The difference between femtosecond surgery and traditional laser surgery in Guangzhou People's Hospital

1. Technical principle

Traditional laser surgery uses laser irradiation, which is corrected by evaporating corneal tissue. The femtosecond surgery in Guangzhou People's Hospital uses femtosecond laser technology, which is a more advanced laser surgery technology. Femtosecond laser uses ultra fast pulse laser for correction, which can complete corneal cutting in a very short time, accurately control the depth of the laser, and avoid thermal damage to surrounding tissues.

2. Operation effect

Traditional laser surgery has achieved some results in correcting myopia, hyperopia and astigmatism, but its accuracy and stability are relatively poor. The femtosecond surgery in Guangzhou People's Hospital can adjust the corneal curvature more accurately, and improve the accuracy and stability of the surgery. Femtosecond surgery can also carry out personalized correction, and surgical design can be carried out according to each person's specific situation to obtain better correction effect.

In addition, because the femtosecond surgery has less damage to the corneal tissue, the postoperative recovery is faster, and the postoperative vision recovery effect is also better. However, traditional laser surgery may cause postoperative complications such as pain and corneal edema.

3. Correction scope

Traditional laser surgery has some limitations in the degree of correction, which can only correct myopia, hyperopia and astigmatism. Femtosecond surgery can be more widely applied to different degrees and types of ametropia. Femtosecond surgery can correct a wider range of degrees, and can also adjust the corneal level, which is applicable to the correction of more different vision problems.

4. Safety

The traditional laser surgery has some risks due to the need to cut cornea during the operation. Femtosecond surgery can complete cutting in a very short time, reducing the risk and discomfort of surgery. Femtosecond surgery adopts more accurate control technology, which can reduce the damage to the eyes during the surgery and improve the safety of the surgery.

Summary

Compared with traditional laser surgery, femtosecond surgery in Guangzhou People's Hospital is very different in technical principle, surgical effect, correction range and safety.

Femtosecond laser technology is used in femtosecond surgery, which makes the operation more accurate, the surgical effect better, and the postoperative recovery faster. Femtosecond surgery can be more widely applied to different degrees and different types of ametropia, and has high safety.

Therefore, the femtosecond surgery of Guangzhou People's Hospital is a more advanced, safer and widely used ophthalmic surgery technology, which can provide patients with better vision correction effect and surgical experience.
