Can femtosecond surgery correct astigmatism

With the continuous development of modern medicine, femtosecond surgery, as a common refractive surgery, has attracted more and more attention from myopic patients. However, for astigmatism patients, the question they often care about is whether femtosecond surgery can correct astigmatism? This article will elaborate on this from four aspects: the operation principle, the operation effect, the operation risk and the applicable population.

Operation principle

Femtosecond surgery is a kind of surgical method that can change the shape of cornea by cutting it with laser technology, so as to correct vision. For astigmatism patients, the key to surgery is to create a specific shape cutting area on the cornea through the laser beam to change the curvature of the cornea, so as to correct astigmatism. This surgical principle ensures the correction effect of astigmatism.

However, it should be noted that not all types of astigmatism can be completely corrected by femtosecond surgery. For some severe astigmatism or special types of astigmatism, other surgical methods may be needed or other treatment methods may be selected.

Surgical effect

Femtosecond surgery is effective in correcting astigmatism. According to the statistics of many clinical studies at home and abroad, the correction rate of astigmatism by femtosecond surgery is up to 90%, and the vision recovers quickly after surgery with stable effect.

It is worth mentioning that individual differences in surgery may affect the results of surgery. Therefore, when choosing the surgical method, patients need to fully consult the doctor, understand their own conditions, and choose the appropriate surgical method.

Surgical risk

Like other surgical methods, femtosecond surgery also has certain surgical risks. Preoperative evaluation and postoperative care are very important to reduce the risk of surgery.

In femtosecond surgery, common surgical risks mainly include corneal infection, dry eye, photosensitivity, etc. However, these risks can be effectively reduced and the safety and effect of the operation can be guaranteed through strict patient screening, standardized operation and postoperative care.

intended for

Femtosecond surgery is suitable for astigmatism patients within a certain range. In general, femtosecond surgery is suitable for patients with light astigmatism, and the eye health is good. For patients with severe astigmatism or other eye diseases, other surgical methods or other treatment methods may be required.

Therefore, when choosing the operation method, the patient should go to a formal eye hospital for professional examination and evaluation. The professional doctor should make a judgment according to the specific situation of the patient and choose the operation method that is suitable for him.

Summary

In conclusion, femtosecond surgery is an effective method for correcting astigmatism. The cornea is cut by laser and its shape is changed to correct vision. However, the effects and risks of surgery are related to individual differences in patients and eye conditions. Therefore, when choosing the surgical method, patients should fully consult professional doctors to understand their own situation, so as to make wise decisions.
