Who is not suitable for femtosecond surgery?

Femtosecond laser surgery is a modern ophthalmic surgery technology, which can be used to correct refractive errors, such as myopia, hyperopia and astigmatism. However, not everyone is suitable for this operation. With the help of ophthalmologists from Nanjing Dongda Hospital, we will discuss who is not suitable for femtosecond surgery.

1. Diseases and health problems

People with certain diseases and health problems may not be suitable for femtosecond surgery. First, people with corneal diseases (such as keratitis and corneal scar) may need to solve the problem through other treatment methods rather than surgery. In addition, people with severe eye infections or dry eyes are not suitable for femtosecond surgery. These diseases may increase the risk of surgery and lead to poor surgical results.

In addition, some chronic diseases such as diabetes, immune system diseases and congestive heart failure may also affect the results of surgery. These diseases may increase the risk of complications of surgery, so doctors usually evaluate the overall health of patients before surgery.

Finally, femtosecond surgery is not suitable for pregnant or lactating women. These physiological conditions may have a certain impact on women's eyes, so it is recommended to consider surgery after the end of pregnancy or lactation.

2. Vision problems and diopter

Although femtosecond surgery can correct many refractive problems in different degrees, for some special cases, the surgical effect may not be as expected. For example, if the diopter is excessive or unstable, the surgery may not achieve the desired results. In addition, special types of vision problems such as age-related visual loss (presbyopia) and glaucoma may also limit the scope of surgery.

3. Eye structure and conditions

Eye structure and conditions are also critical to the applicability of femtosecond surgery. For example, people with corneal weakness or degenerative diseases may not be suitable for femtosecond surgery, because surgery may further damage the cornea. In addition, abnormal eye shape, corneal structure or fundus problems may also affect the effectiveness and safety of surgery. The doctor will evaluate these conditions in a detailed eye examination and make decisions based on each patient's situation.

4. Psychological adaptability

Finally, having appropriate psychological adaptability to the operation is also one of the necessary conditions for accepting femtosecond surgery. The operation may bring some tension and discomfort, so the patient needs to have enough courage and psychological preparation. If patients have excessive fear or anxiety about surgery, they may not be suitable for femtosecond surgery.

summary

Femtosecond surgery is a high-precision ophthalmic technology, which can improve many people's vision problems. However, not everyone is suitable for this operation. Disease and health problems, vision problems and diopter, eye structure and conditions, and psychological adaptability are all important factors affecting the applicability of surgery. Under the guidance of experts from Nanjing Dongda Hospital, each patient will receive a detailed assessment before the operation to ensure the safety and effect of the operation.
