What eye problems are applicable to half femtosecond in Yan'an Hospital?
Yan'an Hospital is a well-known hospital located in China, with advanced medical equipment and a senior medical team. Among them, half femtosecond laser surgery is an important ophthalmic technology in the hospital, which is widely used to treat various eye problems. This article will elaborate on half femtosecond in Yan'an Hospital from four aspects: cutting accuracy, surgical process, postoperative recovery and applicable diseases.
Cutting accuracy
Half femtosecond laser surgery is one of the most accurate ophthalmic surgery. This technology can produce tiny bubbles on the cornea and cut the tissue by laser to correct vision. Due to the high focus and high accuracy of the laser, half femtosecond surgery can accurately cut the cornea without causing too much damage to the surrounding tissues. This makes the operation process more safe and reliable, and effectively reduces the risk of operation.
In addition, the cutting ability of half femtosecond laser surgery can be adjusted according to different conditions of patients. Doctors can determine the depth and scope of cutting according to the patient's corneal curvature, myopia and other factors, so as to better meet the personalized needs of patients.
Operation process
Half femtosecond laser surgery is a non-invasive surgical method, and the whole surgical process does not require any incision on the surface of the eyeball. Before the operation, the doctor will give local anesthesia to the eyeball to ensure the patient's comfort.
During the operation, the patient only needs to lie on the operating table and fix his head on the surgical instrument. Doctors will use professional laser equipment to accurately irradiate the laser energy on the cornea for cutting and correction operations. The entire procedure usually takes only a few minutes, and the patient will not feel obvious pain or discomfort.
In addition, the half femtosecond procedure is also very safe. The laser equipment can maintain the comfort and safety of the patient's eyeball during the operation through the advanced cooling system. After the operation, the doctor will briefly check the patient and give some postoperative precautions.
Postoperative recovery
After half femtosecond laser surgery, patients can generally recover quickly. Usually, patients can feel the obvious improvement of vision on the day of operation. A few days after the operation, the patient needs to use eye drops according to the doctor's instructions, and avoid excessive eye fatigue and excessive intraocular pressure.
Although patients may have some slight discomfort during recovery, these discomfort often disappear quickly. In a period of time after the operation, the doctor will return to see the patient regularly and guide the patient to take some eye care measures to ensure the durability and stability of the operation effect.
Applicable diseases
Half femtosecond laser surgery is applicable to a variety of eye problems, including myopia, hyperopia and astigmatism. For myopic patients, half femtosecond laser surgery can correct vision by changing the curvature of the cornea. For hyperopia and astigmatism patients, half femtosecond laser surgery can improve vision by adjusting the shape of the cornea.
It should be noted that half femtosecond laser surgery is not applicable to all eye problems. Therefore, before undergoing surgery, the patient should conduct a detailed eye examination and evaluation to determine whether such surgery is suitable.
Summary
The half femtosecond laser surgery in Yan'an Hospital is a very accurate, safe and effective ophthalmic technology. Through high-precision corneal cutting and correction, half femtosecond surgery can help patients with myopia, hyperopia and astigmatism effectively improve their vision, and recover quickly and stably after surgery. However, before the operation, patients still need to conduct a comprehensive examination and evaluation according to the doctor's recommendations to ensure the safety and applicability of the operation.
