How many degrees of myopia is full femtosecond surgery suitable for Guangdong Hospital of Traditional Chinese Medicine?
Myopia is a common refractive error of the eye, which has brought great trouble to people's life and work. As a professional ophthalmic hospital of traditional Chinese medicine, Guangdong Hospital of Traditional Chinese Medicine introduced full femtosecond surgery, which has become an effective way to solve the problem of myopia. So, how many degrees of myopia is suitable for full femtosecond surgery? I will elaborate from four aspects below.
1. Definition of myopia degree
The definition of myopia degree is mainly based on the length of eye axis and refractive power. The axial length of the eye refers to the length of the anterior and posterior diameters of the eyeball, which is an important indicator of myopia. The refractive power refers to the eye's ability to focus light. Too strong a myopic refractive power can lead to blurred images of distant objects. According to the definition of the World Health Organization, low myopia is -0.5D to -3.0D, medium myopia is -3.25D to -6.0D, and high myopia is above -6.25D.
Therefore, the degree of myopia suitable for full femtosecond surgery mainly focuses on low to moderate myopia. For patients with high myopia, full femtosecond surgery may not be effective, or it needs to be combined with other treatment methods.
2. Principle of full femtosecond surgery
Full femtosecond surgery is a kind of surgery that can correct myopia by laser micro cutting inside the cornea and changing its shape. It uses femtosecond laser to remove corneal tissue layer by layer to achieve transparent corneal morphological adjustment. Compared with the traditional laser principle, full femtosecond surgery is more accurate and safe.
3. Advantages of full femtosecond surgery
Compared with traditional laser surgery, full femtosecond surgery has obvious advantages in correcting myopia:
First of all, no mechanical cutting is required during the full femtosecond operation, which reduces the damage to the cornea caused by the operation and makes the postoperative recovery faster.
Secondly, full femtosecond surgery uses laser to remove corneal tissue layer by layer, which can more accurately control the degree of correction and improve the surgical effect.
In addition, full femtosecond surgery can also correct corneal irregularity and improve vision problems at the same time, which is better for patients with corneal problems.
4. Precautions for full femtosecond surgery
Before choosing full femtosecond surgery, patients need to pay attention to the following points:
First, a comprehensive ophthalmic examination is needed to determine whether full femtosecond surgery is suitable. For example, abnormal eyeball structure, corneal disease or other eye diseases may affect the surgical effect, which needs to be judged according to the specific situation.
Secondly, regular medical institutions should be selected for surgery. As a real hospital, Guangdong Hospital of Traditional Chinese Medicine has professional ophthalmologists and advanced equipment, which can provide safe and effective surgery for patients.
Finally, after the operation, it is necessary to strictly follow the doctor's instructions for nursing and further consultation to ensure the effect of the operation and the health of the eyes after the operation.
Summary
The full femtosecond surgery in Guangdong Hospital of Traditional Chinese Medicine is suitable for low to moderate myopia. Through accurate laser micro cutting technology, myopia can be effectively corrected. Compared with traditional surgery, full femtosecond surgery has the advantages of accuracy, safety, fast recovery, and better effect for patients with corneal problems. Before choosing the operation, it is necessary to carry out a comprehensive ophthalmic examination, and choose a regular medical institution for the operation. After the operation, close attention should be paid to nursing and further consultation. Through full femtosecond surgery, patients can get rid of myopia and regain clear vision.
