How to perform femtosecond surgery in Shanghai New Vision Eye Hospital
Shanghai New Vision Eye Hospital is a modern hospital focusing on ophthalmic medical technology. Among them, femtosecond surgery, as an advanced myopia correction surgery, has attracted much attention. This article will introduce in detail the specific process and technology of femtosecond surgery in Shanghai New Vision Eye Hospital.
Preparation before operation
Before femtosecond surgery, the hospital will conduct a comprehensive eye examination and evaluation to ensure that the patient's eye condition is suitable for surgery. The doctor will measure the curvature, thickness and astigmatism of the cornea, and understand the patient's medical history and personal needs in detail. In addition, the hospital will also explain the operation process in detail, and inform patients of precautions before operation.
On the last day before surgery, the patient needs to stop wearing contact lenses to ensure the stability of the cornea. On the day of operation, the patient needs to thoroughly clean the eyes, wear the anti bacteria clothing and surgical cap required for the operation, and receive local anesthesia.
Preoperative preparation is very important to ensure the smooth operation and postoperative recovery.
Operation process
Femtosecond surgery is a kind of laser surgery, which uses femtosecond lasers to change the shape of the cornea to correct myopia. The whole procedure usually takes only a few minutes.
First, the doctor will position the patient's eye to accurately locate the center of the cornea. Then, the laser will open the eyelid in a high-speed and high-precision manner according to the parameters set by the doctor in advance, and remove the epithelial cells on the surface of the eyelid in a manner similar to "withering".
Next, the laser will create a very thin corneal slice (also called flap) in the center of the cornea according to the degree of myopia of the patient and the degree of correction required. This step is often referred to as the "valving process". In this process, the laser generates tiny bubbles on the corneal surface through rapid vibration, and then sinks layer by layer until a complete flap is formed.
Finally, the doctor will lift the corneal flap, and the laser will irradiate the laser beam inside the cornea to change the curvature of the cornea to correct myopia. This process is often referred to as the "laser correction process". During the whole operation, the laser will conduct real-time detection and automatic adjustment of the patient's eyes according to the parameters preset by the doctor to ensure the safety and accuracy of the operation.
Postoperative care and precautions
After surgery, patients need to wear special goggles to protect their eyes, and receive detailed guidance and medication from doctors. Patients need to avoid wiping eyes, eye irritation, exposure to strong light and other situations, and at the same time, they should regularly return to check the recovery of the eyes.
The recovery process after surgery is usually fast, and the patient will gradually return to normal vision within a few days. However, it is still necessary to pay attention to diet and rest habits after surgery to avoid strenuous exercise and eye injuries.
In a word, the femtosecond surgery in Shanghai New Vision Eye Hospital is a kind of advanced myopia correction surgery, which can change the shape of the cornea through minimally invasive laser surgery on the cornea to correct myopia. The full preparation before operation and the precise control of the operation process ensure the accuracy and safety of the operation effect. Postoperative care and precautions are equally important and can promote rapid recovery of patients.
