Zhengzhou Aier Hospital femtosecond
In recent years, with the continuous development of ophthalmic technology, Zhengzhou Aier Hospital has introduced femtosecond surgery to treat myopia. This advanced surgical technology has brought new treatment options to patients and greatly improved their quality of life. Next, we will introduce how to treat myopia with femtosecond surgery in Zhengzhou Aier Hospital from four aspects.
Operation principle
Femtosecond laser technology was used in the femtosecond surgery of Zhengzhou Aier Hospital, that is, ultra fast laser pulses were used in the laser surgical blade to make corneal tissue evaporate and vaporize at the micron level. During surgery, doctors will use femtosecond laser to create a specific interface inside the cornea, and then use the laser to cut the corneal surface of myopic patients to form a thin corneal flap. Next, the doctor irradiates the laser on a certain point in the center of the eye through the corneal surface cut by surgery, thus changing the curvature of the cornea and correcting myopia.
The feature of femtosecond surgery is that it does not need to scrape the cornea, and it almost does not damage the biomechanical properties of the cornea. At the same time, this kind of surgery has high accuracy and safety, which can effectively avoid the complications of traditional laser surgery, such as dry eyes and serious infection.
Preoperative examination
Before femtosecond surgery, doctors will conduct a series of preoperative examinations on patients. These examinations include axial length measurement, corneal topography and diopter measurement, and these results are used to determine the surgical parameters and whether it is suitable for femtosecond surgery. The purpose of preoperative examination is to ensure the safety and effectiveness of the operation.
In Zhengzhou Aier Hospital, patients can conveniently book preoperative examinations through the online appointment system, saving time and energy.
Operation process
Femtosecond surgery is generally divided into three stages: preoperative preparation, surgical operation and postoperative nursing.
In the preoperative preparation stage, the doctor will communicate with the patient to understand the patient's medical history and eye condition in detail. Preoperative preparation includes preoperative examination and patient's physical condition assessment.
The operation stage is mainly for operation. During the operation, the doctor will drop some anesthetic on the surface of the patient's eyes so that the patient will not feel pain. Then, doctors use femtosecond laser to cut a corneal flap in the cornea, and then turn the flap up to correct myopia with laser. The whole procedure is very fast and usually only takes a few minutes.
Postoperative nursing stage is mainly about examination and nursing after operation. The doctor will review the patients after surgery to help them better adapt to corneal changes and provide eye care guidance.
summary
Femtosecond surgery in Zhengzhou Aier Hospital has a significant effect in the treatment of myopia. It is a safe, effective and non-invasive surgical method. Through surgical adjustment, patients' vision can be significantly improved. Through accurate and meticulous preoperative examination, accurate surgical operation and perfect postoperative nursing, patients can easily get rid of myopia and regain clear vision.
