Applicable population of femtosecond surgery

Femtosecond laser surgery is a highly accurate and safe refractive surgery, which is widely used in the treatment of myopia, hyperopia, astigmatism and other eye diseases. Although femtosecond surgery has significant advantages over traditional laser surgery in many aspects, it is not applicable to everyone. The following will introduce the applicable population of femtosecond surgery from different perspectives.

1. Myopic patients

Femtosecond surgery is an effective refractive correction solution for myopia patients. Myopia is a common ophthalmic disease, which makes patients have blurred vision at a distance. Femtosecond surgery corrects myopia by using lasers to change the shape of the cornea. Myopic patients can obtain obvious vision improvement through femtosecond surgery, and get rid of relying on glasses or contact lenses.

However, before choosing femtosecond surgery, myopic patients should meet certain conditions. First of all, the degree of myopia of patients should be stable and no longer grow. Secondly, the patient's corneal thickness should meet the requirements of surgery to ensure the safety of the surgical process* Later, the patient should not have other serious eye diseases, such as keratitis, glaucoma, etc.

2. Hyperopia patients

In addition to myopic patients, femtosecond surgery is also applicable to a certain degree of hyperopia correction. The eyeball of hyperopia patients is too long or the cornea is too steep, which causes the light to focus in front of the retina, making distant objects blurred. By changing the shape of the cornea, femtosecond surgery can help hyperopia patients achieve clearer hyperopia vision, reduce or eliminate dependence on glasses and contact lenses.

Like myopic patients, hyperopia patients also need to meet some conditions before choosing femtosecond surgery. For example, the degree of hyperopia should be stable, the corneal thickness should meet the requirements, and there should be no other serious eye diseases. In addition, age is an important consideration. Generally, hyperopia patients aged between 18 and 45 years are the ideal candidates for surgery.

3. Astigmatism patients

Astigmatism is a kind of common ametropia, which is manifested by the abnormal curvature of some areas of the cornea, resulting in inaccurate, blurred or deformed focusing of light after focusing. Femtosecond surgery can correct astigmatism by adjusting the shape of the cornea, so as to effectively improve patients' vision problems.

Similar to myopia and hyperopia, astigmatism patients also need to meet some conditions before choosing femtosecond surgery, such as stable astigmatism degree, corneal thickness that meets the requirements of surgery, and no other serious eye diseases.

4. Patients with previous eye surgery complications

Femtosecond surgery is also a feasible treatment option for patients who have received other eye surgery and had complications. Traditional laser surgery may increase the risk of further complications for these patients, while femtosecond surgery reduces this risk by performing corneal ablation in a more accurate and safe manner.

Although femtosecond surgery has a significant effect on the above population, each patient's situation is unique and needs to make a final decision after consulting with ophthalmologists. Only on the premise of meeting the surgical conditions can the safety and effectiveness of the operation be ensured.

summary

Femtosecond surgery is a kind of refractive surgery for myopia, hyperopia and astigmatism. For patients eligible for surgery, femtosecond surgery can significantly improve vision problems and reduce dependence on glasses and contact lenses. However, the choice of femtosecond surgery requires careful assessment of the patient's condition and decision-making under the guidance of a professional ophthalmologist. Through scientific and reasonable selection, femtosecond surgery can provide safe and effective vision correction solutions for appropriate patients.
