How does the femtosecond surgery in Qianfo Mountain Hospital improve vision?
As a well-known ophthalmic hospital, Qianfo Mountain Hospital has advanced medical equipment and an experienced team of doctors. Femtosecond surgery is a common method of vision correction in Qianfo Mountain Hospital. It can improve vision problems such as myopia, hyperopia and astigmatism through laser technology. This article will introduce how the femtosecond surgery in Qianfo Mountain Hospital can improve vision from four aspects.
1. Principle of femtosecond surgery
Femtosecond surgery is a vision correction method based on laser technology. Excimer laser is used to cut and reshape the thin layer of corneal tissue, so as to change the curvature of the cornea and achieve the purpose of vision correction. Femtosecond surgery is more accurate and safe than traditional laser surgery, and can effectively correct vision problems without destroying other eye tissues.
During surgery, doctors will use computer controlled laser equipment to peel off the surface layer of the cornea, then use laser beam to accurately remove and reshape the corneal tissue, and finally reposition the surface layer. In this way, by changing the curvature of the cornea, light can be correctly focused on the retina, thus improving vision problems.
2. Advantages of femtosecond surgery
Compared with traditional laser surgery, femtosecond surgery has the following advantages in correcting vision:
First, the operation of femtosecond surgery is more accurate and safe. Because of the laser technology, doctors can accurately control the operation process and avoid errors in the operation. At the same time, femtosecond surgery can also protect corneal cells and reduce the damage to the cornea caused by surgery.
Secondly, the operation process is faster and the recovery time is shorter. Traditional laser surgery requires relatively long operation time and recovery period, while femtosecond surgery can usually be completed in a few minutes, and the recovery period is also relatively short. The patient can return to normal life and work soon after the operation.
Finally, femtosecond surgery has a wide range of applications. In addition to the common myopia, hyperopia and astigmatism, femtosecond surgery can also be used to treat other corneal problems, such as corneal weakness and corneal scars.
3. Effect of femtosecond surgery
The femtosecond surgery in Qianfo Mountain Hospital has achieved remarkable results in improving vision. According to the statistical data of the ophthalmologists of Qianfo Mountain Hospital, most patients undergoing femtosecond surgery can feel the obvious improvement of their vision within a few hours after the surgery, and their vision is stable.
The vision problems that can be corrected by femtosecond surgery include myopia, hyperopia and astigmatism. The surgical effect is lasting, and patients can have clear vision without wearing glasses or contact lenses. According to patients' feedback, they can confidently carry out various daily activities, such as driving, working and doing sports after receiving femtosecond surgery.
4. Precautions and risks
Before undergoing femtosecond surgery, patients need to pay attention to some matters. First of all, it is necessary to select a regular hospital and experienced doctors to perform the operation to ensure the safety and success rate of the operation. Secondly, patients should understand the process and risks of the operation in detail before the operation, follow the doctor's advice, and get ready.
Although femtosecond surgery has achieved remarkable results in correcting vision, there are still some risks. Possible complications include infection, dry eye, corneal scar, etc. In addition, femtosecond surgery may not achieve ideal results for some special vision problems. Therefore, before deciding whether to accept femtosecond surgery, the patient should fully communicate with the doctor, weigh the advantages and disadvantages, and make a wise choice.
summary
The femtosecond surgery in Qianfo Mountain Hospital is a method to improve vision through laser technology. Its principle is to reshape the cornea through excimer laser, so as to change the curvature of the cornea and correct vision problems. Femtosecond surgery has the advantages of accuracy, safety, speed and wide application. The operation effect is obvious and the recovery time is short. However, patients need to pay attention to some matters before undergoing surgery and understand the risks of surgery. Although femtosecond surgery has achieved good results, there are still some risks and limitations.
