Contraindications of femtosecond laser surgery in Wuhan Union Medical College Hospital

Femtosecond Laser Assisted Laser In Situ Keratomileusis (FLASIK) is a method of ophthalmic surgery using femtosecond laser, which can correct vision problems such as myopia, hyperopia and astigmatism. However, not all people are suitable for this operation. For some specific people, femtosecond laser surgery has contraindications. The following is a detailed introduction from several aspects.

1. Eye diseases

First, people with eye diseases are generally not suitable for femtosecond laser surgery. Eye diseases include but are not limited to keratitis, keratopathy and corneal irregularity. These diseases will lead to changes in the shape and structure of the cornea, which may affect the effect of surgery.

Secondly, for patients with severe dry eye, we should also carefully consider whether to perform femtosecond laser surgery. Because it is necessary to cut a flap like tissue in the cornea during the operation and perform laser correction under the tissue, this may further aggravate the dry eye symptoms and lead to discomfort.

In conclusion, if there is eye disease or severe dry eye, people should decide whether to perform femtosecond laser surgery under the guidance of professional doctors.

2. Age limit

Femtosecond laser surgery is usually suitable for adults over 18 years of age. Since children's eyeballs are still developing, surgery may have an irreversible impact on their vision and eye health. Therefore, people under 18 years old are not recommended to undergo this operation.

In addition, for older people, eye tissues and functions have become relatively old and may no longer be suitable for surgery. The doctor will evaluate according to the actual situation of the patient to determine whether it is suitable for femtosecond laser surgery.

3. Physical conditions

Some physical conditions may also become contraindications to femtosecond laser surgery. For example, people with autoimmune diseases, such as rheumatoid arthritis and lupus erythematosus, may have problems with the immune system that affect the surgical effect and healing process.

In addition, people with serious heart disease, hypertension and other systemic diseases should carefully choose whether to undergo surgery. Some drugs may affect the operation process or postoperative recovery, so the doctor should be informed of detailed health conditions before the operation.

4. Pregnancy and lactation

Femtosecond laser surgery is generally not recommended for pregnant and lactating women. This is because changes in female hormone levels during pregnancy and lactation may lead to changes in the morphology and structure of the cornea, thus affecting the surgical effect.

In addition, some drugs involved in the operation may have adverse effects on the fetus or baby. Therefore, in order to ensure the health of mothers and babies, it is recommended that pregnant and lactating women wait for an appropriate time before considering the operation.

Summary

The femtosecond laser surgery in Wuhan Union Medical College Hospital is an effective vision correction surgery, but not all people are suitable for it. Eye diseases, age restrictions, physical conditions, pregnancy and lactation may all become contraindications to surgery. Before deciding to perform femtosecond laser surgery, patients should conduct a comprehensive evaluation under the guidance of professional doctors to ensure the safety and effect of the surgery.
