How many degrees of myopia does the full femtosecond surgery in Guangzhou Grand Hospital apply to?
With the continuous progress of science and technology, ophthalmic surgery has gradually become more safe and efficient. As an advanced technology, full femtosecond laser surgery has attracted more and more attention in myopia correction. As a hospital with advanced equipment and rich experience, Guangzhou Grand Hospital provides full femtosecond surgery services, but what is the degree of myopia? This article will elaborate on it from four aspects: the principle of operation, the effect of operation, the risk of operation and the preparation before operation.
Operation principle
All femtosecond surgery is a kind of surgery to correct myopia by laser corneal ablation. Compared with the traditional laser surgery, the laser used in the full femtosecond surgery can cut the cornea more accurately, making the surgery process more safe and accurate. The operation does not require a scalpel, which reduces the risk of infection during the operation, and at the same time, it can better preserve corneal tissue and improve postoperative visual quality.
According to the experience of Guangzhou University Hospital, full femtosecond surgery is generally applicable to myopia patients whose degree is within 300 degrees. Good surgical results need to be carried out in a suitable patient group.
Surgical effect
The full femtosecond operation in Guangzhou Grand Hospital has a good effect. After surgery, the vision of patients will be significantly improved in a period of time after surgery. According to statistical data, more than 90% of patients can achieve significant vision improvement after surgery. Because more corneal tissue was retained during the operation, the vision quality after the operation was better and closer to the natural vision.
However, the effect of surgery may vary from individual to individual. Some patients may need to further adjust the surgery or wear auxiliary glasses to achieve better results. Before the operation, the patient should communicate and evaluate with the doctor in detail to understand the expected effect of the operation.
Surgical risk
As a common ophthalmic operation, full femtosecond surgery has good safety. However, there are still risks in surgery, including infection, dry eyes, corneal scars, etc. Doctors in Guangzhou Grand Hospital will evaluate the patient's condition and operation risk before operation, and take corresponding measures to reduce the risk.
According to the experience of the hospital, full femtosecond surgery is a safe and effective choice for myopia patients with a small number of degrees. For patients with high myopia, there may be a certain risk of surgery. Therefore, patients should conduct detailed assessment and consultation before deciding on surgery to understand the risks and possible consequences of surgery.
Preparation before operation
Before undergoing full femtosecond surgery, patients need to carry out a series of preoperative preparations. First of all, patients need to have a comprehensive ophthalmic examination, including fundus examination, vision test and intraocular pressure measurement. These examinations will help doctors assess the patient's eye condition and surgical indications.
In addition, patients also need to consult their doctors to understand the details and risks of surgery. The doctor will develop a personalized surgical plan according to the specific situation of the patient. Patients need to provide relevant medical history and drug use, so that doctors can more comprehensively assess the risk of surgery.
Summary
To sum up, the full femtosecond surgery in Guangzhou University Hospital is applicable to myopia patients whose degree is less than 300 degrees. The operation is based on advanced laser technology, and the operation effect is good, but detailed evaluation and communication are required before the operation. The operation risk is low, but individual differences and possible consequences still need to be considered. Before deciding on surgery, patients should have full consultation and discussion with doctors to understand the details and risks of surgery and make wise decisions.
