Is there any risk in Nanjing femtosecond surgery
In recent years, with the continuous development of medical technology, Nanjing femtosecond surgery as a common myopia correction surgery has gradually attracted people's attention. However, many people have doubts about the risks and side effects of this operation. This article will elaborate on the risks and side effects of Nanjing femtosecond surgery from four aspects: preoperative preparation, surgical process, postoperative recovery and potential risks, so as to help readers better understand this kind of surgery.
Preoperative preparation
Before the Nanjing femtosecond surgery, the doctor will carry out a detailed eye examination to ensure the health of the patient's eyes is suitable for surgery. These examinations usually include intraocular pressure measurement, corneal topography and tear film detection. If the patient has other eye problems, such as dry eye or retinopathy, the risk of surgery will increase. Therefore, before deciding to operate, the patient needs to fully communicate with the doctor and receive a comprehensive eye assessment.
In addition, patients also need to observe some preoperative taboos, such as stopping contact lenses for a certain period of time and avoiding the use of eye cosmetics. The purpose of these measures is to reduce the risk of surgery and improve the success rate of surgery.
Operation process
Nanjing femtosecond surgery is an operation to improve myopia by cutting and correcting the corneal surface with laser. The whole operation process usually takes only a few minutes, and the patient is awake under local anesthesia during the operation.
During the operation, doctors will use a device called femtosecond laser to astigmatize the patient's cornea and cut it into thin discs. Then, the doctor will lift the corneal flap and use the laser to correct myopia or astigmatism in the cornea. Finally, the doctor put the corneal flap back in place and the operation was completed.
Although Nanjing femtosecond surgery is widely considered as a safe and effective myopia correction surgery, there are still some potential risks during the operation. For example, complications such as infection, corneal flap detachment or displacement may occur during surgery. However, the incidence of these complications is usually low, and in most cases can be effectively controlled through timely treatment.
Postoperative recovery
After Nanjing femtosecond surgery, patients need to pay attention to postoperative care and doctor's guidance to ensure effective recovery of the eye. Within a few hours after surgery, patients may feel uncomfortable symptoms such as dry eyes, tears or slight pain. These symptoms usually relieve themselves within a few days.
In a few days or weeks after surgery, patients should use antibiotic eye drops and eye moisturizers as recommended by doctors to prevent infection and alleviate discomfort. In addition, patients need to avoid strenuous exercise, eye friction or contact with pollutants after surgery to avoid affecting corneal healing and surgical results. Patients also need to return to see doctors regularly for examination and assessment to ensure the effect of surgery and eye health.
potential risk
Although Nanjing femtosecond surgery is considered to be a relatively safe myopia correction surgery, there are still some potential risks. First, the effect of surgery may be uncertain, which may lead to poor vision, vision fluctuations or incomplete recovery of vision. Secondly, complications such as infection, dry eye, corneal scar or abnormal healing of corneal flap may occur during the operation. In addition, surgery may not be applicable to certain people, such as patients who are too old or have other eye diseases.
To sum up, Nanjing femtosecond surgery has some risks and side effects to some extent, but the risks are usually controllable, and most patients can obtain good vision correction results after surgery. For patients, it is very important to choose the appropriate hospital and doctor, and actively follow the preoperative and postoperative guidance. After fully understanding the risks and side effects of surgery, patients can make wise decisions and maintain appropriate expectations.
