The difference between femtosecond surgery and LASIK in Guangzhou hospital

In myopia correction surgery, Guangzhou Hospital provides two common options: femtosecond surgery and LASIK. Although they can effectively correct myopia, there are some differences in surgical methods, recovery time and stability of effects. The differences between the two operations are described in detail below.

Surgical techniques

Femtosecond surgery uses femtosecond laser to cut the cornea, peel off the corneal layer after cutting, and then correct myopia through laser engraving. In contrast, LASIK (Orthokeratology) is to form a raised corneal flap inside the cornea, and then use a laser to carve the cornea. The different techniques of these two operations make the corneal tissue treatment different during the operation.

The advantage of femtosecond surgery is that it can cut the cornea more accurately, reducing the risk of complications caused by surgical errors. The LASIK operation is relatively more traditional and simple, with relatively low technical requirements for doctors.

recovery time

There are also some differences in recovery time between femtosecond surgery and LASIK surgery. Femtosecond surgery requires a longer recovery time. Because the process of corneal cutting and peeling is more complicated, patients may need a long time to restore the integrity of the corneal surface after surgery.

In contrast, the recovery time of LASIK is shorter. Since the operation was performed by making corneal flap, the integrity of the corneal surface was well protected after the operation, so the recovery time of the patient after the operation was relatively fast.

Effect stability

Femtosecond surgery and LASIK surgery are also different in terms of stability. Femtosecond surgery is to correct myopia by cutting and stripping the cornea. The surgical process is relatively more refined and can better maintain the stability of the cornea. This means that the correction effect of myopia after surgery is relatively more stable and lasting.

The LASIK operation is relatively simple. Although the effect of the operation can be stable, the corneal tissue will be damaged during the preparation of the corneal flap. The long-term stability requires the patient to experience the corneal repair process after the operation.

Summary

To sum up, there are some differences between femtosecond surgery and LASIK surgery in Guangzhou Hospital in terms of surgical technology, recovery time and stability of effect. Femtosecond surgery is usually more delicate and requires a longer recovery time, but the effect is stable; LASIK is relatively simple, with a short recovery time, but slightly less stable than femtosecond surgery. When choosing surgery, patients should make appropriate choices according to their own conditions and doctors' suggestions.
