Guangzhou Ophthalmology Femtosecond Operation
Guangzhou ophthalmic femtosecond surgery is a common ophthalmic surgery technique, which is used to treat myopia, hyperopia, astigmatism, presbyopia and other ophthalmic diseases. This operation is safer and more accurate than the traditional operation method, with a shorter recovery time and a higher surgical success rate. Next, we will introduce the operation process of Guangzhou femtosecond ophthalmic surgery in detail from four aspects: preoperative preparation, surgical operation, postoperative nursing and surgical advantages.
Preoperative preparation
Before the Guangzhou ophthalmic femtosecond surgery, the patient needs to undergo a series of ophthalmic examinations to ensure the feasibility of the surgery. First, the doctor will conduct corneal topography and wavefront aberration examination to assess the patient's eye structure and vision. Then, doctors will use OCT scanner to check the thickness and shape of eye tissue to determine whether it is suitable for femtosecond laser surgery.
After confirming the feasibility of the operation, the doctor will communicate with the patient in detail to explain the process, risks and precautions of the operation. The patient needs to provide detailed personal medical history and medication, and comply with the doctor's preoperative taboo measures, such as stopping wearing contact lenses, avoiding cosmetics, etc.
In addition, a general examination is required before surgery to assess the patient's overall health and determine whether there are other potential risk factors. Only when it is confirmed that the patient is in good physical condition and the eye condition is appropriate, can he enter the operating room for Guangzhou Eye Surgery.
Operation
The femtosecond ophthalmic surgery in Guangzhou is mainly divided into the following steps:
1. Local anesthesia and positioning: local anesthesia will be given to the patient's eyes before the operation to reduce discomfort. Then, doctors will use femtosecond lasers to generate specific patterns of cell layer nicks on the patient's eyeballs for subsequent laser cutting.
2. Laser cutting: Next, doctors use femtosecond lasers to cut, peel and cut corneal tissue layer by layer to change corneal curvature and improve vision. The laser cutting process usually takes only a few minutes. During the operation, the patient needs to keep his eyes stable and follow the doctor's instructions.
3. Cleaning and staining: After the laser cutting is completed, the doctor will use normal saline for cleaning, and use a specific dye to check the cutting quality of the surgical area. This step is to ensure the accuracy and safety of the surgical effect.
4. Postoperative care: After the operation, the doctor will give the patient appropriate anti-inflammatory drugs and nursing guidance to promote wound healing and reduce discomfort. Patients usually need to avoid strenuous exercise, overuse and touching eyes, and follow the doctor's postoperative care recommendations.
Postoperative care
After femtosecond surgery in Guangzhou Ophthalmology Department, patients should pay attention to the following matters:
1. Avoid wiping eyes forcefully: The eyes after surgery are sensitive, and patients need to avoid wiping eyes forcefully to avoid stimulating the surgical area and infecting the wound.
2. Use of protective glasses: within a few days after surgery, patients should wear protective glasses designated by the doctor to prevent the eyes from external stimulation and injury.
3. Assessment of vision recovery: within a few weeks after the operation, the patient needs to return regularly. The doctor will assess the patient's vision recovery and make further adjustments as needed.
Surgical advantages
The femtosecond ophthalmic surgery in Guangzhou has the following advantages over traditional surgical methods:
1. High safety: Guangzhou ophthalmology femtosecond surgery uses laser technology for corneal cutting, completely avoiding the possible mechanical cutting risk of traditional surgery.
2. High precision: laser cutting technology can accurately cut the cornea to achieve better surgical results and reduce the risk of surgery failure and recurrence.
3. Short recovery time: Guangzhou ophthalmic femtosecond surgery has less trauma, and the recovery time is shorter than that of traditional surgery. The patients can quickly return to normal life and work.
