosecond surgery has obvious advantages in preoperative examination. Through advanced instrument detection, doctors can accurately analyze and measure the patient's corneal morphology, providing a strong basis for surgery. This makes the operation more accurate and reliable, and avoids possible errors in traditional preoperative examination.
Secondly, the preoperative examination process of femtosecond surgery is simple and rapid. The patient only needs to carry out a comprehensive examination, including the measurement of corneal thickness, pupil diameter, eye axis length and other parameters, and then a detailed surgical plan can be obtained. Compared with traditional surgery, it saves patients' time and energy and improves the efficiency of surgery.
Finally, femtosecond surgery can also conduct personalized preoperative evaluation according to the individual conditions of patients. Through the comprehensive analysis of corneal morphology and diopter, doctors can better understand the patients' eye conditions and provide guarantee for the smooth operation.
Operation process
The operation process of femtosecond surgery is relatively simple and fast, which reduces the operation risk. During the operation, doctors use advanced laser equipment to micro cut the cornea through a high-precision workbench to achieve the operation goal. Compared with traditional surgery, femtosecond surgery has the following obvious advantages.
First of all, femtosecond surgery does not require a scalpel, which avoids the adverse consequences of inaccurate scalpel cutting in traditional surgery. At the same time, femtosecond laser is highly controllable when cutting corneas, which can accurately control the depth and shape of the surgery, giving patients a better surgical experience.
Secondly, the cutting speed of femtosecond surgery is extremely fast, hundreds of thousands of laser pulses can be completed per second, greatly improving the efficiency and safety of surgery. This greatly shortens the operation time, reduces the discomfort of patients during the operation, and reduces the anxiety of patients.
Finally, femtosecond surgery is characterized by low reactivity and low risk of complications. Femtosecond laser is only used to micro cut the corneal surface, which will not affect other eye tissues, reducing the risk of surgical trauma and complications. At the same time, the high controllability of femtosecond laser makes the operation process more accurate and greatly reduces the rate of adverse reactions.
Postoperative recovery
Femtosecond surgery has obvious advantages in postoperative recovery. First of all, the surgical wound is small and the postoperative recovery is fast. The femtosecond laser cut cornea is less traumatic and does not need to be sutured. There will be no obvious pain and eye discomfort after surgery, and patients can live a normal life faster.
Secondly, the postoperative vision recovered quickly. Femtosecond surgery only micro cuts the cornea during the operation, which reduces the interference of ocular structures such as vitreous body, and makes the postoperative vision of patients recover more quickly. Most patients can feel the obvious improvement of vision on the second day after the operation.
Finally, the impact of femtosecond surgery on eye health in the later stage is small. Femtosecond laser micro cutting has less damage and less damage to the corneal structure. The corneal structure is more stable after surgery, reducing the risk of complications such as corneal dryness and keratitis after surgery.
Long term results of femtosecond surgery
Femtosecond surgery also shows obvious advantages in long-term effect. Years of clinical practice has proved that the therapeutic effect of femtosecond surgery is stable and reliable, and is not easy to recur. The study found that more than 90% of patients can achieve ideal vision within one year after surgery, and the effect of surgery can last for several years, or even benefit for life.
In addition, femtosecond surgery can also take into account the personal needs of patients. According to the patient's age, occupation, living habits and other factors, doctors can make personalized surgical plans according to different situations, so that the surgical effect is more in line with the patient's personal expectations.
In conclusion, femtosecond surgery has obvious advantages in the accuracy of preoperative examination, controllability of surgical process, rapidity of postoperative recovery and stability of long-term effect. As a modern ophthalmic treatment, femtosecond surgery provides patients with a more safe and efficient treatment of eye diseases.
