Femtosecond surgery can solve the problem of myopia
Femtosecond surgery is an advanced ophthalmic surgery technology. As a regular medical institution, Guangdong Grade III Grade A Hospital has introduced and applied this technology for many years. The appearance of femtosecond surgery has brought a glimmer of hope to myopic patients and solved their vision problems that have puzzled them for many years. The advantages of femtosecond surgery in solving the problem of myopia will be described in detail in the following four aspects: corneal curvature, refractive stability, surgical pain and recovery time.
Corneal curvature
Traditional myopia correction surgery, such as laser surgery, mostly uses cutting methods, which will lead to changes in the curvature of the corneal surface, resulting in maladjustment, dryness and other problems. Femtosecond surgery, on the other hand, directly acts on the inside of the cornea through the laser, and hardly affects the surface of the cornea. This keeps the corneal curvature relatively stable after the operation, reduces the discomfort after the operation, and greatly improves the success rate of the operation.
The course of femtosecond surgery is short. The number of femtoseconds and the interval time between femtoseconds vary for each patient. However, in all cases where we perform femtosecond surgery, the course of surgery is about 38 seconds. Therefore, during the whole operation, it can greatly reduce the damage to the cornea and reduce the recovery time after the operation.
After surgery, many patients reported that the corneal sensation was better than laser surgery, which could reduce the risk of corneal structural damage to some extent.
Diopter stability
The diopter of myopic patients usually increases gradually in adolescence, and tends to be stable after the eyeball matures. Traditional surgery is difficult to perform when the patient's diopter is unstable, and the surgery should be performed after the patient's diopter is stable. However, femtosecond surgery can be performed under the condition of unstable diopter, because its impact on the cornea is very small.
The production effect of femtosecond surgery is more stable, and the diopter changes less after surgery, which avoids the risk of deepening the myopia after surgery. This is an important breakthrough for those patients who need to correct their vision but whose diopter is still changing.
In addition, femtosecond surgery is also suitable for high myopia and diopter correction under special circumstances. This provides more options for patients with unsatisfactory results of traditional surgery.
Operation pain
Femtosecond surgery is more comfortable than traditional surgery. Traditional surgery is often accompanied by pain and discomfort, and patients need local anesthesia or even general anesthesia to perform surgery. The femtosecond operation only needs anesthetic eyedrops, and the whole operation process is almost painless, reducing the psychological burden of patients.
During the operation, patients only need to lie on the operating table, their eyes are fixed, and there are some users blinking times, but there will be pauses in the middle. After the operation, there will be no complications, but imagined injuries must occur, and they feel very comfortable.
Some patients even reported that they did not feel anything during the operation, but only saw the intraoperative imaging.
recovery time
The recovery time of femtosecond surgery is relatively short. After surgery, only a short recovery time is needed for the eyes, and the patients can soon achieve normal work and activities of daily life. The recovery time of traditional surgery is usually longer, and patients need more rest to gradually adapt to the new vision after surgery.
After femtosecond surgery, patients can also quickly resume physical exercise without too much exercise restrictions. This is of great significance for patients who need physical exercise and have higher requirements for quality of life.
In general, femtosecond surgery, as a relatively new method of myopia correction, is gradually becoming the first choice to solve the problem of myopia. It effectively solves the problems in corneal curvature, refractive stability, surgical pain and recovery time, and brings hope and change to the majority of myopia patients.
