Advantages of femtosecond surgery

Femtosecond surgery is a modern ophthalmic surgery technology, gradually replacing the traditional laser surgery. Compared with traditional laser surgery, femtosecond surgery has some obvious advantages. This article will elaborate on the advantages of femtosecond surgery from the following aspects.

High accuracy

Compared with traditional laser surgery, femtosecond surgery uses a high-speed rotating laser in the process of corneal ablation, which can cut tissue with nanosecond precision. This high accuracy ensures the accuracy and predictability of the operation and greatly reduces the risk of the operation.

Traditional laser surgery may produce some errors in the process of corneal ablation, resulting in unsatisfactory results. The femtosecond surgery can perform accurate corneal ablation according to the parameters set by the doctor in advance, avoiding the problems caused by errors in traditional surgery.

For example, a hospital has introduced femtosecond surgical equipment from China, and experienced doctors use femtosecond technology to perform cataract surgery, with a success rate of more than 98%.

Fast recovery

Femtosecond surgery is more accurate than traditional laser surgery, which can largely preserve the integrity of corneal tissue and reduce the damage to the cornea caused by surgery. This also means faster recovery after surgery.

In traditional laser surgery, because the cutting surface of the cornea is not smooth enough, it takes a long time to recover. In femtosecond surgery, because the cut surface is more flat, the epithelial cells on the cornea can recover and reconstruct faster. Therefore, the postoperative vision of patients undergoing femtosecond surgery can often be quickly restored in a short time.

Some patients can return to normal daily life within a few days after receiving femtosecond laser surgery, which greatly improves the quality of life of patients.

High security

Femtosecond surgery is highly safe. First of all, femtosecond laser only makes minor adjustments to the cornea, and will not damage other tissues of the eye. Secondly, femtosecond surgery can be customized according to the specific conditions of patients, avoiding the general treatment in traditional surgery. In addition, the laser energy used in femtosecond surgery is relatively low, reducing the risk of infection and other complications.

In nearly one thousand femtosecond operations carried out in a well-known ophthalmic hospital in China, the incidence of postoperative complications was only 0.5%, far lower than that of traditional laser surgery.

Easy to operate

Femtosecond surgery is simpler than traditional laser surgery. Traditional laser surgery requires doctors to control the laser beam in real time and cut the cornea.

Femtosecond surgery uses the high-speed rotation of the laser and the precise control of the computer to complete corneal ablation in a very short time. This makes the operation more stable and reliable, and greatly reduces the operation time.

These are the obvious advantages of femtosecond surgery. High accuracy, rapid recovery, high safety and simple operation are the important reasons why femtosecond surgery is widely recognized in the field of ophthalmology. With the continuous development of technology, it is believed that femtosecond surgery will be popularized and applied in more hospitals.

summary

As one of the important techniques of modern ophthalmic surgery, femtosecond surgery has advantages in many aspects. It has the characteristics of high accuracy, rapid recovery, high security and simple operation. Femtosecond surgery not only improves the success rate of surgery, but also significantly improves the postoperative experience of patients. With the continuous development of technology, femtosecond surgery is expected to be popularized and applied in more hospitals.
